    Bigger, louder, crinklier, softer, than expected!
    Size: X-Large, Color: Rabbit
    My dog was gifted a collection of used toys and he really likes a very long stuffed pig which, unfortunately, another dog that is a destructive chewer, totally destroyed. I decided to break down and buy him another long stuffed toy today and since he's always blissfully watching rabbits in the yard and neighborhood I chose the rabbit version. This thing is huge which is great for him- he's 62 lbs and 7 months old and only half grown. He loves it, it has multiple LOUD squeakers, lots of crinkly spots, and fun ears/legs to grab hold off. He's a big fan and it's made with K9 Tuff Guard which LASTS. Super soft and easy to wash. Update after 2 months- easy to wash and looks new after a washing. very durable so far, standing up to indoor and outdoor use. He is not a destructive chewer but whips them around, tramples on them, steps on them while running top speed and chomps on the annoying squeaker for hours. one squeaker has a hole and its tune is now slightly muted (thank god)

    So many squeakers!
    Color: Squeaker Matz Gator, Size: X Large (Pack of 1)
    I have 3 golden retrievers. They love this toy. While the head came off because they played tug-o-war with it, the rest has held up mostly for 5-6 months. At this point sometimes a squeaker will pop out. There are so many squeakers in this toy! However, they still use it for tug-o-war, I am surprised it has lasted this long. There is only stuffing in the head.

    Cute, durable toy.
    Color: Squeaker Matz Gator, Size: X Large (Pack of 1)
    It's about as durable as you can expect a stuffed animal to be. I have two new puppies who are still teething and they love these things. I got the Kyjen sheep mat version (it's a square shape, rather than the two rows of squeakers) for the little girl. Both dogs sleep with it in their crate and we take them on trips with us. I've gone so far as to open up the toy and replace the broken squeakers (costs about 5$ for 30 large squeakers). The rest of the toy is fine. Our german shepherd puppy absolutely loves the rattle that's located in the head of the gator as well. The rattle also helps initially getting the dog engaged with chewing on the toy rather than your clothing or furniture. Then they discover the squeakers and it's endless entertainment and a good distraction for your dogs. I haven't had any problems with the thin, decorative material that's represent the teeth, claws and back fins. It's a slightly thicker felt that's soft and flimsy. Honestly, I'm not worried about it. Even if they were to eventually chew these off, they're not a choking hazard. Our little guy has thrown up solid pieces of kibble that are larger and harder than this. Seriously now, common. The eyes are sewn into the head, so there's no risk of pulling them off and swallowing. I toss these in the washer on a gentle cycle to clean off the slobber and dirt about once every couple weeks and the squeakers are fine, though they sometimes have to dry out to be 100% functional again. It never takes long. Overall, I love the amount of squeakers just due to the breaking problem with have with single squeaker toys. Once they break, the dog loses interest. Which is also a nice way to train the dogs the difference between the non-squeaking kids toys. The dogs absolutely love this toy and wont sleep without it. When the fabric eventually wears out (not even a slight issue after a few months), I'll be buying another one.

    Great Toy, HUGE, small dog loves,
    Color: Squeaker Matz Gator, Size: X Large (Pack of 1)
    For the price this is my favorite toy! My 4 lb Chihuahua LOVES this thing. He is smaller than it by a long shot, yet he loves to parade this around, showing how big he is and can handle this huge GATOR. LOL. Friends come up to the porch, and he runs back to grab his GATOR to bring it up for them to see. Only thing with these toys - for my dog - we have several of these he loves - he cannot make them squeak. He jumps on them, chews on them, but just doesn't have the power. That being said, think about it, he loves the things, I mean LOVES. Sleeps with them, parades them out, fights with them when he's alone, has a great time - .... Evidently, it's me - I MISS THE SQUEAK! I watch him, and root for him, and every now and then (rare), I hear he got a squeak. Still, he doesn't care! So.... interactive time! I go out and play with him and Mr. GATOR, and I make it squeak, and we all have EXTRA fun. Note, my little guy is what they call an EXTREMELY AGGRESSIVE CHEWER. He chews in his sleep (kidding). He's really a tough chewer. He however, uses these more for wrestling, and attacking, and carrying around and sleeping on, etc. So none of ours have tears in them, though he does attack and chew all of it - I think these products are super wonderful, and I have to buy several more, like the hide-a-toy ones (beehive, squirrel, etc.) because I know the quality, I know my Chihuahua loves them to pieces - while he hasn't actually been able to render them in pieces! Win-win for us. You decide what your dog is like. Mine has his snoopy blanket and a huge victory in his mind over this large GATOR - his friend all day long.

    Great Toy, But Not Durable
    Color: Squeaker Matz Gator, Size: X Large (Pack of 1)
    I bought this toy for my five-month-old American Eskimo dog, and he loved it! My dog isn't a big squeaker fan, but he had so much fun with this toy. He played with it nonstop for about an hour, and it was so fun to see him enjoying his toy. Unfortunately, I had to take it away from him because after a while, he was trying to rip out the ridges that line the alligator's back. He managed to rip out two already and was working on his third. I'm afraid that out of boredom, he will try to tear off the rest of the ridges and then the alligator's teeth and claws. I think that I will have to snip off all of the small pieces before giving this toy to my dog again. Even though the toy didn't stay intact for longer than 30-45 minutes, I don't regret buying it. It instantly caught my dog's attention and kept it. This is a good toy. It has 16 squeakers and would be a good cuddle toy since it's soft and big. This toy is longer than my dog! It's about 30 inches long!
