HI, I am Spike's Mom, an almost 13 yr old Westie. You may have seen my posts here.
Spike was diagnosed end of December last yr. He has a 2.5 cm mass -tcc in the bladder. We have had some real problems with severe diahrea with the peroxicam and we had to stop his treatment for about a week til his tummy settled down. We realized that he was spitting out his stomach pills too. Spike has always had a sensitive tummy so it was really tough for him. His incontinence got worse off the peroxicam and we were really worried. Once his stools got back to normal last Wednesday we restarted the peroxicam with Hills I/D diet and generous helpings of white rice twice a day along with his stomach meds embedded right into the wet food!!! So far, so good. He occasionally, maybe once/day pees in the kitchen now when my husband has to leave him in the kitchen in "dog jail" if he goes out but we think its also due to his not liking to be gated (you know Westies!! :) He is due for a repeat ultrasound in a month's time and if the tumor shrinks a little the specialist thinks we may be able to get it out (this of course is not a cure and we need to think about putting him thru the surgery). He like Betty is very frisky, puppy like and loves to run on his walks. We asked our Vet about metacam and she had heard of it but was not that familiar with it, but I've seen on posts other people trying it. The specialist we took Spike to who did the scope and biopsy also recommended peroxicam but we will see how Spike tolerates it now with rice to bind him and the stomach meds in him. I don't know if this helps you at all but if you can use any of this advice that would be great!!!

PS to anyone who has put your dog thru surgery, how did it work out?
