“There is no way on earth that euthanizing a dog with a knife can be reasonably justified as economically expedient.”
Unless you don’t have access to the killing tools which shelters possess.
My mother runs a shelter.
I just laid out $73 to tranquilize and euthanize a 18 year old cat. Mom's shelter is a “no kill”, which means she contracts out the kills to local veterinarians.
There really is no such thing as a “no kill” shelter, just one that shelters until a off site humane mechanism becomes necessary.
I have seen hundreds of cats, dogs, sheep, horses, bovines and even alpacas put down. Always a little late (IMO) and always in humane manner at much cost. I do not consider shooting an animal inhumane as a method. Killing with a blade however is another thing. Maybe I am just a sissy
