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!
Color: blue
Quality is great! They were bigger than I expected too. My heavy/aggressive chewers haven’t made a tear in them at all and it’s been a day! IYKYK Highly recommended.
