My dog's pyoderma is spreading and getting worse on antibiotics. What to do?

Updated On September 23rd, 2025

Pet's info: Dog | Pit Bull Terrier | Female | unspayed

Hello, Just wanted a second opinion regarding my dog's pyoderma. Started mostly on her legs and stomach a bit on her head. I believe the vet gave her a chlorhexidine bath on her first visit. As well as putting her on cephalexin medication twice daily for 10 days. She advised us to not bathe her until the next visit which is in 2 weeks. 4 days in it is all over her body even her mouth. The vet told me to wait since she's on antibiotics. There's crusty scabs forming And new pustules. What do I do?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! If new pustules are forming while Angel is ON antibiotics she should be seen again. I would get a second opinion if your Vet isn't responding to your concerns. Her infection shouldn't be spreading. I am also concerned that they are forming in her mouth or on her lips. It could be more immune medicated. I would consider culturing one of the pustules because the the bacteria is likely resistant to cephalexin. Hold on the bath until you see a different Vet. I hope this helps and I wish you and Angel a speedy recovery!
