Teeny Tiny Terrific Toy
Size: Extra Small (Pack of 1), Color: Pink
Perfect for a mini puppy! So teeny tiny; it cracks me up looking at it!! However, my little dog (10 week old Cavapoo) absolutely loves playing with it! It’s her fav! You can stuff 2-5 tiny treats in it to keep puppy occupied and focused.

Must have for a young puppy
Size: Small (Pack of 1), Color: Blue
Very helpful for our young puppy. Cleaning it isn't the easiest, but cleaning advice is easily found online and it's worth the hassle to have a durable lasting toy around

A favorite for my boys!
Color: Hambone Super Chewer, Size: M/L
My dogs love this toy, it satisfied their need to rip up a toy and still allowed them to play long after the top layer was torn apart to enjoy! It bounces well and has still held up with my chewers, this is still one of my dogs favorite toys to play fetch with!

Great toy
Color: Hambone Super Chewer, Size: M/L
My dog loves this toy so much. He's not quite so aggressive with his chewing, now that he's getting older, but this toy lasted through his younger years, and recently started to show signs of wear. He was so sad when I threw it out, that I had to replace it. Glad it still exists - we got the first one probably 5 years ago.

Great for heavy chewers
Color: Hambone Super Chewer, Size: M/L
Our dog is a hard core chewer! This toy is very durable. Even the covering has lasted. We assumed we would need to take the cover off right away but it’s still going after 3 months. It’s definitely chew resistant
