Hair loss can also occur on other areas of their bodies.
Hair that remains is usually short and coarse. Redness and itchiness may develop. Some animals with ringworm will show no apparent lesions but can transmit the infection to others. Dr. Byrne explains that three types of ringworm are most commonly seen in dogs and cats. A few cats can be symptomatic carriers of M. canis.
