My puppy's favorite stick, high quality
Size: 5.75 inch (Pack of 1)
Perfect quality chew toy for my dachshund puppy. She will spend several minutes everyday chewing on this. It is the perfect size for her small mouth and it doesn't show signs of wear like most sticks do.

Durable
Size: 5.75 inch (Pack of 1), Size: 5.75 inch (Pack of 1)
Great buy would highly suggest for dogs that love to chew. I bout a large one for our 5 year old Husky and a medium one for our 11 week old puppy. Both are very intrigued by them and the puppy loves playing fetch with it. The only complaint I have is the size difference between the large and the small. I know measurements were given but the medium looks more like a very small stick. If you have a larger go with the Large size. Medium would really only work for smaller size dogs and pups

Hours of entertainment
Size: 5.75 inch (Pack of 1)
I lived this branch bone for my pups. They like to carry it around and chew on it for hours. Not only does it look cute when they walk around with the branch in their mouth but it keeps them entertained and no mess. Not heavy but I wouldn't suggest throwing it, it would still hurt a bit if it hits one of your shins 😅. Long lasting too
