Strong hold
Color: Multi-colored, Color: Multi-colored
Very good product. I’m definitely impressed. I have two German shepherds and this toy is definitely durable and does what it’s made to do. The suction is great. The company even gives you a clear plastic strip that you can actually put on the floor and then put the suction cup on it For better grip. I’ve had suction toys before which was absolutely horrible. This one definitely supersedes all others. The suction comes off once in a while but usually that’s because if my dogs are literally biting on the suction cup part lol. But with confidence. Great product

Base of you is very durable
Color: Blue
Overall this is a fun toy. My German Shepherd loves it. The ropes were chewed off within the first hour which was disappointing. Using it for treats did not work because the opening is so large. It has become only a chew toy and it is very durable. Since I bought this to enjoy the extra features, I am disappointed. I was able to buy three chew only toys for the same price. I still give it four stars because my dog likes it so much.

The dog will destroy the ropes and eat them be careful with this
Color: Blue
The rubber part is very durable but the strings or ropes are not. Puppy is eating the strings and having a hard time pooping them out. Just cut them off close to the knots and watch for them to eat the strings they pull off.

Is not as durable as they say for large dogs
Color: Multi-colored
My dog loved the fact he got a new toy and he loved the toy itself. Carrying it around and shaking it, that is. The ropes are small and pop right back out of the ball. They are more for a small dog to tug on. The suction is strong but still not strong enough for a 100 lbs Rotti. He kept grabbing the eleasic ropes and pulling off the floor.
