**Fleas:**
1. **Irritation and Allergies:** Flea bites can cause intense itching and irritation. Some dogs may develop flea allergy dermatitis (FAD), which is an allergic reaction to flea saliva, leading to severe itching, redness, and skin infections.
2. **Anemia:** In severe infestations, fleas can consume a significant amount of blood, leading to anemia, especially in puppies or small breeds. Symptoms include lethargy, weakness, and pale gums.
3. **Tapeworms:** Fleas can carry tapeworm larvae, and if a dog ingests a flea while grooming, it can become infected with tapeworms, leading to digestive issues.
**Ticks:**
1. **Disease Transmission:** Ticks are known vectors for several serious diseases, including Lyme disease, Rocky Mountain spotted fever, and ehrlichiosis. These diseases can cause symptoms like fever, joint pain, lethargy, and in severe cases, can be life-threatening.
2. **Local Irritation:** A tick bite can cause local irritation and inflammation at the site of attachment, which may lead to secondary infections if not properly managed.
3. **Anemia:** Similar to fleas, a heavy tick infestation can also lead to anemia in dogs due to blood loss.
**Prevention and Treatment:** It is crucial to regularly check your dog for fleas and ticks, especially after outdoor activities. Use veterinarian-recommended flea and tick preventatives, which can come in the form of topical treatments, oral medications, or collars. Regular grooming and maintaining a clean living environment can also help reduce the risk of infestations. If you suspect your dog has fleas or ticks, consult your veterinarian for appropriate treatment options.
