Some pet emergencies outrun any checklist. If an animal is collapsing, struggling to breathe, or was exposed to something toxic, stop reading and call your veterinarian or the nearest emergency animal hospital now. When officials order an evacuation, go; nothing on this page is worth delaying your own exit. This article is spec-and-evidence analysis of published guidance, not veterinary care for your specific animal. Where your vet's instructions or an official order differ from anything here, they win.
Key takeaways
•Volcanic ash is not smoke. USGS calls it hard, abrasive, mildly corrosive, and says it does not dissolve in water. It is pulverized rock and glass that scratches eyes, cuts paws, and scars lungs, and it does not clear on its own.
•The order matters. Alaska's State Veterinarian and IVHHN both say brush dry ash off before your pet comes inside. Because ash is abrasive and does not dissolve, wetting it first turns it into a gritty paste, so brush or wipe dry, then damp-wipe.
•Eyes get rinsed, never rubbed. Alaska's State Veterinarian says keep saline eyewash on hand and only rinse, not rub, because the grit scratches the cornea. USGS lists corneal abrasion and foreign bodies in eyes as ash injuries.
•Ash contaminates food and water. IVHHN says keep animals' food and water clean, and the same logic applies to pet bowls. Alaska's State Veterinarian recommends covering or storing feed. Cover or bring in bowls, keep food sealed, pour from stored water.
•Watch the breathing. AVMA says coughing, gagging, difficulty breathing, eye watering, or nasal discharge mean you consult your veterinarian, and animals with heart or lung disease are especially at risk. Ash inhalation is a vet call, not a wait-and-see.
If you live in Alaska, Hawaii, the Pacific Northwest, or anywhere downwind of an active volcano, ashfall is a real and recurring hazard, and it is not the same problem as wildfire smoke. When Mount Spurr showed signs of a possible eruption in 2025, Alaska’s State Veterinarian issued guidance on protecting pets from ash, because it is a genuine and recurring worry for households downwind. The instinct to treat ash like a dirtier version of a smoky day is the dangerous part, because volcanic ash is a physically different thing, and it does the damage in a physically different way.
Here is the distinction that runs through this whole page. The USGS Volcano Hazards Program describes volcanic ash as “hard, abrasive, mildly corrosive, conducts electricity when wet, and does not dissolve in water”, and is explicit that it “is not the product of combustion, like the soft fluffy material created by burning wood, leaves, or paper.” It is pulverized rock and glass. That single fact, abrasive glass that will not dissolve, changes how you clean your pet, how you protect their eyes, and what you do with their food and water. Below is the ashfall playbook for pets, cited to volcano and ashfall authorities and to veterinary sources.
If your pet is coughing, struggling to breathe, or has a painful, squinting, or visibly scratched eye, that is a call-your-vet-now situation. Ash is abrasive, and an inhaled or in-eye exposure can injure rather than just irritate. Do not wait to see whether it clears on its own.
This is the core of it, so it is worth being precise. Wildfire smoke is mostly fine particulate and gases that disperse as the air clears. Volcanic ash is ground-up rock and glass that falls, settles, and stays, and it cuts and scratches what it touches. A blowing dust storm is a third thing again, arriving as a wall in minutes and carrying its own regional health question, which is why we handle it separately in our dust storm and haboob pet safety guide rather than folding it in here.
USGS spells out what that means for animals. Its guidance on ash impacts lists inhalation and respiratory discomfort, eye and skin irritation, abrasion of the teeth, and ingestion leading to gastrointestinal blockages among the effects on animals, along with fluorosis. On the human-health side, USGS lists foreign bodies in eyes and corneal abrasion as ocular impacts, and notes that prolonged exposure to the fine fraction can raise the risk of silicosis, because respirable crystalline silica is one of the components. Your pet’s eyes and airways are not built any tougher than yours.
So the parts of the smoke playbook that still apply are keep pets indoors and watch their breathing. What ash adds on top is a cutting and scratching problem: on the surface of the eye, on the paw pads, on the coat, and in the airways. Everything below is built around not grinding that abrasive grit into your animal while you try to help it.
Step 1: Keep Them In, and Seal the House
The single most protective thing you can do is keep pets indoors during the heaviest ashfall, and keep the ash outside with them out of it. IVHHN’s ashfall preparedness guidance is direct: “Keep pets indoors. If pets go out, brush them before letting them indoors.” Alaska’s State Veterinarian, Dr. Sarah Coburn, gives the same advice, recommending staying indoors as much as possible, particularly during that initial ashfall, and keeping pets on a leash or under a covered space when they do go out.
