So much sturdy fun for little dogs!
Size: Small 2"
Wow! My puppy loves these! He is entertained endlessly chasing after and nose scooting the little rubber balls! He really seems to enjoy the jingle sound and loves to chew on the balls also. Even with a lot of chewing from his little teeth, there are no marks. Sturdy, great toy!

Well made, perfect size!
Size: Small 2"
My dogs love these balls. They are the perfect size and hold up well for my 2 dogs, 7# and 9#. The bell is a nice change from the squeaky toys.

Durable, bouncy, not annoying like squeaky ball & our dogs LOVE them.
Size: Small 2"
Love these and my dogs love them to! Not nearly as noisy as a squeaky ball (thank goodness) and they bounce which are dogs love. They will fetch them, and they will play by tossing it up and pouncing on it when it bounces. They literally entertain themselves with it when we aren't playing fetch. Much more durable than the round rubber / latex squeaky ball / toys.

Quality item.
Size: Small 2"
These seem to be quality dog toys. I bought them for a friend's chihuahua. My cats were unimpressed, lol. The chihuahua had never seen a ball. He seemed curious, but would not approach this new item. Time will tell.
The bells have a very loud shrill sound, completely unlike any I've ever heard before.
