This is our second one of these, which really speaks to how much my dog loves it… it’s cute and just the right size for my Vizsla. She absolutely loves playing with it… it’s chewable and has a nice squeaker, but I’m not so sure of its durability. Our first one lasted about a month, and this one just a couple of weeks. The stitching at the tip seems to give away first, then the find. Sadly, you gotta throw it away when you see the first signs of the stuffing.

Good quality for the price

More durable than others. We have an aggressive chewer so I know the squeaker will be destroyed eventually. The fact that it didn't get destroyed day 1 is a positive.

Go with tough rubber toys---you'll be ALOT happier!!!

This item isn't worth the thread used to make it. Only took my little puppy approx. 45 min. to gnaw the squeaker out!! The edging "tape" didn't last 1/2 that long. NOT good choice for tough teethers!!! I hand sewed damages---no help. For good toys---go with the KONG-type strength---REALLY TOUGH!!!
