Great value for the price
Style: White, Size: 24" Jumbo
I have gotten smaller versions of this Lamb chop, my dog has loved them all the same but this one is great. It's big enough for him to carry around and it lasts a lot longer since he likes to tear them up fast.

Durable.
These are great for my 13 lb Schnauzer. Just the right size to keep him occupied! He loves chasing after them when we play catch. They’ve held up well to his sharp teeth.

Durable yet soft ball that our dog enjoys chewing.
The balls are soft and well received by our puppy. They are pretty durable and he enjoys both chasing after them and teething on them.
