Wondered if anyone had ever had meloxicam or metacam cause sores on their dogs?
About a month after being put on Metacam Otro started to get two sores on his lower lips. At first I thought it was just doggie pimples and just made sure and wipe them clean often and even put a bit of neosporin ointment on them. They were not clearing up so I spoke to the vet clinic about them. They reccomended that I use a spray ( I cannot remember the name now

) that I had for our other dog, that was used to treat the sores that he licked onto his back from allergies. I did use this spray for several weeks but the sores have still not cleared up. They are still there. They seem to get a bit worse and then clear up a bit, but never go away. They ooze just a bit but not a whole lot.
Just recently I noticed a small discoloration on his nose. It has now progressed into a sore on both sides of his nose. There doesn't appear to be a discharge from them but he does lick them a bit so it is a bit hard to tell for sure. They are just red sores.
Has anyone ever had this happen with their dogs while on meloxicam/metacam?
I do have a vet appointment for Otro next week. We will be changing his medication then and I will be asking about these sores. But I just thought I'd ask on here in the meantime. Impatient me wants to get some info sooner
