My dog loves these! She has a small mouth and not many balls fit in her mouth when we play fetch. The only thing is that she can't make the balls squeak on her own, it does take pressure. However, maybe that's a plus if you don't wanna listen to squeezing all day haha. They are durable, very bouncy even in the dirt. Great price fun toy!

My dog loves them...but

Size: Small

The ball is firm, durable and bounces well, but the squeaker is a disappointment. My 16 lb chihuahua doxie mix is obsessed with squeaky toys. I bought the small size which is a good fit. These balls are a bit firm and hard to squeak but she is still able to squeak them endlessly. The squeaker only lasts a couple of weeks then it's just a ball that she ignores.

Best Balls Ever!!!

Size: Medium

These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!
