My 10 year old Lab mix has been itching like crazy lately! She takes 5 steps, stops, and ITCHES! She ripped out 2 of her whiskers off of one side of her face, and now there are 2 big bloody holes on the right side of her face. She also ripped a chunk of skin off right above her eye. Yesterday I noticed 2 quarter sized scabs in the same spot on her right and left sides under her ribs. I put Neosporin on her cuts, but she licked it off and rubbed it on the carpet.
She also itches near her ears quite a lot. She has always chewed on her paws until they became raw and sore, but lately it seems to have increased. I was kind of worried about her, so I gave her a bath with oatmeal shampoo yesterday and trimmed and filed her toenails. I thought that would help her, but she seems to be itching even worse now.
My other dog does not have any of these problems, except for the occasional itch from a bug or whatever. They get Advantage flea meds every month. I recently switched them from Purina Dog Chow (which is supposed to cause allergies) to Blue Buffalo 2 or 3 weeks ago. I think the itching was already happening before that though.
What could possibly be causing this? We are worried the cuts will get infected. Please help!
