Doggos are excited but...
Size: Large, Color: 9 Packs
My dogs are ecstatic about their new ropes. But they're big and aggressive chewers. These ropes are thinner than the pictures made them look. I'd say they're appropriately sized for dogs up to 35 lbs - and not as great for the large breeds show in the pictures.

My dogs loved this toy!
Color: Orange & Blue
My dogs absolutely loved these! The quality is actually good and the price for two of them is fair! Surprisingly the durability is more than I expected my aggressive chewer hasn’t completely destroyed it!

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.

Great dog toys
Color: Orange & Blue
These Zeaxuie octopus dog toys are a huge hit with my pup! The crinkle and squeaky features immediately grabbed his attention, and he’s been happily chewing and playing with them ever since. I love that they’re stuffing-free, so I don’t have to worry about any mess. They’re the perfect size for small to medium breeds and seem very durable. These toys have kept my dog entertained for hours – definitely a great purchase!

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.
