Tough toys!
Color: Orange & Blue
We have 2 deogs, a large Aussie and a small terrior. The little guy is very hard on toys. Few last a full day. We have thrown away hundreds of $ worth of toys, We have had these for a few months, and he has not managed to destoy them yet. They get played with a lot because he has very few toys. I keep trying to find toys which will survive this dog. He hjas even destroyed Kong toys which are pretty tough, but has not destroyed these. I wrote this review as I cam back to order more toys from this company, because it is great to have some which can stand up to his abuse.

Our dogs love these
Color: Orange & Blue
We have two rough collies that love to play fetch, tug, and ragdoll. We decided to add these to their play toys. Since getting them they have been ignoring their ducks and going straight for the octopus. We just got them so can’t say much about durability yet but they have been playing with them for hours and still look brand new. Love giving our dogs choices so we can ask them for certain animals to fetch. Love the non-stuffing and the crinkle.

Not for Aggressive Chewers
Color: Orange & Blue
My Dog Loves them. He immediately took the squeaker out, and dismantled some of the legs, but he still runs around trying to play tug-of-war and fetch with the dismembered body piece's 😂☺️
