I am so very very sorry. I truly hate dogs these days. The puncture wounds looked bad when they first happened. She probably had internal injuries that you could not know about. Am I correct in remembering the offending dog was a husky? You need to do a couple things now. First when you are able this evening or tomorrow you NEED to go inform the owner of Aliss's passing. If there is a ounce of responsibility within the owner they will at least offer to compensate you for a adult laying hen, and that is not cheap, $40 to $50 would be fair. It is time to also warn the owner if you have not already. The dog has done this once, it WILL do it again. If it were me, the 2nd it stepped foot back on your property it would be a dead dog walking I'm sorry. I would have your dad with you when you visit the dog owner to inform them of this as well.
I loved my dogs, but I would never allow them access to my horses, foals, chickens and kids, unattended. One never knows what goes through their minds.
Now a-days I am so paranoid about dogs with the chickens, it’s bad enough with the horses, but my wee chooks make me very nervous with the thought of dogs about.
