Other Causes. If your puppy or dog has not been properly vaccinated and begins to shiver, cough, run a fever or discharge mucus from his eyes and nose he may have distemper, a virus common in puppies and adolescent dogs.
Evaluation and Treatment. Heel pain can have many causes. If your heel hurts, see your primary care doctor or orthopaedic foot and ankle specialist right away to determine why and get treatment. Tell him or her exactly where you have pain and how long you've had it. Your doctor will examine your heel, looking and feeling for signs of tenderness and swelling.
Visit a foot doctor (podiatrist). Ingrown toenails that become infected should not be treated at home, which is true for most infected wounds. Visit a podiatrist, more commonly known as a foot doctor, to get treatment for your infection. If the infection and nail are bad enough, minor surgery may be required.
