Has anyone heard of / used the above? Is it any good? Thanks in advance.

I use riaflex glucosamine and msm for my dogs and my 10 yr old cavalier can still run around an agility course like a spring lamb.There are several products in the riaflex range such as green lipped mussel and the one I use.

I just stocked up when I was at discover dogs on Saturday as some of the range was on special offer. The ingredients are of stronger strength than most other products on the market and work out very cost effective.

Many thanks ) was asking or a friend so I'll pass the info on .
