unfortunately my boy has several severe orthopeadic problems & has been on metacam scince he was 6 months

& he will need it for life.
my query is has anybody else had a dog on metacm for this long a period.
i did ask my vets as i know the side effects, he has no gastro-intestinal problems on metacam, but i know it can effect the kidneys, however they were tested & found to be
100 % :) & my vet says that it is in dogs with impaired kidney function that it can cause a problem.
he has hydrotherapy twice weekly, acupuncture, synoquin & a bioflow collar so i am pretty sure i am doing all i can.
i am just worried about him being on drugs for the whole of his life,but i want him to have a good quality pain free comfortable life.
thanks
