We have seen a remarkable improvement in our 12 year old dog since we started using this product. She was limping a lot and had very little energy, and now she is like her old self, and she doesn't limp as much anymore when she walks. This is powerful stuff, and I HIGHLY recommend it for your pet.
Four days after I started my aging Sheltie on NatuVet Glucosamine DS, I noticed he was acting like a puppy and wanted to play with his two "Chihuahua" siblings that share our home. He runs and has more energy then he's had the past few years.
