Hard, heavy, sharp
Color: Cyan NylonFish
This is very durable, but it is also very heavy (our dog likes to throw her toys) and after some chewing, the head and tail are very sharp

2 years later and it’s still going!
Color: Cyan NylonFish, Color: Cyan NylonFish
I have 2 dogs, a 6lb chihuahua (Lolli) and an almost 100lb German shepherd/Belgian Malinois (Uzi). Got this for Uzi, however, Lolli had other plans for it. She literally took it out her mouth and ran to hide it. It’s been over a year, closer to 2 and it’s still hanging on.
Attached a photo of Lolli…

Best found
Color: Cyan NylonFish
I have a heavy heavy chewer, the only things that has escaped him were items like "kong" solid and rubber but no squeaky. He quickly lost interest in the toy; largely within a week at most and never picks it up again unless really bored.
Squeaky toys had a life shelf of a week at best, that is with us taking them away to "preserve" them for longer. So far, this toy, the fish, has been the longest surviving squeaky and the longest at keeping his interest. it has received some cosmetic damage, but nothing that would make you remove the toy from his possession and it STILL squeaks.

Still holding up to my super-chewer!
Color: Cyan NylonFish, Color: Cyan NylonFish
It's a very good product. I would recommend this toy for a heavy chewing dog. My main reasons it's not 5 stars, it's HEAVY and the eyes peeled right off. My pup really likes to throw his toys around, this thing sounds like a cannon ball that's going to go through our floor! He also tries to destroy everything so he was chewing on the eyes and he would have definitely eaten them if I wasn't paying attention. It's not a horrible thing but I obviously don't want him to eat non food things. My dog also likes the squeaker in it, but it's difficult for me to get it to squeak. That's not a big deal though just thought I should mention it. Overall especially for the price, it's a good sturdy product that's cute and it's still holding up. He's chewed parts of the softer areas off a bit, but the rest is very hard so he hasn't made much of a dent. It's also about as big as his head, so he's pretty happy with it!

Worth it if your dog destroys plush toys & likes to chew
Color: Cyan NylonFish
My dog is a very big chewer and destroyer of toys. This toy is perfect for her. It is durable and keeps her engaged chewing for a while. I have a 55lb dog, considered a large dog, and it’s a great size for her. She’s unable to break it apart. The ends do tend to get a little sharp after extended use
