White spots on my new 3-month-old puppy's skin. What should I do?

There are several reasons this can occur. Try washing Henry with an antibacterial dog shampoo once a week. If this doesn’t help after a couple weeks or if it gets worse, have him seen by his veterinarian to check for skin mites, fungal infections (some of which humans can get) or allergies. Of course you don’t have to wait and you can have Henry checked at any point. I hope this is helpful and please feel free to post any additional questions.

Thanks for using Petco Pet Education Center, formerly Petcoach! Thanks for also adding photos. Since I can’t see Prince McArthur up close I can’t for sure but it is possible he has microscopic mites. These mites are not itchy and not contagious but can cause hair loss especially in young puppies. I recommend taking him to a vet so they can look with a microscope and get him treatment if necessary. Good luck and kisses to Prince McArthur!

Pitbulls are known for having allergy issues but I have not seen them show up in one quite so young. Without a photo it is hard for me to comment too much as to what may be going on. At 3-1/2 months old he will be due for vaccines again soon so I suggest you just monitor and bring this up at the next vet exam. In the meantime I would use this shampoo on him to see if you can relieve some of the itch. https://www.walmart.com/ip/SynergyLabs-Veterinary-Formula-Clinical-Care-Hot-Spot-amp-Itch-Relief-Medicated-Shampoo-for-Dogs-and-Cats-16-fl-oz/244249833 Hope this helps.

This may be a skin infection, possibly related to mites. For certain I would recommend to test it and have it checked by your local vet and possibly treat it before adopting her, especially if you have other dogs in the house.

I would have this checked by a vet. It sounds very much like ringworm. Although the name suggests otherwise, ringworm is not caused by a worm at all-but a fungus. This highly contagious infection can lead to patchy areas of hair loss on a pet, and can spread to other animals-and to humans, too. Classic symptoms of ringworm include lesions that typically appear on a pet’s head, ears, paws and forelimbs. These lesions can cause patchy, crusted circular “bald spots” that sometimes look red in the center. In mild cases of ringworm, there may be just a few broken hairs, while bad cases of ringworm can spread over most of a pet’s body. It’s also possible for a pet to carry the fungus and not show any symptoms whatsoever. Treatment of ringworm depends on the severity of the infection. A veterinarian may prescribe a medicated shampoo or ointment that contains miconazole or a dip such as lime sulfur to kill the fungus. In some cases, oral medications are necessary to cure ringworm. In severe cases, it may be necessary to use a topical and oral treatment, in addition to clipping away the fur. Once treatment begins, lesions should begin to heal in about one to three weeks. Please note, it is important to treat your pet for as long as recommended by your veterinarian. Even though the skin lesions may have cleared up, this doesn’t mean your pet is cured or can’t infect another animal or person. Certain diagnostic tests may need to be repeated in order to ensure cure. And unfortunately, there is no guarantee that reinfection won’t occur!

Thank you for submitting your question regarding Jack. I recommend that he sees a veterinarian. Skin tests will likely need to be performed. Demodex is a mite that lives normally in the hair follicles of dogs. Puppies can experience an overgrowth. This is common in his breed. The veterinarian can diagnose this condition with a procedure known as a skin scrapes. Of course, there can be other conditions affecting his skin. In the meantime, I recommend bathing him with a moisturizing shampoo and conditioner such as an oatmeal or fatty acid based formula to soothe the skin. Place an E-collar on him if he is licking or biting the areas. I hope this information helps!

If looks like he has a dermatitis which could be from a bacterial infection, fungal infection, or possibly mites. He should be examined by a vet to determine the cause. Your vet may need to do a skin scrape, culture, or cytology to help determine the exact cause. Once diagnosed, the appropriate medication can be prescribed. I don’t think this problem is secondary to the heat. Good luck with your new puppy.
