Great for toy destroyers!
Color: blue
Got a destructive dog?
These are the best toys ever! Our girl gets at least a week or sometimes 2 out of each toy. She can destroy a typical dog toy in under 30 min. She loves these!!
BIG PLUS.... no fluff to clean up!!!!

Great for heavy chewers!

Plastic stuffing in it
Color: blue
I was concerned when I started finding little pieces of plastic wrap around my house. Where did it come from, I wondered? When my puppy is shark “no stuffing” toy to me, I found the source! The fin he ripped off that crinkled was full of little plastic pieces of plastic wrap. And it was all over the houses.
