When our pets are sick, they need extra care to help them recover quickly. Sometimes, particularly if they come down with an infection, they need to see a veterinarian, who may prescribe an antibiotic to quicken recovery time. Amoxicillin is among the most common antibiotics vets prescribe.

Amoxicillin is an antibiotic primarily prescribed to humans to treat bacterial infections. In some cases, veterinarians can prescribe this drug to cats and dogs.

In dogs, Amoxicillin can treat:

  • Bacterial infections
  • Urinary tract infections

Is Amoxicillin safe for dogs?

Yes, in some cases. Talk with your veterinarian about any medications your dog takes, as well as any current or past health conditions they’ve had. If you are worried about administering this drug to your dog, talk through potential benefits and risks with their veterinarian.

Dosage

Dosing will differ for each dog, based on their age, weight and other factors. Amoxicillin is also FDA-approved for veterinary use and typically comes in tablets, capsules and sometimes liquid. Always follow your vet’s instructions for dosing. 1-800-PetMeds outlines the general dosing guidelines for Amoxicillin for dogs:

  • 5-10mg per 1 pound of body weight every 12-24 hours

Please remember: this is just a general dosing guideline. Dosing may also differ for cats. All dosing inquiries should go directly to your pet’s veterinarian to ensure safety during treatment.
