My dog is 10 years old, a collie mix. Suddenly his lips are changing colour and they look pink and swollen. As well, the left side of his nose is dry/white. He is constantly licking.
I took him to the vet and they prescribed some antibiotics, without really giving me a diagnosis or explanation. However, now that the antibiotics are finished the issue seems to be back.
Before I head back to the vet I just wanted to see if anyone else has experienced anything similar with their dog.
Thanks,!
