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

My dog loves this
Color: GREEN, Size: 14 inch (Pack of 1), Style: FROG
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.

Don't waste your money!

Do NOT buy unless you like throwing away your money! This Ethical Pets 54093 Skinneeez Frog seemed like a great dog toy, but my Malti Poo destroyed it within TEN minutes! He actually ate the material and half of the squeaker before I found the other half. Guess we’ll be seeing that outside in a few days! This toy is listed as “Durable Dog Toy”, but it is NOT. I’ve got dog toys from the dollar store that lasted for months! We will not be buying nor recommending this product again. Don’t waste your money!
