Dogs love this toy!
Color: Drool Mint, Color: Drool Mint
My digs go crazy over this toy. They are both small and it’s the perfect size for them. It take a beating and still in great shape after 4 months!

The Zen Dog Toy
Color: Drool Mint
These were a cute dog toy for my son's dog. If the person who uses Zen has a dog this is a funny dog toy to get them

Our dog’s new favorite toy!
Color: Citrus Lick, Color: Citrus Lick
Excellent quality and happy to support a family business. Great crinkle and a good squeaker, she was instantly hooked. More durable than anticipated as well!

Perfect dog toy
Color: Drool Mint
My dog LOVES this toy. It has a great squeaker and it’s easy to throw. He also hasn’t been able to tear it apart. It makes us laugh too because he matches his dad. Great toy!

So cute! Not durable for tough chewers
Color: Smooth Pup, Color: Smooth Pup
Love this toy so much just because of how cute and funny it is! Our basset hound is a chewer though so he ripped through it pretty fast. Would not recommend for tough chewers. We even got a second and he tore through it just as fast
