While it may seem cute when a dog mounts a motorcycle helmet and makes pelvic thrusts, I think it reveals a lot about the inadaquacy of the social environment the dog is confined to. Without a doubt we see happiness in dogs under human management. However, we also see happiness in humans in prisons, wars, factories and other repressive situations. Therefore, I would not say the existance of happiness is sufficient reason to manage animals. My sense was that they were bored not calm.
Many people genuinely love the dog in their apartment.
So, even though the dog has been cut off from significant contact with other dogs, even though the dog's reproductive system has been cut up or cut off, even though the dog cannot urinate when it wants to, even though the dog is held on a leash when taken out, love and genuine good intention abound. It is a wonderful thing that love can penetrate into these dark corners. We can stop harming pets. That would be the fullest expression of our love. I think that love for animals is something that pops up quite naturally.
