Yes, fleas and ticks can significantly affect your dog's health. Fleas can cause itching, skin irritation, and allergic reactions. They can also lead to more severe skin infections and anemia, especially in young or small dogs. Fleas are also known to transmit tapeworms, which can further complicate your dog's health.

Ticks, on the other hand, can transmit serious diseases such as Lyme disease, Rocky Mountain spotted fever, and Ehrlichiosis. These diseases can lead to symptoms like fever, lethargy, joint pain, and in severe cases, can be life-threatening if not treated promptly.

To protect your dog, consider regular flea and tick prevention methods such as topical treatments, oral medications, or flea collars. Regular grooming and checking for fleas and ticks after walks, especially in wooded or grassy areas, is also essential. If you notice any signs of infestation or illness, consult your veterinarian immediately for appropriate treatment.
