The only toy my dog wants
Color: Gator, Size: Large, Color: Gator, Size: Large
I have a 9 year old, 12 pound chihuahua, and this toy is everything to him. Ever since he was a tiny puppy, he’s liked toys that are at least as big as he is. Once I got him this, it was the only toy he’d play with. He carries it everywhere. He likes to chew on it, and sometimes pulls apart the threads. He LOVES to play tug of war with it, so the handle is awesome. It has so many squeakers, which is also a plus, and it holds up well for our little guy. We’ve probably had at least 10 of this same toy, we get him a new one about once a year when it starts to get worn. I worry that if they ever stop making it, he’ll be depressed lol. It’s been with him at all life stages and he doesn’t go anywhere without it. Really can’t ask for more when your dog loves a toy this much

Lots of squeakers in this one!
Color: Gator, Size: Large
Our rescue dog is a power chewer so this one doesn't last long, but I still gave 5 stars because it's not advertised for power chewers, so I knew what we were getting when we bought it. So why did I buy this for our dog? The number of squeakers... the dog goes nuts for those and it makes the toy last longer because she will only play with the ones that still squeak.

NOT for aggressive chewers!
Color: Lion, Size: Medium
My aggressive chewer had destroyed this in 3 minutes! Chewed off the ears, and chewed apart the body to try to get to the squeaker - it was in the trash 5 minutes after I gave it to him! Yes, the seams are tough, but he easily chewed around them. Don’t buy this if your dog is an aggressive chewer!

Somewhat durable.
Color: Elephant, Size: Small
My dog loves these toys, I think it's the squeaker. I've tried several and this elephant one holds up the best.

Not tough enough
Color: Elephant, Size: Small
It might be tough, but my 26 pound dog managed to rip it open in record time! The only good thing, the squeaker is a long plastic one and easier to grab before she can swallow it!
