I laughed at the political insert, but there are some dogs that have absolutely no use to humanity. Putting them down is the most beneficial to all.
We have always had dogs we have 4 right now, Over the years only 2 of them have been problems. And no amount of training or money spent or time invested cured their habits to a trustworthy status. One chased horses rather riders were on them or not. The other nipped kids. Both of which I came very close to shooting, The 120lb female Malamute that nipped kids, I should have shot her the second time it happened, as the guy that we gave her too that promised us she would not be around kids ended up biting a relatives kid..He then gave the dog to some guy living on 100 acres in Eastern Washington under the agreement it was not to be around kids.. The wife and I both wish to this day we would have just put her down instead, as the potential was always there for this dog to seriously harm someone much more valuable then that stupid dogs life was ever worth no mater how beautiful she was. I shake my head in total dumbfoundment at those whom dont get that concept.
I have put down 3 dogs 2 cats and two Horses..a tear always comes to my eye, but those were out of mercy and beloved friends of the family. I would not have given a seconds pause to have dispatched the other two. They were wasted space on earth.
