Was so hopeful!
Style: Lobster, Size: One Size, Style: Lobster, Size: One Size
My dog Dax is like a big German Shepherd trapped in a little Chawinnie. he’s only one and loves to chew on stuffed toys like this. I was excited to try this brand out because it looked very promising. Unfortunately only lasted a little over 48 hours and he was able to gutt it out & rip off the eyes. He really loved it though, it has a different sounding squeaker and when he bit it the tail would flop up/down, I also like that the squeaker part was right in the middle which made it hard for him to get to it since his mouth is small.. despite that he was still able too. The size was perfect for him though so I’ll probably sew it up and give ir back to him then order another one. Giving 4 stars because it’s well made can’t help that my dogs ferocious!

My fur baby loves this toy.
Style: Lobster, Size: One Size
This toy works for my fur baby because she is a small Shih Tzu and not a rough chewer. It has lasted and has proved durable for her but may not be appropriate for an aggressive chewer or for a large fur baby. Because it is made of soft cloth I would not recommend for teething. Otherwise, I found this toy to be reasonably priced and one my fur baby loves to play with.

GoDog is usually tough; not this one
Godog is usually my go-to for soft toys that will last. My staffy/bully is a toy surgeon who like most pitties can shred a “ indestructible” toy in seconds. I have found a few that last him a long time: West Paw rumpus, some Fluff n Tuffs, some GoDog and the Benebone maple stick (although be careful with the latter, my boy broke a tooth on one 🤦‍♀️). He does eventually destroy some of those but more like six months to a year not minutes. He has a collection of GoDog dragons / dinosaurs that have lasted him like a year! They get ragged and sometimes one day he decides to really take it apart, but mostly they’re so big and have so many floppy parts that he just runs around proudly with them or sleeps with them or choose them gently for hours. This one wasn’t like any of the other godog toys we have. Maybe there’s a reason it was half off…Not tough at all. A toy has to last at least five minutes. It didn’t even last five minutes and the ears were off and the squeaker was out. Not well made. I do generally like the brand though.
