Thanks for the advice ladies! I've never given aspirin to my chi before, but I wanted something on hand on days when she seems a bit stiff. I usually have torbutrol from the vet but I've run out - I typically don't like to give this to her though, as it makes her very very sleepy.
I do supplement with glucosamine/chondroitin, but I can't tell if it's working or not. I give her Zuke's Hip Action. I have Glyco-Flex soft chews as well, which is a far superior product as far I can tell, but she flat out REFUSES to eat them. Any tips?
