Fantastic toy for strong chewers
Color: Green
This dog toy is FANTASTIC! I have a pitbull that is a STRONG chewer and not even a piece has come off! This toy has lasted the longest of any dog toy I’ve ever had! I got one and then immediately ordered another one! Highly recommend

Maybe for XL breeds.
Color: Green
This pull toy is too heavy for my 49 lbs Foxhound/Beagle mix. The “beads” are very sharp, and he didn’t want to put it in his mouth to chew on or play tag. I don’t think he’s picked it up since the first time I gave it to him. Extra large dogs may love it, but it was just too large and heavy for my dog. He was very unhappy with it.

Very sturdy toy
Color: Blue
It’s very sturdy and has a surface and handle that allows a dog to grip on for a good tug. It’s also holding up to my very, very aggressive chewer and she’s 80-90 lbs.
