I got some of that neo predef powder for Tate at one point b/c he was having issues with his nose rope. I barely touched the stuff though b/c it was difficult for me to apply it and was a bit messy. That was the main drawback of the powder for me.
That is hard that Wally would need another surgery. Is that definite or will u seek another opinion? I know my vet was talking surgery for Tate too b/c of his excessive tearing in his rt eye but since he had that intestinal issue and i've cut way back on his treats, the tear stains have improved greatly so i'm hoping i can control it via diet and hygiene.
