Collagen is a safe nutrient for your dog. Bovine collagen helps rebuild and keep your dog's joints feeling younger and pain-free. It also helps rebuild cartilage, something glucosamine can't do in normal joint chews.
 
Collagen helps keep your dog's skin moisturized, elastic, and healthy. In a few weeks you'll feel a softer, silky, and more petable coat for better cuddling time.
 
Collagen is very effective for animals suffering from osteo-arthritis to relieve pain and discomfort.
