Wrong sorry.
The dog should be put down for showing enough aggression to actually kill another one of your dogs, You can`t pretend to justify this by saying the dog was jelous of your attention.
Yes it`s your fault, but not because you showed too much attention to the saluki, but the fact you allowed an aggressive dog to be kept as a pet in a situation that allowed iit to kill the Saluki.
Please don`t think I`m digging at you here, I`m not, I`m just stating it as I see it. I feel sorry for you having this happen, but you now seem to be saying that you want to keep the Rottweiler, o