Sealing the house protects the pet you just brought inside. Both USGS and IVHHN say to close doors and windows, to place damp towels at door thresholds and other draft sources, and to tape draughty windows. That keeps the fine, respirable fraction from drifting in and settling on the floors your pet walks and licks. If you run a forced-air system that pulls in outside air, this is the time to shut it down rather than circulate ash through the house.
One more indoor rule that matters for pets specifically: do not dry-sweep the ash that gets tracked in. IVHHN warns that dry sweeping remobilizes ash back into the air, where it is easy to breathe. Dampen it first or vacuum it, and keep the pet out of the room while you do.
Step 2: Three Things to Have Before the Ash Falls
Ashfall is one of those hazards where a small amount of gear bought ahead of time does real work, and buying it during the event is too late. Three items earn their place, and each maps to a specific way ash hurts pets: the water it contaminates, and the paws and eyes it cuts.
Sealed water storage, because ash contaminates open water. IVHHN’s ashfall guidance is to keep animals’ food and water clean, and its household water advice is that if ash gets into the supply, you let it settle and use the clear water. That applies straight to your pet’s bowl. An outdoor bowl left out during ashfall is collecting the same abrasive grit you are working to keep out of your animal. Pouring from a sealed reservoir sidesteps that entirely.
Paw protection, because the ground is now covered in abrasive glass. Dr. Coburn lists foot booties among the gear worth using for ash. A boot with a real sole and a snug upper keeps the grit off the pads and cuts how much a dog tracks in and licks off. The fit and acclimation lessons in our dog boots for wildfire ash guide apply directly here, because a boot the dog has never worn is a boot it sheds in the yard.
Saline for flushing, because eyes and pads are where ash does its cutting. Dr. Coburn’s specific instruction is to keep saline eyewash on hand and to only rinse, not rub, since the ash is gritty and rubbing drags it across the surface of the eye. A pet-made saline spray covers both the eyes and a gritty paw.

WaterBrick 3.5-Gallon Stackable Water & Food Storage Containers (6-Pack)
A sealed reservoir lets you pour clean water for pets instead of using an open bowl that collects fallout; IVHHN's ashfall guidance is to keep animals' food and water clean, which applies directly to pet bowls
+A sealed, gasketed container keeps stored water clean while ash is falling, which is the whole point during an ashfall, since an open bowl left out collects the same abrasive grit you are trying to keep out of your pet
+The 6-pack holds 21 gallons, enough to carry pets and people through the days that ash keeps everyone indoors. It doubles as your general emergency water reserve the rest of the year
+Stacks and stores flat, so the reserve is realistic to keep on hand before you need it rather than something you scramble for once the mountain is venting
Cons
−This is water storage, not water treatment; if ash reaches your tap or your only supply, IVHHN's method is to let it settle and use the clear water, and a Do Not Drink notice still applies to pets
−Filled bricks are heavy at roughly 30 pounds each, so place them where they will live before filling them
−The linked listing is one configuration; confirm the current pack size and color on the product page, since pricing and variants are set there
During ashfall the job is simple: pour clean water from something sealed instead of letting your pet drink from a bowl that has been collecting fallout. A gasketed, stackable reservoir does that and earns its keep as your year-round emergency water at the same time. It stores water, it does not purify it, so pair it with the settle-and-use-the-clear-water rule if ash ever reaches your supply.
+A real sole and a snug air-mesh upper keep abrasive ash off the pads and out from between the toes, which is exactly the grit Alaska's State Veterinarian says to brush off and keep the dog from licking
+Sized by actual paw width rather than a vague small, medium, or large, so you fit the dog's foot and get a boot that is more likely to stay on during a stressful outing
+Breathable mesh vents the paw, which matters because a dog wearing boots for more than a quick bathroom trip still needs to shed heat through its feet
Cons
−A single cinch closure means a panicked dog can still work one loose. Fit and acclimation decide whether the boots stay on, so a dog meeting boots for the first time during an eruption will kick them off
−Ruffwear publishes no puncture or abrasion rating specific to ash, so treat these as a rugged barrier, not a certified one; the primary protection is still keeping the dog off the ash
−Sold in pairs and sized by paw width; the linked listing is one size and color, so measure all four paws and select your dog's size before buying, since pricing and variants are on the product page
Booties are on the state veterinarian's short list of gear worth using for ash, and a boot with a genuine sole and a snug mesh upper keeps the abrasive grit off the pads and cuts how much your dog tracks in and licks off. The limit is the same as with any boot: it only protects a dog that learned to wear it before eruption day. Size it, acclimate it now, and keep outings brief regardless.

