Ok so I'm very inexperienced when it comes to joint health, I'm calling my vet tomorrow but I wanted to see if you all could give me some helpful tips. So I have a 13 year old ex pleasure horse mare. She's not showing any signs of discomfort other than the occasional popping of her back legs. I'm wanting to know about a good supplement I can put her on. I'm leaning toward smartpak because I've heard good things about it. I also thought about Fluid Flex or Reasons 3 but I don't really want to put her on 30 different supplements. Being that she is a ex pleasure horse I'm sure she was injected. Does anyone have any tips for that? Will that be arthitis?
