Not chew proof but great for stimulating your dog!
Size: Large, Color: Octopus - Multi Color, Size: Large, Color: Octopus - Multi Color
8 legs gone in one night! Haha to be expected because my dog is a heavy chewer. Like other costumers we are left with a blue ball which she still plays with. It’s a great toy for days that my dog really needs to get energy out. She was so tired after, she was panting like she ran for miles. I suggest combining physical exercise with things like purposeful chewing or licking toys to tired them out. Doing this has reduced my dog’s anxiety tremendously over the years therefore reducing destruction of our furniture 😅 a tired pup is a happy pup!

It’s not for a big dog with large teeth
Size: Large, Color: Rabbit
The dogs Already chew its nose off
Didn’t last 2 days. We are trying to sew it up. It will probably end up in the trash
Thought this bunny is very cute. I’d only buy it for children to play with it. Or maybe a tiny dog.

Great despite mild defect!!!
Size: Large, Color: Octopus - Multi Color
this is a great toy for my pup! I love goDog toys because they last a long time for my destructive Aussie. This is my dog's favorite toy right now. He brings it to me constantly for a nice game of tug-o-war. It did rip within a month but the rips are staying intact thanks to the method goDog uses to put these toys together. I would not drop the rating for this, but I will admit the bottom cloth used to sew all the legs in tears easily. It is doing well after I sewed reinforcement into them but it would be nice if GoDog found a way to reinforce that piece to improve the toy.

Emotional support
Size: Large, Color: Octopus - Multi Color
Greatest toy ever! My dog is in love! This is like her emotional support toy. She sleeps with it and chews on it throughout the day. The only issue is the seams break open and the stuffing pops out after awhile. I just grab needle and thread and sew it back closed. Washes well too.
