@Ionus,
As no one as yet had been stupid enough to send agents of the government under the color of the law into people homes to seize their dogs in order to kill them in a wholesale manner so you are not going to have civil war with blood running in the street because of an event that had not happen.
Now however I will list the reasons why I think that if the government ever was stupid to do what you seem to wish them to do the lost of lives would dwarf the harm done in yearly dog attacks within days or weeks of the start of such a program.
There are a fair percent of people who do not care for the government now and are also heavily arm and this had results in some not all that small blood baths here and there in this country already.
My example that was given was for the purpose of pointing out that such a blood bath had already been trigger by the killing of a boy dog when they was out for a walk.
When you are talking about tens of millions of family pets it would take only a very very very small percent of the owners willing to used deadly force to protect their pets from the evil and this case stupid government to have blood running in the street and that bloods would not all be of the pets and their owners bloods either.
It been over 18 years since I lost the last dog I had bonded with however I could not off hand see myself standing by and watching her seized to be kill under the color of law in order to satisfy some PC nonsense.
You would be as safe in fact coming into my home to seized a child to kill as coming into my home to seized a family pet to kill for no good reason and this degree of bonding if uncommon is not all that rare.
My prediction is that there would be thousands of deaths all over the country and you might not call that a civil war but it is near enough for me.
