It is not a good product for a dog. I didn’t even last five minutes.

I received this package and I just gave it to my dog. Doesn’t last five minutes. It’s already tore up.

Totally worth the good price!
Size: 6 inch (Pack of 1), Style: Rabbit
My little shi-tzu has a favorite toy. It’s a stuffed lamb that she has, over time, completely torn to shreds. I needed something cheap on another order to get same day shipping, and I’m now tickled to pieces that I thought to find her something new to play with! When the box arrived, I called my little Mocha and built-up the opening of the box letting her know she had something in there. We never really get to buy her anything, so this was just too much fun 😂 As soon as I picked it up, I planned to toss it for her cause she loves to fetch things. Yeah, didn’t happen. She was so excited, she had this bunny out of my hands before they made it out of the box! Love that it’s made for dogs, and comes without things you might need to worry about, like eye buttons popping off, etc. The little tail did come off pretty quickly and since it was small, I tossed it. The bunny itself is played with at least once or twice daily, and she hasn’t broken through to the stuffing yet. So, for a cheap dog toy, it’s holding up really well. Happy with this purchase and would order something from them again.

Adorable, but probably not for medium+ dogs
Size: 6 inch (Pack of 1), Style: Rabbit
I got this for my 20 and 30 pound dogs to play with, and though I didn't really expect for it to be a durable or long-term toy for them, I think it felt like it was well-made and would probably suit dogs that are up to 15 pounds the best. It felt better than other dog toys in this price point but was filled with holes already after the first time my dog played with it on his own, which I think is probably more of a fabric issue than an actual quality issue, because it was more of a teeth puncture than seams ripping. I hope this helps! I would definitely recommend it to anyone with a small breed dog who doesn't have the same bite strength .

My dog loves these
Size: 9 inch (Pack of 1), Style: Bone
My dog usually doesn’t play with toys but I decided to try this one. She loved it so much that I ordered 3 more to have on hand! Some of the stitching on the first one is coming apart but it’s actually quite durable given how tough she is on it.

Tail came off right away
Size: 6 inch (Pack of 1), Style: Rabbit
Our little dog kept stealing a stuffed animal off our granddaughter's bed, so I decided to get one that was better suited to him. I liked that there weren't any eyes to pull off, although it does look weird without eyes. He really likes it and carries it around. The bad part is the tail came off almost immediately. He isn't one to chew up toys, so I just don't think it was attached firmly. I haven't tried to put it back on. I may just leave it off. So far the rest of the bunny is holding up.
