Could also be her dish. Went through it with Ellie, vet finally suggested changing her plastic dish to a stainless steel one. Her nose improved but changing it again to a ceramic serving bowl is what finally allowed her to heal. We have it again with Elke and it seems she was scraping it on the bowl to get the dry dog food. Adding no salt chicken broth has helped her alot, she ins't scraping her nose on the hard dry dog food like she was. See the vet to be sure, but you can also try changing her dinner dish. Elke likes her large, flat spaghetti bowl.
