Defective seam
Size: Large - 2 Count ( Pack of 1), Size: Large - 2 Count ( Pack of 1)
My dogs love these, defective or not. I have purchased the two ball set this is the 3rd and last time. Each set has had one ball with a defective seam on interior rubber ball which means it splits open on the first squeeze from the dogs.

I use these with the Chuck it launcher and they are great! My dog absolutely loves playing Chuck it and would play it until he dropped if I let him.

Good for small dogs
Size: Small - 2 Count (Pack of 1)
These are great for small dogs that have trouble getting their mouth around a regular size tennis ball. My only issue is that they are small enough to roll under things and I end up having to move furniture to find them. My dog loves them.
