Quality material.
Size: Large
Puppy/Dogs like. Not chewed up yet, and looks to be very sturdy. I like purchasing my puppy/dogs rope like toys. And this one is good.

Francie Isn't Interested
Size: Large
Cute, colorful and appears well made. I can't comment on how well it holds up to heavy chewing as my Jackshund (Francie) doesn't seem interested in it...possibly because it does not have a squeaker... It is a good size, not soft and squishy but harder (rope), which is why I purchased it, hoping it would last longer than some other dog toys that Francie has ripped apart. I may pass it on to two large granddogs.
