Ringworm is a common ailment that affects dogs and people alike. It can cause unsightly lesions and discomfort. Puppies are more prone to developing the condition than older dogs, as most dogs build up natural immunities to it.

Cause
-
Ringworm is caused by a fungal infection. A variety of fungi can cause ringworm, including Microsporum canis, Microsporum gypseum and Trichophyton mentagrophytes.
Source
-
Ringworm can be transmitted to your puppy through direct contact with other infected animals or people, or through direct contact with the fungal spores. These spores can be found in grooming tools and kennels.
Risk
-
The spores that cause ringworm to develop have a long lifespan, and can live on contaminated surfaces for a long period of time. Your puppy can contract ringworm from a kennel or grooming tool even if it has not been touched by an infected animal recently.
Treatment
-
Since ringworm is caused by a fungus, a veterinarian will prescribe your puppy an antifungal medication. These are usually topical medications that you will apply to the infected area.
Duration of Treatment
-
Most lesions will clear up on their own within 4 months. If your puppy is placed on an antifungal treatment, the medication will need to be applied several times a day for 2 to 3 days.
