It was more difficult that I had anticipated. The fibers were much shorter than the wool I'm used to so I disliked spinning it for the same reason I dislike spinning cotton. Although I must admit that the finished product is much more satisfying since the dog's owner (and possibly also the dog itself) will enjoy the finished product. I wonder if the dogs will recognize themselves when they see/smell it.
I accidentally left the husky yarn ball where they cats could get it one night and they did quite a number on it. They do the same thing to other yarn when it's left out so I doubt this was a dog vs. cat-related act of violence. The yarns are unbelievably scratchy so perhaps it was "fighting back" with them.
The other fur samples were too short to spin, so I will do some experiments with making them into felt and see how that goes.
