This is a great product. My Aussie mix won't chase regular balls, but will chase these for long periods of time. Its the only way I can get him excercise right now. He holds them in his mouth constantly and has lost interest in his kong stuffed toys. This is my second time buying. The first time was great but the second batch had hardly any sqeak and not much air. Seller- please check your quality control! I have to go to another seller if these aren't consistent, because my dog needs the squeak in order to be interested.

These have become my two Shih Tzu’s favorite toys. They love playing fetch with them. Very durable and well made. Will buy again once these wear out.

Dog's BFF

Color: Burger Shape Assorted Color, Size: Small

My 10lb pup LOVES these toys. This is the second set I've bought. First set lasted 5 years. The squeaker can be a little irritating after awhile. But that's what he loves. Great toy for my little guy!
