Is Amoxicillin-clavulanate (Augmentin) Safe for Dogs?
Why it’s a problem
The clavulanate in Augmentin adds to the stomach irritation that amoxicillin can cause, so vomiting and diarrhea are common after a dog eats human tablets. Dogs frequently swallow several pills at once because chewable forms taste pleasant. Serious toxicity is uncommon, though very large ingestions can cause dehydration from repeated vomiting.
How to keep your pet safe
Keep Augmentin out of reach and never self-dose your dog with human antibiotics. If an infection is suspected, a vet needs to choose the drug, dose, and duration.
Warning signs to watch for
Drooling, nausea, vomiting, diarrhea, loss of appetite, belly discomfort; heavy ingestions can lead to dehydration and marked lethargy.
When to call the vet
Call your vet or a pet poison hotline with the number of tablets and the strength. Watch for repeated vomiting over the next day and seek care if it continues.
Common questions
My dog ate three Augmentin tablets — what should I do?
Call your vet or a pet poison hotline with the tablet strength and your dog’s weight. Most dogs get an upset stomach, but the amount swallowed determines whether monitoring at home is enough.
Can Augmentin hurt my dog’s kidneys or liver?
Single accidental doses rarely cause organ damage, with stomach upset being the typical effect. Very large or repeated ingestions are a different story and should always be assessed professionally.
Can I split my Augmentin prescription for my dog’s skin infection?
No. Human tablets are not dosed for dogs, and treating without a diagnosis can hide a worse problem. Ask your vet for a proper prescription.
