My Dog Is Losing His Hair On His Tail. There Is A Small Red Patch That Looks Irritated And Is Itchy. Is There Anything That I Can Do To Relieve The Itching.
I'm worried that it might be contagious. He hasn't had any change in his diet and nothing stressful has happened. He walks around with his tail between his legs. He is constantly licking the area. He is 2 years old. What can I do
