Puppy ringworm: How long until bald spots heal and hair regrows?

Updated On September 23rd, 2025

Pet's info: Dog | Vizsla | Female | spayed | 4 months and 18 days old | 63 lbs

My puppy has a fungal infection (doctor says most likely ringworm) we have been treating it with topical cream and shampoo for 6 days now. In how many days/weeks should her bald spots regrow hair and her lesions (red lumps) heal and disappear? Do you think her skin will look back to normal in 2weeks? Or 3 weeks? Thankyou

Ringworm can take up to 3 months to go away. I think this article will explain more. ( https://www.petcoach.co/dog/condition/ringworm-1/ ) Was she tested for ringworm or is your vet just guessing that is the problem? The reason I ask is because it actually looks more like mange lesions to me. If you are not seeing much improvement after another 7-10 days and your vet did not actually test for ringworm, then I suggest you have her back to your vet to talk about actually testing for ringworm and testing for mange to get this figured out.

    Because the hair takes 6weeks or so to grow back, the only way to be sure is to get her retested. 2 week is quite a short period for treating a fungal infection such as ringworm and it may need to be extended if still positive
