Poor little Dennis. That's so sad, and he was only a baby.
How awful for you that it brought back such painful memories of Loki. It must have been heartbreaking enough without that added grief, and the reaction of the other horses.
It is amazing that both you and the owner both woke at 5am, and your stomach hurt. I remember reading the fascinating thread at halloween about spooky happenings, and what you said about your experiences, which are incredible. You must be very psychic, or very lucky. I find it so comforting to think our beloved animals let us know they are still around. I've had a few things happen since losing my gorgeous dog a year ago, and it has helped as I still miss him so much.
Sending hugs to you and Dennis' owner at this very sad time.
