I'm not exactly sure how my opinion on this subject relates to Orthodoxy, but my understanding is this in relation to canines: the domestic dog is not the product of natural selection, but selective breeding by man. In most breeds, we have removed many of the natural, God-given instincts and traits of wild dogs in order to make them more useful or enjoyable to humans. We have even created breeds that would have absolutely no chance to survive in the wild (see the "toy breeds" among others) that frankly wouldn't exist without the influence of man. Because man essentially "designed" these animals for our use, it is our responsibility to care for them, and controlling their population when we live in a culture that considers them quite disposable is essential to prevent further negelect and abuse.
