Can my dog eat asthma inhaler?
No.
A chewed asthma inhaler (Ventolin, salbutamol) fires the whole canister into the dog's mouth at once and sends the heart racing — go to a vet now, even if they seem fine.
Already ate it?
If they ate itGo to a vet now and take the inhaler with you. Don't make them vomit — it doesn't help with a punctured inhaler. Keep them calm and cool on the way.
Watch forFast breathing or panting, restlessness or unusual tiredness, a racing heart, vomiting, trembling, weakness — often within minutes of chewing the puffer. Treatment usually means a day or so in hospital.
Thinking of giving it?
Why not even a littleA standard Ventolin puffer holds 200 puffs of 100 micrograms — about 20 mg of salbutamol, released all at once when it's bitten through. No safe amount for a dog is published.
WhySalbutamol opens the airways in people but overstimulates a dog's heart, and once the canister is punctured the drug is absorbed almost instantly. It can also drop blood potassium, which brings weakness and dangerous heart rhythms.
