I get the same sense that you do--dogs (and pets in general, it seems) have definitely elevated in status in the past ten years or so. Witness the inexplicable rise of not one but (at least) two huge box-store franchises for pet care (PetCo and PetSmart, in other areas there might be others). Not only that, there are now psychoactive drugs being given to pets who are "depressed," or, laughably, "obsesive compulsive." Other personal stories:
1) Some time ago a man had committed a vicious crime against his dog. Lawmakers were considering making this specific behavior by owners a punishable offense with its own set of consequences. What was this unthinkable act? Leaving his dog on a leash outside for more than 24 hours.
I'm not old at all, but I can remember a time when dogs were outside more than in, most often on a leash. Now obviously such a great percentage of dogs live inside that it is considered abuse to keep them out. How did this happen?
2) I overhead a young veterinary student on the bus talking about animal abuse. She said that she did not feel as bad for children who were abused as she did for animals who were abused. Her "rationale" was that children could speak for themselves; animals don't.
I was flabbergasted when I heard this. Here, someone was openly admitting that they valued the well being of animals over human beings. Worse, the person she was talking to reacted as if this was normal.
I don't know how to explain this behavior. I suppose one could look to the erosion of the family, etc, but I'm not sure. It's amazing, it really is.
