Hello! My dog started to lick each side of her nose in the middle of the night last night. Then I could hear her scratching herself. When I went to look, she scratched her chin till it was bleeding. I stayed up with her to stop her from making it worse. She is still licking the side of her face and trying to scratch her chin. She is also licking her front legs. Any ideas on what we can do to give her some relief. You can see her skin is irritated and raw. Thank you!
