After doing so much research it became apparent to us that enzyme therapy is one of the best dog arthritis treatment options. We’ve now been using Lifespan for 3 months and both of our dogs are doing so much better! We had to carry our older dog outside to go to the bathroom and he yelped often when he tried to move. After a few weeks on Lifespan he was moving slowly on his own and making outside. Now he is walking much easier and no longer in pain. We could not be happier with your products and support!
