My dog has allergies and licks small raw spots on his paws. How do I stop him from doing this? Or how can I reduce itchiness? I give him benadryl everyday when he has a flare up but he wont stop licking his paw so it's not healing. Any tips? I think I'm going to buy some vetrap today and give him a bath with some anti itch shampoo and lotion I got from my previous vet.
