Very good
Color: Blue
Tried this ball with a friend’s dog. It moves in fun ways and holds the pet’s focus for ages. Tough material resists bites really well.

Not for big, brave dogs.
Color: Blue
So maybe if you have a little dog, or a timid dog, this could be good. However, my 7 month golden just grabs it and carries it with her head shaking and then wants to chew it. So while it’s kinda funny, and she does love it, I just have to walk around trying to keep her from chewing it up. It is as advertised and seems pretty sturdy. It is soft enough to gently throw but is very easily retrieved and then the shaking and chasing continues. Not what I expected.

Great Value Toy
Color: Crinkle Duck (Blue), Size: Large, Color: Crinkle Duck (Blue), Size: Large
This toy has been one of my dog’s absolute favorites. He gets excited every time he sees it and will carry it around the house, toss it in the air, and keep himself entertained for a long time. The shape and texture seem perfect for him, and it quickly became one of his go-to toys over everything else in his basket. What I really like is that it holds up reasonably well for the price. It’s definitely not indestructible, and after a lot of play, it will sometimes start to rip—usually around the feet first since that’s where my dog tends to grab and chew the most. But honestly, considering how affordable it is, I don’t mind replacing it when needed. It’s inexpensive enough that rebuying feels worth it because he genuinely loves it that much. I’d rather keep buying a toy he is obsessed with than spend more on something that just sits untouched. It’s fun, cute, and keeps him happy, which is what matters most. Overall, I’d definitely recommend it for dogs who love plush toys and playful chewing.

Best affordable squeaker toy
Color: Crinkle Chicken (Brown), Size: Large, Color: Crinkle Chicken (Brown), Size: Large
my dog is obsessed with this toy, this has became his new comfort toy and after having this for about four months the legs are falling off but it’s very durable. The squeaker also moved from the head of the chicken to the body of the chicken but that’s after it was played with every single day. I love that it has two squeakers and it’s the perfect toy for my dog.

My dogs favorite toy EVER
Color: Crinkle Chicken (Brown), Size: Large
I have a Belgian Malinois who loves any and every toy, but this one is definitely her favorite. She will walk around the house constantly carrying it in her mouth, which is honestly adorable to watch. The squeakers only lasted a couple of months, but I don’t really consider that a downside—I’m kind of grateful they didn’t last forever given how much she plays with it. It still remains one of her most-loved toys even without them. My only word of caution is that if you work from home, this toy makes a lot of crinkling noise. And I mean A LOT. It’s great for keeping the dog entertained, but it can definitely get a little frustrating for humans trying to focus or take calls. Overall, it’s been a big hit in our house and easily one of her favorite toys.