Vet Aid Animal Wound Care Spray (Saline, 4 oz)
Vet Aid · Budget
Pet Saline Rinse for Ash on Paws and Coat
Spec
Value
Source
Type
Saline wound-care spray marketed for pets for cleansing minor wounds and irritations; it is a wound-care spray, not a sterile ophthalmic eyewash, so for eyes use it only as a gentle poured or dribbled flush
+Saline is exactly what the state veterinarian names for ash on a pet, and a pet-specific can is easy to aim one-handed at a gritty paw or coat while you steady a squirming animal
+Handles the spots ash cuts most, a scratched pad or a patch of irritated skin; for the eyes, decant or dribble it as a gentle flush rather than firing the spray at the surface
+Inexpensive, compact, and needs no acclimation, so it belongs in the kit for any household in an ashfall zone
Cons
−It rinses and flushes, it does not treat an injury; a scratched cornea or a cut pad still needs a veterinarian, and eye pain, squinting, or a visible scratch is a same-day vet visit
−A pressurized can aimed at the eye should be held back and used as a gentle flush, not a hard jet; if in doubt, clean saline or cool water poured over the eye also works
−The linked listing's fuller formulation claims sit on the product page; read the current listing before buying, since the description and pricing are set there
The state veterinarian's eye instruction for ash is specific: keep saline on hand and rinse, do not rub, because the grit scratches. A pet-made saline can puts that within reach for a gritty paw or coat, and for the eyes as a gentle poured flush rather than a jet, and it is cheap enough that there is no reason not to have one by the door. It rinses; it does not treat, so pair it with a real vet visit for anything beyond mild, brief irritation.

Step 3: If They Must Go Out, Keep It Brief and Clean Them the Right Way
Sometimes a bathroom trip is unavoidable. Make it short, keep the dog leashed or supervised so it does not roll or dig in the ash, and then clean it in an order that matters.
Brush or wipe the dry ash off first, before you wet anything. This is the step people get backwards, and the reason is physical. Because ash is abrasive and does not dissolve in water, wetting a coat full of ash before you remove the bulk does not rinse it away. Instead the water works the ash into a gritty slurry that smears deeper into the skin and pads. IVHHN and Dr. Coburn both say to brush the pet before it comes back inside, so do that dry: brush or wipe the loose ash off the coat, legs, and paws first.
Then damp-wipe to pick up the fine residue. Once the bulk is off, a damp cloth over the coat and paws lifts the fine dust the brushing left behind, so the pet is not carrying it inside to lick off later. Wipe the paws thoroughly, since that is what goes straight into the mouth during grooming.
Check the pads and between the toes. The grit is sharp, so look for small cuts, redness, or embedded debris after any outing on ash. Rinse a gritty pad with saline or cool water rather than scrubbing it.
Keep the dog from licking ash off its own feet before you have wiped them, since that is the direct route to the gastrointestinal problems USGS lists among ash effects on animals.
A different hazard uses the same dry-before-wet order for a different reason. Federal guidance for a radiation emergency also has you brush a pet’s coat before washing it, though the agencies publish that step without the physical explanation IVHHN gives here; our radiation emergency shelter-in-place guide covers the fuller decontamination sequence, including the one thing that comes before the pet at all: cleaning yourself first.
Step 4: Flush the Eyes, Do Not Rub
Ash in the eye is the exposure most likely to cause an injury you cannot see, because the particles are angular and hard. Dr. Coburn’s instruction is specific and worth following to the letter: keep saline eyewash available, and only rinse, not rub. Rubbing, whether you do it or the pet paws at its own face, drags the grit across the cornea, which is precisely the corneal abrasion USGS names as an ash injury.
If you see ash irritation, flush the eye gently with pet saline or clean, cool water, letting it run over the surface rather than jetting it in. Then keep the pet from pawing at its face. If the eye stays painful, if the pet squints or holds it shut, or if you can see a scratch or cloudiness, that is a same-day veterinary visit. A scratched cornea is not something to manage at home; first response is where this guide ends and the vet takes over.
