How to treat ringworm in multiple pets and stop it from spreading?

Updated On September 23rd, 2025

Hi. I just brought a new kitten into my home and I believe it's carrying ringworm. It still needs a dewormer. Which product to you recommend. Also the reason I believe the kitten is a carrier is because my dog has a lesion on his snout and my adult cat has a lesion on his leg. Also my 10 yr old nephew has a few lesions which he has seen a doctor for. My question is which is the best way to treat all of my animals so this will stop spreading and coming back.

You are correct that ringworm is very contagious, and it can be given to both humans and other animals. All the animals the home have to be treated with anti-fungals (either oral or topical) in order to cure it, and your home will have to be disinfected. Ringworm spores can live up to 18 months in the home, so it's very important to clean your house. I would take your kitten, dog, and cat into the vet for an exam. The vet can diagnose ringworm, and will prescribe anti-fungal medication to treat it. OTC ringworm treatments will not work as well as the medication that your vet can prescribe, and you won't get the best results and will likely still be dealing with lesions. I will attach a link to a website that gives details on how to disinfect your home: http://www.livestrong.com/article/49666-rid-home-ringworm/ As for the deworming treatment for your kitten, I recommend Drontal. You can get that from your vet when you bring the kitten in for ringworm treatment.
