I would think Lab hair would stack nicely. Looks like it spins fairly well, too.

We have inherited my daughter's Shitz Tsu, as well, but her hair is quite different and I am not sure how I would use it. Kinda long and flowy. If it was as long as it is supposed to be, I might try weaving it. It might make good zonkers, but I don't think my wife and daughter would approve of the process.
