Cute but not for a super chewer
Color: Green, Color: Green
It’s a super cute toy. My boy loves the squeaker toys and he’s a fast chewer. Unfortunately for him, he tore it up within 24 hours. It’s definitely not for super chewers but he had a good time with it while it lasted!

Decent toy
Color: Green
My dog loves this toy. He's already tore through the head but the middle part he has not been able to tare through. It's a great toy for a chewer.

Fun Toy That Keeps Dogs Entertained
Color: Green
WOWBALA Interactive Squeaky Dog Chew Toy was purchased for my two granddogs, and they both took to it right away. The squeaker and soft plush design keep them interested and engaged during playtime. It’s great for tug-of-war and seems to hold up well with regular use. I like that it works for different sizes so that both dogs can enjoy it together. I will be purchasing another one for my dog at home. Overall, it’s a fun and playful toy that keeps them busy and happy.

Durability and lasting period of toy.
Color: Green
I got this toy for our bulldog. He had a hole in it, which will only progress, within minutes. I took it away until I could find out if there is any kind of warranty. The information says this toy is not for aggressive chewers, yet right in the description and the photo of the toy (that way I knew I was looking at the correct toy), it says for the "aggressive chewer". I am disappointed that even though it isn't how they described, it only lasted minutes before there was damage. Not sure if I would buy another product.

Won't last long
Color: Green
It lasted a couple weeks before my dog got it apart at the seams and had the stuffing all over the house. Won't hold up for long under aggressive play. I was going to return it, but my dog so loved this that I stuffed a sock in it and sewed it back together with heavier thread and more stitches. Hold up better for toys of the same price. Buy one, and have a sewing kit handy.
