Holy Smokes, I Need Sound-Blocking Headphones
Color: Squeaker Matz Gator, Size: 2X-Large (Pack of 1)
This summer I bought the smaller version of this alligator squeaky toy for my large malamute-mix named Rascal. He's a big BIG puppy with an enormous amount of energy. Squeaky toys drive him crazy and he can't get enough of them. The more squeakers the more hyper he becomes. I started looking for the perfect Christmas present for him and caught sight of this little guy. Couldn't pass him up. 32 squeakers! Rascal would faint with excitement.
This toy is a little longer than 4 feet long- which is about how long my dog is. It's by far the largest toy he's ever gotten. The head has a rattle in it. And the long body has 32 squeakers individually sewn into their own pocket- so even once he has chewed one of the noise-makers out, he still has many more to go. A few of the squeakers came defective, but I suppose that should be expected when so many noisy parts are involved. I don't think he noticed. The enormous amount of racket he made with the rest of them kept him busy enough.
The second I gave him this toy he bounced around like any kid would on Christmas. Excited as heck. He spent a few good hours flinging the toy up in the air, running around the house and yard with it, and just laying around trying to chew each of those noisy things out from the body. He hasn't managed to get any of the squeaker toys out yet- it's been three days of constant play. He spends a few good hours on it each day. The fabric is getting kind of slobber-soaked, but that's presumable with dog toys. His dark black hair also easily sticks to this fabric, so it's beginning to look a lot dirtier than it actually is. But I'm sure he'll destroy it before my inner neat-freak feels the need to clean it.
My biggest concern are the felt teeth and claws on the toy. They can easily be torn off and swallowed by the dog. If you want to eliminate that, prior to giving your dog the toy- just take a pair of scissors and cut them off. I just monitored my pup closely and took away the pieces once he removed them.
Aside from the felt pieces and the fact the toy attracts hair- I think this was by far one of the best investments I've made for my dog. It's huge, keeps him entertained, and makes plenty of noise! I'm debating buying sound-blocking headphones before I purchase another toy like this again. Very noisy! But he loves it to death, and that makes it all worthwhile. Highly recommend!

My dog’s favorite toy
Color: Squeaker Matz Gator, Size: 2X-Large (Pack of 1), Color: Squeaker Matz Gator, Size: 2X-Large (Pack of 1)
This is my dog’s favorite toy! She carries it around everywhere and loves the squeaker. It’s a great size and keeps her entertained for a while. Holds up pretty well too, especially for how much she plays with it.

"Gator" under supervision for husky pup is loads of fun for her.
Color: Squeaker Matz Gator, Size: X Large (Pack of 1), Color: Squeaker Matz Gator, Size: X Large (Pack of 1)
Fun loving hyper 7 month old female husky whose an aggressive chewer loves her "Gator". She loves the squeakers, does chew on any & all parts of her toy as she like many textures from soft/fuzzy to hard. 1st Gator we got her lasted a few months. She did chew threw a good amount, it did get dirty & most of the 16 squeakers were missing but I saved like 5 of them & sowed them back in. Once she started chewing thru the head & into the stuffing we ordered a replacement & she's so happy. I have 1 picture of the Gator though it might not look like it's done it was. Zero squeakers remaining, head has 1/2 stuffing removed, torn stitches but not enough where the body could come apart. She managed to eat the stuffing but she was not hurtful & we were able to stop her each time. I recommend "Gator" w/ supervision if you have an aggressive chewing pup. It's durable enough for some tugging & "fetch". It advertised "encourages digging" @ the squeaker but she didn't. She tugged, chomped' "fetch" & whipped the toy w her head but had a blast every time. She actively searches for Gator when she wants to play w/ her toys. 16 squeakers.

Toy disintegrates - a hazard for dogs
Color: Squeaker Matz Gator, Size: 2X-Large (Pack of 1), Color: Squeaker Matz Gator, Size: 2X-Large (Pack of 1)
I buy these types of toys for my dogs. They rip them apart and pop the squeakers, having a great time. This is the third time over the past 2 or 3 years I've bought this particular toy. The quality has fallen off a cliff. Whenever my dogs shake it, flecks of the material fly off. These small pieces are very difficult to vacuum and, more seriously, get caught in my dog's teeth and throat. This never happened before, and they actually still have an old version that I occasionally resew with replacement squeakers. If you've bought this toy in the past couple of years, know that this is not the same product.
