Your dogs might be an object to you, but they aren't to many dog owners, it isn't uncommon for people to nearly kill themselves over their pets, or in times of crisis like floods or fires, for owners to grab their pets over their material belongings.
And everything you describe about dogs, I'm sure for the right price you can buy and sell children, get them killed or even eat them in some countries, doesn't make it right.
It isn't hard to find a flat that is dog friendly, to dump a dog onto someone else for this reason alone is so heartless. It is totally NOT like swapping your big couch for a smaller coach when moving flats.
What a stupid and ignorant statement HC.
In certain parts of the world HUMANS are also bought and sold. Most rightmided people find that objectionable, and refer to is as slavery.
In certain parts of the world HUMANS are also eaten. Most rightmided people find that objectionable, and refer to is as cannibalism.
As for your point about putting sick dogs down, I am not sure how that is at all relevant to the initial post, other than perhaps you trying to upset people, but if there is something relevant on this point please do clarify.
