Not durable

Lasted all of 30 seconds (with a 2 year old golden retriever). Very disappointed in durability.

Puppy loved it too much
Size: One Size, Color: Purdue Boilermakers
Our puppy showed her team spirit by focusing a lot of attention on this toy. She loved chewing on the ropes, chewing on the seams, fetching it, and playing tug-of-war. It’s easy to throw. But after about three weeks, she tore a hole in it and spread the fluffy white filling everywhere. We might even buy another one and just take it out of rotation every few days to make it last longer.

Cute but not durable.
Size: One Size, Color: Kansas Jayhawks
Our doodle loved it…for about 30 minutes before it was destroyed. The material making up the ball is somewhat thin and he tore through it easily. The knots on the rope he quickly pulled open and the rope frayed. It’s cute but not really for a puppy to play with.
