i have one crippled dog on previcox, flexadin and cani:feli artril (last one seems to have made most difference – has got all sorts of weird and wonderful stuff like devils claw, bears garlic, willow, fish cartilage, omega 3&6 – but when i tried conconcting it my own way didn’t work :-\ ) – that’s for severe knee arthritis.
other crippled dog with mysterious front legs, and back legs with spondylosis and disc problems is on low dose tramadol (third of what it was) and has just started plt – which actually seems to be kicking in.
but none of that is probably helpful because if it is tendon \ carpal tunnel type damage then it’s not arthritis based. in humans i think they use either steroid injections round the tendons or surgery – great aunt had carpal tunnel surgery. i would have thought physio\hydro\massage type things to keep it gently mobile would be more beneficial than drugs. :-\
