Not the most durable, but my dog LOVES it.
Style: Plush Surprise Color, Size: 24"
My boyfriend’s dog had the small version from Petsmart and she has been very gentle with it since she likes it so much. I decided to surprise her with this 24 inch one for Christmas. She was obsessed! It’s cute, it’s very soft, and has a big squeaker in the top, which she loves! She was a little more tough on it and it did get some rips 12 hours in, but it is still in one piece at the moment and brings lots of joy. The dog is a medium/large size. Dog toys can be so expensive. I personally think the was a great price despite not being the most durable. I may purchase again next year!

Puppy and price approved!
Style: Latex Surpise Color, Size: 6"
Great cheap little dog toys! Our 11 month large breed 90lb puppy loves to toss these around and squeak them between his teeth.. they eventually break down but that’s okay, at the low price of a couple to a few dollars each they make it affordable. They put some stuffing inside so it makes it slippery when our pup is nibbling on it. Funny enough these last longer than much more expensive toys that claim more durability! In 8 months we’ve gone through 2. That’s pretty good! Not chew resistant, but the latex offers a texture and squeak that I find makes our puppy go easier on them. Cute and easily packable.

Dog loves but not durable.
Style: Plush Surprise Color, Size: 24"
Our Golden has gone through 3 of these. He absolutely loves them. Contains two kinds of squeakers and crunchy noise maker. But they don’t last long so it’s good they’re inexpensive. Just wish the fabric was more durable.
