Perfect for small dog that likes to chew
Size: Small, Color: Textured Ring
Just got this today (small size for my 15 lb dog) and she loves it. Perfect size for her small mouth and teeth. Keeps her busy and even tires her out and rests a while, Between this type of dog toys and ones that squeak she is having a great time

Great purchase!
Color: Red, Color: Red
I have 3 very different dogs, a Doberman, a rat terrier, and a German short hair - Great Pyrenees mix. They all LOVE these durable chew toys. I will definitely be purchasing more when the time comes. I wouldn’t need more due to durability but my rat terrier is an expert toy hider! 😅
