Our 13 year old dog had been getting a bit wobbly on his back legs, and it was hard to watch. We tried a few different things before, but nothing really helped, so we even got him a little pram for when he got tired. After starting him on collagen about 6 weeks ago, nothing seemed to happen at first. Then around week 4, we began noticing a real change. He’s back to doing his longer walks again and the pram is just sitting in the garage now. It honestly feels a bit amazing. We’re already on our 2nd bag and plan to keep him on it for the long run.
