How much amoxicillin for a chihuahua after pyometra surgery?

Updated on September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | spayed | 7.5 lbs

How much amoxicillan can I give a 7 1/2 chihuahua? She was treated at animal control today for pyometra when they opened her up to be spayed. They recommended course of antibiotics, but weren't specific about how much or how long. She is in a rescue shelter and we have the drugs, just don't know how much to give her.

Without a legal relationship, which in most states means that a physical examination has been performed on the pet, we cannot recommend specific drugs and dosages. I would recommend calling the vet who performed the surgery back and requesting guidance. I would also comment that amoxicillin is not a very good choice for post-op treatment of pyometra, and Gina needs something more broad-spectrum such as Clavamox or Baytril for at least 14 days.
