SOOO DURABLE!!!
Pattern Name: Tug Rag
VERY VERY VERY durable!!!!! I have a Malinois and a Cane Corso who are both very high energy and high intensity. They have shredded every single toy, bite rag, and rope ive purchased butu this one has stood strong for a year so far. i would 100% buy again. could also just be thrown in the washer if it gets dirty which is a HUGE plus for super droolers.

Ok but not Leather
Pattern Name: Tug Rag
I will say it's fairly durable but when the description uses the word leather..one would expect LEATHER, not microfiber. That said..it is thick and pretty durable and the dog does like it ok. Obviously the strap is NOT meant for chewing. This is not a throw it on the ground and let ur dog have it sort of a toy. It's an interactive toy. If left to the dog most would scissor the strap off in the first 10 minutes. Something to keep in mind. In summation..an ok interactive toy but over priced for the material.

Well-made and great size for the price!
Color: blue black
Very tough product, no odor of plastic, good toy for outside, perfect for medium or large dogs. Noise isn't too bad and the color is cute as well. Can't destroy this toy!

Durable Great for aggressive chewers
Color: Blue
Will make one whole room smell like fake bacon, but my dogs love it and it’s super strong and durable. I have a lab mixed with rotty and a full lab so it’s a perfect match.
