My ten-year-old dog gnaws occasionally on places on his front legs that end up looking bare of hair and inflamed. How do I treat that?

Dogs chew on themselves because they itch, either from fleas, allergies, or even a habit formed by anxiety or boredom. That means flea preventatives, and allergy and anxiety medications can help some dogs. But dogs itch so much, there is now a new monthly- injectable that stops their itch for up to a month. Talk to your veterinarian about it.
Regardless of the reason, you will need to treat the hot spots – the irritated skin lesions that result from repetitive biting, chewing, licking and scratching. You can find hydrocortisone sprays and other healing creams online and at pet stores. If that doesn’t work, your veterinarian can prescribe something stronger.
