Best Toy Ever! 🐾
Color: GREEN, Size: 14 inch (Pack of 1), Style: FROG
Hey, it’s me, your dog! 🐶 This Frog toy is AMAZING! No stuffing to pull out (finally), so I can chew and squeak it all I want without making a mess. The squeaker is SO satisfying, I carry it everywhere. It’s the perfect size for playing tug-of-war and fetch with my human. I’ve had it for a while now, and it’s still holding up strong—no rips or tears yet! If you love squeaky toys and want something that lasts, this frog is paws-itively the best! 🐸

Dog toy
Color: GREEN, Size: 14 inch (Pack of 1), Style: FROG
My dogs have destroyed this toy. Squeaker gone in a day and is ripped open. It was a great little toy just not for use with heavy chewers

Easy to insert bottles into and easy to toss. My dog loves that it both squeaks and crunches. One of his new favorite toys.

Not durable for a large breed
Color: GREEN, Size: 14 inch (Pack of 1), Style: FROG, Color: GREEN, Size: 14 inch (Pack of 1), Style: FROG
I received this toy about 2hrs ago. My dog tore a hole in it already. Not made for Rottweiler/American Bulldog breed, apparently. 🙂 Love that there isn't stuffing though, at least she's not making a mess, lol!

My dog loves it.
Color: GREEN, Size: 14 inch (Pack of 1), Style: FROG
I thought I was going to have to return this dog toy because my dog was afraid of the toy, especially the squeaker. But after a while, he finally did start playing with it and now he won’t let the other dogs touch his frog. It’s so bad that if they do touch it, he rips it out or their mouth, jumps up into a chair, and lays on top of it so they can’t get it. He still doesn’t like the squeaker if it’s down in front of him, but if I’m in another room, the squeaker makes him come running. He loves the squirrel I got him too. But the material of the frog seems really durable. The part I like the most of that it’s like a puppet and you can stick your hand in it or an empty bottle of water and then Velcro it shut. If your dog doesn’t like the squeaker, there is a pouch in the mouth of the frog that you can access through this velcroed area and cut it out. Definitely a must have if you have a tough chewer.
