great dog toy for small and large!
Size: Medium (Pack of 1), Style: Gator
we have a very large silver lab that tears through toys, and very fast! some toys only last a day while others last a week or so... he has yet to tear this on up at all and we have had it for about 3 weeks. we also have a very small teacup yorkie, so some toys we get he cannot even play with, this one he can squeak and carry around which is great! it very quickly became one of their favorite toys! will buy again if he ever does destroy it !!! update: after a month of the lab and small yorkie playing with this some of the fabric stared to tear on the end of the toy, they still love it and it still squeaks perfectly fine. didn't think it would last this long with the big lab, will order new one when they do finally destroy it for good

A must have for my little puppers
Size: Small (Pack of 1), Style: Monkey
Bought this for a Chihuahua. He came from a bad situation that gave him screaming dreams of terror in the middle of the night, waking up, screaming. I would find him frozen in absolute terror. Poor dude. Now, he seems full of rage, and I get it because I know half of his story. And we love him anyway. He has 2 big brothers that will help show him the way, living his best life ever! Long story short; I first started buying this Petstages toy many years ago for my blind MinPin. Seeing it still, out here for sale always puts a smile on my face. Back then, they were a better quality. Now-a-days, the material around the squeaky is on the loose side, making it easier to destroy when my big dogs get it. Still, it brings back wonderful memories, is soft for a small dog that doesn’t destroy his things, it squeaks and they are usually loud (which is a must have, if you ask me), and it is cute to boot!

THE favorite toy
Size: 1 Count (Pack of 1), Style: Shark, Size: 1 Count (Pack of 1), Style: Shark
I found this toy used at a thrift store almost 1 year ago. My Shih tzu mix loved it so much till all the seams ripped out and 2 out of 3 squeekers fell out and it was shambles, hardly usable at all. 1 week ago I decided to try my luck to find a similar shark toy for Finnegan. I couldn't believe my eyes when I found THE EXACT same toy!! When I unboxed it, I put the old and new side-by-side and imagine his surprise, it was priceless! Very pleased with this.

Best Dog Toy Ever!
Size: Small (Pack of 1), Style: Monkey, Size: Small (Pack of 1), Style: Monkey
Unbelievable. See below previous reviews. Today is 3/22/2023 (4th Update): Cavachon is now three years old. THIS MONKEY is STILL played with DAILY. She’s played with and lost interest in dozens of other toys in the past three years, but Monkey is always the go-to. Now only on Monkey #6, which is remarkable considering the daily torture she puts Monkey through. Other toys get destroyed, but Monkey endures. This toy is our dog’s best friend and playmate! 10/9/21 (3rd update): Its rare that any toy (without food inside) keeps the interest of our Cavachon for even 30 minutes… yet day after day, she runs around with Monkey for at least an hour. She’s on her 4th Monkey… and this thing gets mauled, chewed, super-squeaked, fetched, and shook violently EVERY DAY. Durability times ten! 2/21/21 (2nd Update): Crazy pup is now 14 months old, and she plays DAILY with “monkey”! She’s on her third monkey because eventually she pulls off the tail, but each of her first two lasted months. ORIGINAL REVIEW MAY 2020: There is something really special about this monkey... Our 5-month-old Cavachon LOVES this toy. I recently ordered a second one, in case she wears out the first one. She knows it’s her “monkey” and finds it when we ask her “Where’s monkey?” She fetches it, walks around squeaking it, and she also zooms around the house shaking it furiously by the tail. She’s been playing with, and chewing on all parts of It, DAILY for three months. In the photo, you can compare the brand-new one, still on the cardboard, with the one she’s mauled for three months. Not much difference. I would say this is an extremely durable, and safe, toy.
