Didn’t Last
Color: Blue
Cute toy and was fun for either quiet play or rowdy play. It didn’t last as long as I expected but it was fun for a while.

Great tug toy

Great size for dogs 50-58 lbs to play tug with. Well made, bright colors, and easy for them to grab. Very pleased and at a good price.

Will buy again
Color: Orange, Color: Orange
This was one of the first toys I got my dog and he LOVED IT. I sadly had to throw it away because he peed on it but this is something I will definitely repurchase. Perfect for tug of war and playing fetch. Definitely not indestructible as he did rip it a little but it took him a LONG time to do that

Perfect size for pittie pups
Color: GREEN, Size: 14 inch (Pack of 1), Style: FROG
This was a pretty good toy. I have three pitbulls. The puppy in my video is 65lbs for reference to the toy. I thought that since it was fluffless she wouldn't try to eat the thing but after a couple of days of tugging it with her brothers the toy's paw came off and I was not fast enough to prevent her from swallowing it. She got rid of it with little GI stress. I will say that even though she's not squeaking it in the video, it has a pretty loud squeak. Overall we had it for four days before 260lbs of pooches were able to get the squeaker out. If you have pits then you know this is 5-star worthy sturdiness.

An Instant Hit and Everyone's New Favorite
Color: GREEN, Size: 14 inch (Pack of 1), Style: FROG
An instant favorite! It took quite a while for my dog to break the squeaker, too. I love that it uses a water bottle for the crinkle sound, and I'm kind of glad the squeaker finally bit the dust. That works out well for us. It's tough enough that it's not ripped yet. Our dog plays with this toy every day.
No fluff to pull out was definitely a plus for me. It's a great toy for the price, and I think small and larger dogs would also enjoy it. Johan is 7 months old, weighs about 40 pounds, and always chooses a favorite toy. This one replaced a worn out toy frog that was smaller, but still treasured. I was so glad that he loves this one just as much.
It's a little bit longer than a regular-sized water bottle and has dangly legs. I think you could also put plastic that crinkles inside it, and they would love that too. It has a velcro closure to keep whatever you put in there inside, and he hasn't figured out how to open it so far.
Update: We just bought a second one of these because he enjoyed the first one to its conclusion. It lasted longer than most toys (about 4 months with HARD use by a giant puppy), and it is his most favorite soft toy. The original didn't rip or tear, but the velcro got worn out when he figured out how to open it. I probably could have fixed it easily, but since Johan is the goodest boy, I got him a new one.
