Bought these for gifts. One dog was squeaking it constantly (beware your ears lol) and within about 15mins it no longer squeaked. It was a Bernedoodle so wasn’t destroying it, just happily making it squeak. It still works as a bouncy ball. But the squeaker definitely doesn’t last long depending on how much it’s used. Overall a cute concept providing plenty of entertainment. Definitely not a toy if you have an aggressive chewer unless monitoring play.

DOGS LOVE

Size: 1 Count (Pack of 1), Style: Heart

My dogs love it! I buy as gifts too as it’s always appreciated. Easy squeak and fun to bounce with all the sides. My dogs chew until they crack & still squeak for a bit. When eventually squeak stops my dogs still return to it. They seem to love just for the air sounds. I personally appreciates that more than the squeak but what do I know? I’m not a dog.6

Great, but they don't last.

Size: 1 Count (Pack of 1), Style: Heart

Our dog absolutely loves these things. However, they get punctured or form a crack on a seam with very little use. This time it only took a couple of hours of play. Once this happens, they no longer squeak. This may sound weird, but the heart shape seems worse for this defect.

My dog loves it - yours will, too

My little merle bulldog absolutely LOVES this toy! It is so cute to watch him play, chew, and toss it all around. We were worried he would chew through the material but so far that is not the case. This product is sturdy and can take a beating!
