Our dog loved these?!!
Color: 4 Color For XS/S 2.2", Size: Small
We have a miniature long haired Dachshund named Winston and OMG HE ABSOLUTELY LOVES THESE squeaky toys. I swear he must have played with them for 6 hours straight the first time we gave it to him. He love it so much that he even took it to bed with him that 1st night.
Many months later these are still his favorite toys. I think he likes the saucer-like shape of them & how they fit & feel in his mouth. The squeakers don't last very long but that's always been the case with squeaky toys & it doesn't seem to bother Winston much either.

My dog loves these
Color: 4 Colors For M/L 3.1", Size: Large
My dog absolutely goes crazy over these squeaky toys. They bounce all directions and he can entertain himself for a bit til I'm free. However, if your are trying to talk on phone or with family you might want to hide them for a while. Noisy. Lol

The Greatest Entertainment Toy Ever
OMG what toys, the best ever. Reasonable price, well made, safe, the noise level is low and my little Jade'n (Yorkie) loved them, mainly the blue and red. I order the small sizes and it was perfect for him. Jade'n loved it when l bounce them, plus it gives him a healthy exercise workout. I can't say love them to much as l do and the one important thing is they had no rubber or plastic smell and cleaning them up is a breeze. Jade'n chews alot of his toys up, but, the durability on these are fantastic as he hasn't been able to damage them and that to me is a well made toy. Love, love them.... thank you.....
