Lyme disease is caused by a tick-borne bacteria that can cause lameness and inflammation of your dog’s joints. This disease can also cause neurological problems and kidney problems in severe cases. You may notice a stiff gait, difficulty breathing, fever and ever swollen lymph nodes. Lyme disease can be diagnosed through blood work. Since the symptoms are similar to those of other diseases, a clear diagnosis is needed. If your dog has Lyme disease, he will be treated with antibiotics and possibly anti-inflammatory medication. Lyme disease is often transmitted by deer ticks and the infection has been discovered in all 50 states of the United States. The best course of action is to prevent tick bites in the first place. Use a monthly tick preventive medication all year round and check your dog for evidence of tick bites regularly. Learn more from your Plano, TX veterinary clinic.
