Better than I expected!
Style: Variety Pack - Large (3-pack)
I have two pitbulls who can destroy any toy! My youngest one likes to chew on my fluffy slippers. She doesn't hurt them, just chews on the fur. I give her a lot of heck for this but she has an affinity for them. I decided to buy her a stuffed dog toy and she loved it! She proudly carried it with her everywhere and would throw it up in the air and catch it. She was as happy as she could be. The problem was that after a few days, my 5-year-old pittie wanted to get in on the action and they turned it into a tug of war. Five minutes later it was in pieces on the floor. I decided to see if there was such a thing as a cloth toy for aggressive chewers. I found these! They weren't that expensive, so I thought, "what the heck", I'll give them a try! They arrived the next day! I took two out of the pack and within two or three days they had killed the squeakers in both of them, and I was thankful! The squeaking was loud and they could not get enough of it. There were three squeakers in each toy! After the squeakers were gone, they seemed to lose interest. So I started doing tug of war with them. Pretty soon they were doing it with each other. I didn't expect them to last a day! However, it has been almost a month and they are still pretty much intact. I mean these dogs are for real and they pull as hard as they can and they still have not ripped them apart. And it's great exercise! There are a few small holes in them but they are not getting bigger. I guess that is how they got the squeakers out! Even the eyes on these toys are still there. I put the third one away for when these two are demolished, but I think I will order another pack of three. That will give me four all together! That should keep them busy for quite a while!
I just want everyone to know that I am pretty limited with my reviews. I don't bother unless I really have something to say, so you can totally believe what I am saying! I don't think you will be upset with this purchase, unless you don't like saliva soaked toys and/or your dog is prone to swallowing it's toys. It is very hard for me to imagine a dog swallowing one of these. From the top of their heads to the tip of their tails they are over a foot long!

Good quality. Decent price.
Style: Fox, Raccoon, Squirrel
The small size is perfect for my 13# dog, but I was somehow under the impression that one squeaker was in the head while the other was in the tail (and that might be the case for rhe larger size), but one us in the main body, with the other in the tail. The head is flat, and there's no way to push the sqeaker in the body up into the head.
Ordinarily, this wouldn't matter -- and my dog LOVES the one I gave him so far; he's squeaking up a storm! -- but I bought these toys specifically so I could fill the (presumably empty, but in reality not) body between head and tail with chopped up pool noodles so my paraplegic dog could take it into the water treadmill treatment he's starting in a couple weeks. I wanted something that would float and be largely waterproof (no fluff inside in case he drops it in the water), that he could hold in his mouth instead of wearing a muzzle.
I've rated these toys 4 stars because he does love them, they seem well made, and they're pretty affordable. I would buy them again, though not for the same purpose. (He hates rubber toys, so this was my last hope. Lol?)

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.