Step 5: The Food and Water Contamination Rule
Ash does not stop at the coat and paws. It settles on everything left out, including bowls, and swallowing it is its own hazard. IVHHN’s ashfall guidance is to keep animals’ food and water clean and, for household water, to let ash settle and then use the clear water. Alaska’s State Veterinarian recommends cleaning water dishes regularly and covering or storing feed. The same applies to your pet’s bowls.
The practical version:
Bring food and water bowls inside before and during ashfall, or cover them. An open bowl on the porch is an ash collector.
Pour from sealed, stored water rather than refilling from a bowl or a source that has been collecting fallout.
Keep food sealed and indoors. Ash on food is abrasive grit going into the digestive tract.
Honor any Do Not Drink notice for your pets too. If your area’s water supply is flagged during or after an eruption, use stored or bottled water for animals until the notice lifts, the same as you would for people.
This is where sealed water storage stops being a nice-to-have. During an ashfall, the difference between a clean bowl and a contaminated one is whether the water came from something with a lid on it.
Step 6: The Respiratory Watch
Even indoors and cleaned up, keep an eye on breathing, because inhaled ash is abrasive and can irritate the airways as it settles there. The AVMA’s list of smoke-and-particulate signs to watch for in pets covers ash exposure well: coughing or gagging, difficulty breathing including open-mouth breathing and increased noise when breathing, eye irritation and excessive watering, nasal discharge, and fatigue or weakness.
The AVMA’s rule on what to do is short: “If any of your animals are experiencing any of these signs, consult your veterinarian.” It also flags that “Animals with cardiovascular or respiratory disease are especially at risk from smoke and should be watched closely whenever air quality is poor”, so a pet with an existing heart or lung condition, a senior, or a flat-faced breed that already works to breathe deserves a lower threshold to call. Treat ash inhalation as a vet call, not a wait-and-see.
What About Masks and Goggles?
It is tempting to reach for a pet respirator or goggles when the sky is falling, but the state veterinarian’s caution here is worth heeding. Dr. Coburn advises against goggles, masks, or ear protection on pets that have not been trained to wear them, noting the unintended consequences of trying something drastically different on an already-stressed animal. A mask a panting dog fights, or a goggle it claws at, can cause more trouble than the brief exposure you were trying to prevent.
The gear she does endorse for ash is pet jackets and foot booties, which most animals tolerate, plus the saline eyewash. And the honest ceiling on pet respiratory masks generally is covered in our review of whether dog smoke masks actually work: the short version is that a seal a panting dog breaks is not the protection the packaging implies. For ash, the more reliable move is keeping the pet indoors during the heaviest fall and limiting outdoor time to brief, supervised trips.
Ashfall Pet Checklist
Keep pets indoors during the heaviest ashfall; limit outings to brief, leashed, supervised bathroom trips.
Seal the house: close doors and windows, damp towels at thresholds, tape draughty windows, shut down systems that pull in outside air.
After any outing, brush or wipe dry ash off first, then damp-wipe the coat and paws. Never wet a heavy ash coat before brushing it out.
Check paw pads and between the toes for cuts; rinse gritty pads with saline or cool water.
Flush ash from eyes with pet saline or clean water. Only rinse, never rub. Painful or squinting eye equals a same-day vet visit.
Bring in or cover food and water bowls; pour from sealed stored water; honor any Do Not Drink notice for pets too.
Watch breathing. Coughing, labored or noisy breathing, watering eyes, or nasal discharge means consult your veterinarian, sooner for pets with heart or lung conditions.
Do not dry-sweep tracked-in ash near pets; dampen or vacuum, and keep the pet out of the room.
Where This Fits in Your Plan
Volcanic ash is its own hazard, but it overlaps with gear and habits you may already have from other emergencies. The paw-protection and boot-acclimation work in our dog boots for wildfire ash and hot debris guide applies almost unchanged, since both hazards put abrasive material under your dog’s feet. When ash keeps a dog stuck inside for days, indoor enrichment for smoke days covers how to burn that pent-up energy without the outdoor exertion you cannot safely allow. And before you buy any pet respirator on the strength of an eruption headline, read our honest look at dog smoke masks so you know what that gear can and cannot do.
