My 2 yr old bloodhound destroys every toy in minutes, but not this one. My husband and I actually buy toys to see how long they last for fun. Although the croc is NOT indestructible, it lasts a whole lot longer than most. After an hr or so, I took away the only piece he's chewed off which is part of the back leg. Otherwise nothing else is missing off the croc. Our boy has been very occupied with this new toy and we're satisfied with his new distraction!

Definitely a tough toy

Color: Blue

This is one of the few toys my Boxer/american bulldog mix hasn’t been able to tear apart. He loves chewing on it and I love that he doesn’t chew on stuff he shouldn’t. I have such an issue with toys being torn apart the day I bring them home. I wish there was a safe way for it to have a squeaker since he loves squeakers but I don’t think that is possible.

Croc-sational

Color: Blue

My tough chewer is OBSESSED with Croc. Stands up well, small particles occasionally come off but this beats going thru 3 stuffies in an hour. Good value, easy to clean and great for our 91lb pitty

Withstands very aggressive chewing

Color: Blue

We have a very active and aggressive chewer. Items identified for aggressive chewers are “Gone in 60 Seconds”. This toy is amazing. It has withstood Jake’s many attempts to destroy it and is one of his favorites! It is not hard like acrylic but is hard rubber with some give decreasing risk of fractured teeth. Best toy yet!!!

Well loved

Color: Blue, Color: Blue

We just got this sweet girl from the shelter a few days ago. She's had this toy for 2 days and already chomped off one of the legs. She does have other toys so she doesn't play with this one all the time but she does like it a lot! It's very hard and durable on the ends. But as you can see, it's not indestructible. She carries this little guy around the house like they're BFFs. It's super adorable.
