To me culling can be as simple removing from the gene pool. Spay/neuter and find a pet home.
Dog or human aggression equal euthanasia for me.
agree its not killin the dog or dumping it out somewhere, but yet again its these "people" that do that and it makes a bad rep for everyone else
now the aggresion yes, i would take it to the pound and tell them its a hard dog and if they cant find a rightful owner to do what they gotta do
