The unfortunate reality--of selecting for harmful deformities, generation after generation, for purely aesthetic reasons--is quite a bit more gruesome.
I don't make any arbitrary distinctions between companion animals and other animals (people balk at harming cats or dogs, but pigs are at least as smart and 1.5 billion of them are slaughtered per year, with millions more destroyed for all sorts of reasons), nor do I see the value in having intermediate classifications between person and object. As far as I am concerned, either it's a person (a distinction not necessarily limited to humans, but most-capacity based criteria effectively rule out non-humans), in which case it should not be owned in any sense, or it's an object fully subject to ownership.
Personally, I tend to anthropomorphize my animals and treat them as people, but I cannot rationally expect others to view them the same way. Fortunately, they don't have to; all they need to know is that my animals are property I value and that I feel entitled to defend my property by any and all means at my disposal.
Laws on the topic are often inconsistent and poorly reasoned, arbitrarily elevating some animals above others, generally being based on prevailing cultural mores rather than any attempt at empiricism. Enforcement is equally arbitrary and frequently absent...often only brought up as a pretext for harassment or investigating/penalizing unrelated crimes.
I understand some of your points.
But destroying a pet, no thanks.
Farm animals for food consumption, are killed according to standards predefined by professionals (in general, peasants, slaughterhouses ...) and regulated by the law.
And although I don't like slaughterhouses, this is the world, unfortunately.
Killing a pet at home is the door open to all abuses and perversions and tortures.
We start with the animals and we continue with the children ?
Now in France, a person who tortures an animal (cat, dog, bird ect ...) is severely punished by the law.
Can even go to jail.
