I may have started a thread on this subject before but not sure. My son's Shih Tzu Barney just constantly scratches and constantly chews and licks until he has very irritated red bumps. This is at his backside above the base of his tail. I wash him in Head and Shoulders sensitive skin shampoo, it used to keep him clear but something is causing him problems. He has had a cortizone shot, cannot have another one, he is given a Loratadine 10mg every morning for the problem with allergies, on the place that is very irritated I use hydrocortisone spray which has always helped in the past but does not appear to be now. I have picked numerous fleas off of him over the past several weeks but I have only seen maybe 3 on him over the past week and look him over every day, wondering if all these places are flea bites or where he just chews. We have no answers to stop him from itching. I use Frontline on him once a month. Is this just a bad habit of his this chewing and licking of his I wonder. We hate to see him constantly irritated. Thanks.
