Dog ticks are small, blood-sucking parasites that attach themselves to dogs and other animals. They belong to the arachnid family and can transmit various diseases, such as Lyme disease and Rocky Mountain spotted fever. Ticks are typically found in grassy or wooded areas and can latch onto a dog during outdoor activities. To prevent tick infestations, pet owners should regularly check their dogs for ticks, especially after walks in nature. Using tick prevention products, such as topical treatments or collars, can also help protect dogs from these pests. Keeping yards well-maintained can reduce tick populations around the home.
