Fun toy for a puppy or younger dog.
Color: orange & blue
These are fantastic little balls. They work very well.. I bought them for my 14-year-old dog and that was not a very good choice. However, they are wonderful and if you have a younger dog or a puppy, this would be a great toy for them.

Great toy for a very active chewer
Color: Green, Pattern Name: Hammerhead Shark, Color: Green, Pattern Name: Hammerhead Shark
My Pomsky who is 9 months has destroyed every toy we’ve gotten him so far and he LOVES this one. He took to it right from the box and hasn’t let it leave his side since. It’s a very durable, hard, chew resistant material and I have a feeling it’s going to last him a long time. Highly recommend! His smile says it all 😊

Durability
Color: Green, Pattern Name: Hammerhead Shark
I have a lab puppy and she LOVES to chew and tear anything that she can up. I bought this being a little bit hesitant by some of the reviews but I will say she has not torn out the squeaker yet,. And it’s pretty loud too (it’s been almost two weeks) and the plastic is pretty durable. The only negative I have to say is the plastic does it sharp ( I’ve almost cut myself on it) but that doesn’t seem to affect her. So overall I’d say this is a great product if your dog needs something durable yet chewable.

A Huge Hit in My Bully Breed House!
Color: Green, Pattern Name: Hammerhead Shark
I have a house full of bully breeds, and this hammerhead shark toy is by far one of their favorites.
I’ve actually bought a few of them so there are extras around the house — otherwise they’d all be fighting over the same one! That alone tells you how much they love it. The shape makes it easy for them to grab, chew, and toss around, and the squeaker keeps them interested without being obnoxiously loud.
What really impressed me is the durability. My dogs are serious chewers, and we’ve had these for a while now. They’re still going strong, which is saying a lot in this house. The combination of rubber and nylon seems to hold up really well to heavy chewing.
The bacon scent definitely helps keep their attention, and I like that I can add a little peanut butter for extra enrichment. It keeps them busy and off my furniture — always a win.
If you have strong chewers, especially bully breeds, this one is absolutely worth picking up. Durable, fun, and clearly dog-approved in this house.

Great for puppies
Color: Green, Pattern Name: Hammerhead Shark
Great for a teething puppy but very loud when it hits the floor. It is truly indestructible!
