Great chew toy
Color: Blue
I bought this almost a year go. My dog is still chewing on it! Nothing last this long with her. She is a 100lb Rottweiler that is a strong chewer.

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.

Happy hound!
Color: Yellow, Color: Yellow
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
