Use only on dogs. DO NOT USE ON CATS or other animals. Do not apply to dogs weighing less than 4 lbs. Remove applicator tube from the package. Use scissors and peel down foil. Hold applicator tube in an upright position. Pull cap off tube. Turn cap around and place other end of cap back on tube. Twist cap to break seal, then remove cap from tube. The dog should be standing for easy application. Evenly apply entire contents of the tube along the top of the dog's back, from the shoulder down to the base of the tail.

Great for power chewers
Size: Large, Color: Bundle
Nothing beats Nylabone!!! Our lab has destroyed everything else… even the extra durable black kongs. Finally a chew toy that is super durable and great size.

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.
