My dog LOVES these balls
Awesome balls! Soft, squishy, and dog can get their teeth into them but they don’t get damaged. My dog absolutely loves them!

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.
