My Boston loves this fish toy
Color: Cyan NylonFish
Very durable. It takes a couple of months of intense chewing to make holes in this toy. My Boston has incredible mouth strength so he destroys most toys in minutes unless they are rocks. I have replaced this fish 2 times in the last year. I keep an eye on the wear and replace it when he makes a hole in it. Worthwhile purchase but monitor the dogs chewing.

Great sturdy toy
Color: Cyan NylonFish
Great toy.
1 yr old puppy LOVES it! However, not good for TILE FLOORS. It's so strong and sturdy but bangs all over the tile! Enough to crack tiles 😬

American Bully Trial - Honest Review
Color: Cyan NylonFish
I have never gotten a toy that lasted more than an hour when it comes to my baby girl. She is an aggressive chewer and loves anything that squeaks. This definitely helped to keep her entertained and use her teeth. I can confidently say that this toy may last a long time but she has already ripped a piece from it. I didn’t expect anything less since she always knows how to test new toys lol. I would definitely recommend though and will be getting more for her once this one is gone. Thank you!

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…
