So far my huge pit mix breed likes this to a lot and I’m surprised that he hasn’t been able to chew it up little bit of pb inside it and he’s focused for a good 20 minutes it almost fits on his foot too

Cute chew toy for smaller dogs!
Color: Red, Color: Red
Soooo my new puppy Dottie was continually eating my favorite pair of crocs by sneaking into my closet. To solve this issue I thought I would buy her her own chewy croc and actually found one on Amazon! lol The chew toy is actually heavy and weighted and the material is hard enough for an effective teething toy but soft enough for the puppy to play with! My little Weeney dog loved it the second I took it out of the package! The fake croc chew toy is a very cute design with a fun, bright color. The chew toy material is constructed of durable rubber and will last a long time. I didn't like that it doesn't make noise and is small.. I believe it is better suited for smaller breads to use which was perfect for my puppies needs.

You should have one on standby.
Color: Yellow, Color: Yellow
This product was great for my teething Bully puppy, she, is an aggressive chewer. It gave her relief and kept her busy. In the 6 or 7 weeks that we've had it, it stood the test of time. She would chew 10 or 15 minutes at a time and nap from exhaustion. Overall, several hours of chewing. I must say this toy is not indestructable. In the end it was necessary to remove it and substitute another toy. The bully on the picture looks like a twin of my own pup. I did remove loose slivers and pieces that could be chewed off immediately. I am attaching a pic of the pre-disposal remnants for clarity. This is a tough toy but again, not indestructible.
