Binky?

Nope, Binky was flesh and blood, as explained in Reaper Man:

Death's pale horse looked up from its oats and gave a little whinny of greeting. The horse's name was Binky. He was a real horse. Death had tried fiery steeds and skeletal horses in the past, and found them impractical, especially the fiery ones, which tended to set light to their own bedding and stand in the middle of it looking embarrassed.
