I purchased this for our trip to Texas from Alabama with our 2 year old American bulldog in tow. I wanted something that was able to keep her secure, but something that would be comfortable for her. I was also concerned about sizing because even though she is a medium sized dog, she has a wide chest. I got an XL. It fit her perfectly with the adjustable straps, it was easy to get it on and off of her, she didn’t mind it at all, and the straps were strong enough to keep her safe and in place.

Chew toy that will last!
Color: Blue&Red Fish
Great toy for a real chewer. It's been in the house for about 5 days and the toy is still intact and the squeaker is still squeaking.

But a big baby, especially when it comes to his toy\nOf course he's tough on them But These definitely held up well. So if you have a.n aggressive Chewer these are an excellent choice
