It is good for tug a war
Style: Snake
The squeakers did not last very long with my poodle puppy. That was a disappointment. He does like to play tug a war with it. So I gave it three stars.

Durable construction, including squeakers!
Style: Snake
This is the absolute best toy I've found. My dog is a 40 lb staffie who loves to play tug and chew. I'm used to toys lasting one day to one week and this one lasted about four months of almost constant daily play. The squeakers finally collapsed, so I'm buying my second one. I wish they would embroider the name of their brand on the toy because I forgot what the brand name was and it was hard to find again. Thankfully, I combed through my purchase records and finally found it. This brand definitely is my go-to for durable toys from now on!

Very nice, LOUD toy
Style: Crocodile
My parents' dog had the shark version of this toy already, and I looked to see if there were any other versions of the same toy. I found this crocodile. This thing is hysterical when he plays with it. I think each squeaker makes a slightly different sound, so you can hear him switch from 1 part to another. This is not for you if you like quiet. It is very loud but our dog doesn't like toys that don't squeak. The shark has held up for along time, and the crocodile is doing well so far. He's pretty rough on his toys, but he hasn't torn these or broken the squeakers. The fabric is soft, and it's well sewn. There's no stuffing in the body or limbs, so small holes don't really matter. It's big enough for larger dogs (ours is 45lb). The price was very good for a large toy that's high quality.
