A friend has recommended this for our boy with osteoarthritis, has anyone tried it & what are your thoughts?

Not much help yet but I've just started my dog on it so would also be interested in people's experiences (and of course I will let you know mine). It works out pretty cheap for me as the 500g bag should last nearly 4 months.

My dogs have been on joint aid for about 3years.my boy pug was limping on and off he would run around jumping and leaping about then be lame next day I had him ex rayed and he's got very slight HD so put him on joint aid and touch wood never had a problem since. I took in a pug girl aged 5 she walks with stiff back legs although very lively I put her on joint aid about a year later I run out of it and didn't buy it for a while my girl started to have trouble jumping on the sofa was waiting for me to lift her up then I realised she hadn't had the joint aid for a while so started buying it again she was soon back to her old self again very lively pug she's now 8 so all mine have it now. I did recommend it to a friend who's elderly border collie was limping so she tried it and was very pleased with the results. Hope your dog does well on it also.
