My friend just lost her beautiful 5 mos. silkie on Thursday. She had her in the house and she heard thrashing and banging around and went to see what was going on. She found her laying spread out with her head twisted under her body. I think maybe she had a stroke or flew into something and broke her neck. I don't want to ask questions now because she is very upset - Peaches was her favorite and looked to be in top health.
