Small and squeaky!
Pretty perfect! Great size for small dog and they do squeak. It’s helpful to use both hands when getting the ball to squeak. It’s a bit difficult with just one hand, but that can’t be avoided because the size of the tennis ball is small. We use these inside and outside to exercise our puppy.

Milo approved!!!
Color: Multi-colored, Size: Large - 4 Pack
My dog, Milo, loves these squeeky balls. He is a larger dog but not huge. He's about 60 lbs. They are the perfect fit to his mouth. Soft enough for him to chew on but sturdy enough to hold up.

Squeaky Tennis Balls Are Great Fun!
Color: Multi-colored, Size: Large - 4 Pack
My Doberman loves these! That said, she doe's tear them up over time because once she gets one, she squeak's it continually and chews it. They are tennis ball which are not made to withstand aggressive chewers, but she loves them. They are a great size for her, we play with them every night. She's not a picker and doesn't swallow things so I let her have each one until it's destroyed. Then we get out another one to start the process again. They are a reasonable price for the fun she has.
