Keeps pups busy!
Color: Fox-Crocodile
Great price for this item!! Makes puppies work for their treats and so cute. Squeaky and crinkly noises. Seems durable so far.

A favorite with my dogs but didn't last long
Color: Fox-Crocodile, Color: Fox-Crocodile
These have been a HUGE hit with my aggressive chewers but after less than 3 months, this is all that is left of the poor fox and alligator. My youngest STILL plays with them like they are brand new. I will probably buy them again but wish they were actually designed for aggressive chewers as advertised. I would say it's more for the average chewer. 4 stars because it was a good purchase and a top favorite toy but just didn't last long.

Too Cute!!!
Color: Fox-Crocodile, Color: Fox-Crocodile
This was a pleasant surprise and especially for the price!!! You get a 2 pack of toys!!!! They are absolutely adorable and made to last!!! Soft and lightweight!!! Has a nice squeakiness which my dog adores. I appreciate that they are made to fold up and Velcro so they become very compact. You can store them so easily and/or slide in your purse, traveling bag or leave one in your car. They fold up to be the size of folded socks. I recommend.

Our pup loves it (to pieces)!
Color: Fox-Crocodile
Fun toy for our playful pup, but nothing indestructible. She finds a seam and in days, the toy is in bits. Lucky for us, she still enjoys playing with parts! Package of 2. One down, one to go!

Holds Up Well
Color: Fox-Crocodile
My dog loves this toy and after several months of heavy use he has yet to rip it apart like he's done with every other toy I've bought him. He has a hard time grabbing it with his teeth to play his usual tug of war games.
