Is hydrogen peroxide safe for cleaning my dog's neuter incision?

Updated on September 23rd, 2025

Pet's info: Dog | Australian Shepherd | Male | neutered | 7 months and 30 days old | 45 lbs

My dog got neutered yesterday and they told me to clean the stitches with hydrogen peroxide once a day for the next 5 days. I've heard that it hinders the healing process and that it shouldn't be done. Should I clean the incisions with hydrogen peroxide?

You're right about that! I never tell any clients to clean any surgical site with hydrogen peroxide for that reason. If the surgery was performed under sterile circumstances, you should not have to clean the area with anything post-operatively other than maybe to remove some dried blood that may be adhering to the skin. Additionally, most practices nowadays do not place external sutures during surgeries like neuters. I would find out from your veterinarian why he is making this suggestion for Jax. Until then, I personally would not recommend placing peroxide on the area.
