I have a five year old lab mix. She has been getting nice size bumps on her nose, she sneezes constantly. The bumps kinda come and go, and change spots (for ex. One was up close to eye, now she has one on other side of nose, closer to end of nose).
I've taken her to the vet several times and after hundreds of dollars, they still aren't able to tell me what's wrong. I've given her benadryl, but without much result. Do you think I could give her some nasal spray? PLEASE HELP!!!
