Longest lasting dog toys we’ve purchased.
Style: Fox, Raccoon, Squirrel
In 2020, we purchased these for our 6 month old puppy who was repeatedly destroying all of her toys. Christmas 2025, I gifted our dog a stuffed toy purchased from a local dog store. It was destroyed within an hour. Later that day, I found one of these little squirrels that we purchased FIVE years ago - still in action, a bit worse for the wear, but still very much loved by our dog. I decided to purchase another pack of these as they are clearly winners.

The Ad got me, the reality didn't
Style: Variety Pack - Large (3-pack)
Directly from the ad- "Exclusive Noisemakers - Each large toy includes 3 high-quality round squeakers to deliver more sound to keep your best friend entertained.". Now my neighbor bought this squirrel with three high-quality squeakers nearly a year ago. It's ragged and tattered I just recently sewed it up for him where he chewed the one leg odd, but those three noise makers are still squeaking. Whe I got my pup, I immediately went to buy one and they were no longer selling them, so I've been on a search for one or an equivalent. These are not. There's no stuffing to get all over the place when your pup breaks into it, a plus. However the squeakers weren't particularly loud and were silenced in a few hours. Two were dead and the remaining one was very well on its way. The toy itself was pretty much intact but that had more to do with the lack of attention from the dog than how rugged the toy is. He'll pick it up once in a while but it certainly didn't meet my expectations. The good thing is that there are three of them so I can give him some brief excitement in the future. Wouldn't buy again.

Strong Chewer Friendly Toy
Style: Variety Pack - Large (3-pack)
My dog is a rough chewer and these last a really long time (clearly since this beaver's face is long gone! The no stuffing is a win too for cleaning up afterwards.

Fantastic Dog Toy!!!
Color: Purple
This is a great toy!!! My dog has lots of toys. But one of the problems is he has trouble getting the squeaker to squeak. He's an 18 lb terrier mix, and those squeakers are just elusive. Breaks my heart. This one, though, the squeakers (there are two) are in small areas (head and tail), that are easy for him to get his whole mouth around and squeak. They also don't move, which also makes them easy to squeak. So he's been squeaking up a storm since he got this! Other plusses: * The material is great (soft, furry material, that seems to be of good quality). * The toy expands and contracts, which is fun. * It's pleasant to look at. All in all, I'd say this is one of the best dog toys I've ever bought for my dog. Highly recommended!
