Ringworm
Ringworm is a fungus that grows and thrives in the outermost layer of skin, hair follicles, and the nails of affected dogs on rare occasions.
It is very contagious and can affect humans and other animals.
It is usually transmitted when a dog comes into touch with other ringworm-infected animals, especially in dog parks, kennels, and shelters.
The signs are pretty obvious-ringworm is typically characterized by circular skin lesions or patchy bald areas that glow under a black light.
In most circumstances, it's also rather simple to treat.
Your veterinarian will most likely prescribe antifungal shampoo or lotion for your dog; for more serious conditions, oral antifungals will be needed.
Ringworm can be transmitted from dogs to humans, so take extra precautions if you suspect your dog is affected.
Keep in mind that the illness typically takes roughly 100 days to clear.
The easiest approach to prevent ringworm in dogs is to clean your home and any grooming products or bedding that your pup may come into contact with regularly-especially if your dog is frequently around other animals.
