SafeFit™ Collagen Sticks from Bow Wow Labs are a smart way to make dogs happy because they promote both mental and physical wellness. While dogs chew, these all-natural, single ingredient sticks provide healthy mental stimulation and support for: Joint Health: Collagen is a vital component of connective tissues, such as cartilage, which cushions and supports joints. Enjoying collagen treats may help support joint health, reduce joint pain and improve mobility. Digestive Health: Collagen contains amino acids, such as glycine and glutamine, that support the integrity and health of the gut lining. Giving collagen sticks can help improve digestion, reduce gut inflammation and support a healthy microbiome. Bone Health: Collagen is an essential component of bones, providing structural support and strength. Treating with collagen may help support bone density, prevent bone loss and promote overall bone health. Oral Health: Collagen sticks can help reduce the buildup of plaque and tartar, promoting healthier teeth and gums with every bite. Our SafeFit™ Collagen Sticks are sourced from South American cattle, where the production is more sustainable and the beef is of higher quality. Plus, because they’re from Bow Wow Labs, our collagen sticks are sized to fit snugly in the Bow Wow Buddy® Safety Device, which promotes safe chewing and helps prevent choking. Thick sticks fit best in a Small or Medium Bow Wow Buddy® and Jumbo sticks fit best in a Medium or Large Bow Wow Buddy®.
