Dog's neuter wound infected after peroxide, now vomiting. What's wrong?

Updated On September 23rd, 2025

Pet's info: Dog | German Shepherd | Male | neutered | 1 year and 6 months old | 66 lbs

I cleaned my dogs opened wound with Hydrogen peroxide. I just learned it's bad for dogs. What should I do? I cleaned DDs opened neutered wound. He's been throwing up since, I haven't feed him since yesterday. He's throwing up clear foamy spit up. First image is before I cleaned it and second is now. Is it infected?

Thanks for using Petco Pet Education Center, formerly Petcoach! It does look like it may be infected. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. They can flush it and clean it well and start him on antibiotics. He will get better on the right therapy. They can also examine him for possible causes of vomiting such as gastroenteritis and perhaps start him on something for nausea. Have a good night!
