Best play ball for small dog!
Color: Red/Yellow, Size: 2 in
Best play ball for a Jack Russel or any small dog that likes to play with a ball. The “teething like shape” give a good grip and my JR loves this ball.

Great rubber balls to stuff with treats!
Color: Blue/Green, Size: 2 in
Fast shipping, packaged well, nice size dog balls for small dogs. Plus, non toxic for dogs. I use these balls to put different soft small treats all through the gaps. My dog loves it. It keeps my dog entertained and happy for awhile when I leave. Great balls to put treats in. 5*****

Un chewable
Color: Blue/Green, Size: 2 in
I have two grand dogs, actually three but one of them can chew most balls apart in a matter of a couple of hours I bought these balls. They’re great because the dogs can easily pick them up. They’re a little smaller for the smaller dog. I wish they made larger ones. I haven’t seen them anyway, but this dog cannot chew this apart at all, so I don’t have to worry that they’re eating any rubber or plastic. I highly recommend them.

Very sturdy chew toy
Color: Bacon
My Frenchy loves it! He’s not a large dog, but big for a French Bulldog. (32 lbs). He chews both ends, but prefers the snout. The eyes are cute, but began to peel off within the first week. I easily removed what was peeling. Half of the paint remained intact. When necessary, I will definitely replace it with the same toy.
