Cutesyyyy
Size: Small (9 in), Style: 2 Knot Rope Bone
My dog loves this rope toy! I thought it would feel cheap and unravel easy, but it actually seems quite durable and my puppy seems to like the way it feels as well.

Close...but not quite the length.
Size: XL (16 in), Style: 2 Knot Rope Bone, Size: XL (16 in), Style: 2 Knot Rope Bone
I will admit, I thought their picture was off, because when I saw 16" in the title I was expecting the distance between the knots to be 16 inches in length. So if you're looking for a good length tug-of-war rope for a medium to large dog, look somewhere else. I'm not returning it, it's good quality cotton rope asides that. My dog needs a new toy and cotton ones are harder to find. Next time I'm going to their amazon store directly to look for what I wanted though. I will buy from them again, I like the quality and the fact that, for once, cotton is actually cotton.

Great toy
Size: Small (9 in), Style: 2 Knot Rope Bone
I got this because my puppy chews through the other kinds of rope toys. This one is laying though. Only thing is, she's eating off the loose strings. Lol So she's pooping strings all the time

The strings on the end are super engaging and the rope itself holds up really well
Size: Small (9 in), Style: 2 Knot Rope Bone
Super cost effective way to redirect chewing!! Our 4 month old corgi quickly made this is favorite toy. He loves the strings on the side and tugs on it endlessly, and the main rope was pretty firm at first but has softened up while maintaining its strength. Highly recommend as an interactive toy or just something for your dog to chew on their own so you can take some time to chill on your own!

Not for aggressive chewers!
Size: Large (14 in), Style: 2 Knot Rope Bone
At first glance, this rope toy seemed sturdy and well made. However, within an hour of my Vizsla chewing on it, she had already bitten off and unfortunately swallowed several of the fringes. The center of the rope also began to unravel. This toy may be suitable for smaller dogs or those that aren’t aggressive chewers, but I wouldn’t recommend it for large dogs or heavy chewers. Additionally, while it may measure 14 inches before being knotted at the ends, the total length is shorter than advertised.