The best time to sort out sealed water, sized booties, and a can of saline is on an ordinary week, not while the ash is already falling. If you live downwind of a volcano, treat this the way coastal households treat hurricane season: the plan is only protection if it is in place before you need it.
Frequently asked questions
Is volcanic ash more dangerous to pets than wildfire smoke?
It is a genuinely different hazard, not a worse version of the same one. Wildfire smoke is mostly fine particulate that disperses as air quality improves. Volcanic ash is pulverized rock and glass. USGS states plainly that ash is hard, abrasive, mildly corrosive, and does not dissolve in water, and that it is not the soft product of combustion like burned wood. That means it physically abrades what it touches. USGS lists eye and skin irritation, respiratory discomfort, abrasion of the teeth, and gastrointestinal problems among the effects on animals. It also settles and lingers rather than clearing on its own, and stirring or sweeping it dry lifts it back into the air. So the smoke playbook of keep pets indoors and watch their breathing still applies, but ash adds a cutting and scratching problem to the breathing problem.
How do I clean volcanic ash off my dog or cat?
Brush the dry ash off first, before you wet anything and before the pet comes inside. IVHHN advises brushing pets before letting them indoors, and Alaska's State Veterinarian, Dr. Sarah Coburn, likewise recommends brushing the coat before entry. The reason to go dry first is physical: because ash is abrasive and does not dissolve in water, wetting it before you remove the bulk turns it into a gritty paste that you then grind across the skin and pads. So brush or wipe the loose dry ash off the coat, legs, and paws first, then follow with a damp cloth to pick up the fine residue. Check the paw pads and between the toes for cuts, since the grit is sharp. Do not let the pet lick ash off its own feet before you have wiped it down.
Should my pet wear goggles or a mask during volcanic ashfall?
Be careful here, and take it from the state veterinarian rather than a product page. Dr. Sarah Coburn, Alaska's State Veterinarian, warns against putting goggles, masks, or ear protection on a pet that has not been trained to wear them, citing the unintended consequences of a big routine change on an already-stressed animal. The gear she does endorse for ash is pet jackets and foot booties, which most animals tolerate more readily. More reliable than any mask is keeping the pet indoors during the heaviest ashfall and limiting outdoor time to brief, supervised trips. For the full breakdown, and why our answer on pet respiratory masks is a cautious one, see our smoke mask review.
Can my pet drink water or eat food that has ash on it?
No, treat ash-contaminated food and water as off limits. IVHHN's ashfall guidance is to keep animals' food and water clean, and its household water advice is that if ash gets into the supply, you let it settle and then use the clear water. Alaska's State Veterinarian, Dr. Sarah Coburn, recommends cleaning water dishes regularly and covering or storing feed. The same logic applies straight to pet bowls. Practically that means covering or bringing in outdoor water bowls before and during ashfall, keeping food sealed and indoors, and pouring from stored water rather than an open dish that has been collecting fallout. Ash is abrasive and mildly corrosive per USGS, and swallowing it contributes to the gastrointestinal problems USGS lists among ash effects on animals. If your area is under any Do Not Drink notice, that applies to your pets too, so use stored or bottled water until it lifts.
What are the signs my pet inhaled too much volcanic ash?
Watch for coughing or gagging, difficulty breathing including open-mouth breathing or noisy breathing, eye irritation and excessive watering, nasal discharge, and fatigue or weakness. Those are the smoke-and-particulate signs the AVMA tells owners to watch for, and it says if any of your animals are experiencing any of these signs, consult your veterinarian. The AVMA also flags that animals with cardiovascular or respiratory disease are especially at risk, so a pet with an existing heart or lung condition needs closer watching and a lower threshold to call. Ash inhalation is a call-your-vet situation, not a wait-and-see one, because the particles are abrasive and can irritate and scar the airways rather than just passing through.
Do dogs need booties for volcanic ash?
Booties help, and Alaska's State Veterinarian lists foot booties among the protective gear worth using for ash, alongside pet jackets. They keep the abrasive grit off the pads and reduce how much ash the dog tracks in and licks off. The catch is the same one that applies to any boot: a dog that has never worn them will kick them off, so they only help if you have fitted and acclimated the dog beforehand. If your dog will not tolerate boots in the time you have, the fallback is to keep outings brief and clean the paws thoroughly after each one. Our guide to dog boots for wildfire ash and hot debris covers how to fit and size boots and how to acclimate a dog to them, and the sole and fit lessons there carry straight over to volcanic ash.
