Ringworm is a skin infection caused by a fungus that attacks the dog’s claws, hair and skin. It spreads through direct contact with infected animals, or through contact with infected hairs or skin flakes on surfaces such as grooming equipment and bedding, or from the infected animal’s environment.
Your dog might have ringworm if it:
- Is only itching very mildly
- Is losing its fur in patches, often starting on the face and forelegs
- Has skin flaking
Some dogs, however, may have ringworm without showing any symptoms at all.
It’s possible for pet owners and their families to develop ringworm infection after handling an infected dog.
