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.

Deceptive Advertising
There's a little bit of false advertising going on here unless you thoroughly read the description. There are three balls in the picture, but you are only purchasing two. Always read the whole description before buying!
