poor quality product
Color: Carrot Orange
very poor quality. The actual color is not as picture. more like being washed many times. the rope knots went loos almost immediately after a few play. The worst part is the so called "squeaky" whistle, you have to squees very hard to hear a little sound. don't buy it!

Dog loves even though they are thin product dog loves them and Picks Them out of many many toys.
These were super thin and I thought about tearing a hole in them and putting in a slight bit of stuffing. However, my dog absolutely loves them and we fling them across the house and the yard like little Frisbees. They are very lightweight but kind of a corduroy stitched fabric and they have lasted quite some time and been through the washer and dryer many times and abused. Still holding up and the dog loves them. Highly recommend a great product for the price.

Will Buy Again--Eventually as they are hearty
My dog loves these "trash babies" as the size, squeaker & trash /cellphane sound the crinkle toy makes brings her joy. this brings me joy as the stitching is hearty and toys hold up when cleaned in my washing machine & dryer. Her first trash baby is still going strong after a year tho the crinkle sound has dimminshed some the sweaker is good as new. I bought these to rotate to wash and keep a new one for travel. Very durable! good size for my 20 pound mini aussie.

Cute, big enough and top notch quality
These are SO CUTE! The look exactly like the pictures so I am really glad about that. They are quite substantial in size, big enough. See pics :). I gift one of three to my friend's dog. The texture is soft and boucle like and soothing for me and the doggos! The squeakiness is very prominent but not present in all parts of the toy - so its annoying. I am also glad these have no stuffing because they look great as is and lack of the stuff make them easy to chew on. The cuteness got me on this one and I may repurchase again, if need be.
