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.

Very Sturdy and Safe for Tough Chewers
Style: Muskie
We already had a smaller fish toy from this brand, and after 4 months it is, amazingly, still intact. So we ordered this larger one as a holiday present. Our dog usually can rip apart any toy, even "tough chewer" toys, within a few minutes or hours, so this brand is a definite keeper for us. We have also had their giraffe toy for 4 months with no rips or holes. The best part is that there is no stuffing to worry about. Inside the toy is a rope toy instead of stuffing, so it is so much less risky. Highly recommended.
