what nsaid did they use metacam, rimadyl? as those can cause a prob with the kidneys and may be why the concern? just trying to understand more of what is happening but nsaids can affect the liver and kidneys so you have to be really careful with those drugs and i avoid them after my dog was so sick on metacam due to her being on temarilp and vet gave on empty stomach so both were a huge no no and i knew it and asked for tramadol when she hurt her leg but the vet would not listen to me and pressured me into metacam and it was a 2 month nightmare and actually still dealing with it as she has bouts of colitis from time to time still and it has been since february so needless to say we will not be going back to him
