Ticks can spread diseases including Lyme disease, ehrlichiosis and anaplasmosis to dogs and cats, and some of these also affect people. The Companion Animal Parasite Council notes that Lyme bacteria usually need 24 to 48 hours of feeding to transmit, so prompt removal makes a real difference.
Check your pet after every walk in long grass, woodland or brush, running your fingers through the coat and paying attention to the head, ears, neck, armpits, groin and between the toes. A tick feels like a small, hard bump.
