Great tug-of-war toy
My golden retriever loves playing tug-of-war so this is the perfect toy for us. We’ve already played several spirited games (he has won all of them, by the way) and the toy is still intact. Great price for two toys!

Good choice for medium size dogs
My friend’s two dogs loved these toys. They got the tug-of-war part immediately! Not real loud which is a plus. Seem pretty sturdy!!!

Good material, terrible cheap squeaker
Nice plush toy that holds up well for tugging play but Daisy ruined the squeaker almost immediately; must have been very thin/cheap, she's just a small dog with smaller teeth.

Indestructible!!!
My puppy loves these toys and she hasn't chewed through them. That is a major win and shows how durable they are.

Not durable at all.
Not durable. My cocker spaniel puppy shredded the ropes in no time. They're cute, and for that I'd give a star, but cute does not support the point of having it. Would not recommend and would not buy again.
