There is no problem with dogs being possessions.
I can't even talk to you. You're spewing ridiculous jibberish. What on earth can you bring to the table to back these babblings up? And if it involves a chapter and verse reference, save it for the tourists, padre.
It has nothing to do with religion, Smoo. Is a dog a possession or isn't it? If it's not, what is it?
It's a viable self-sustaining lifeform. Humans have decided to trade them as if they were possessions, just as they used to do with African humans, but that doesn't make it right or definitive.
Is it wrong to trade them and treat them as possessions?
I think it's wrong, yes. Not nuke-Europe wrong, but definitely squish-bugs wrong.
Well you haven't given any statements to back that up, other than saying that they have internal organs like we do.
Why is it wrong?
For many of the same reasons you people worship humans. They're life.
Just because they're alive doesn't mean it's wrong to trade in them. We buy and sell lots of living things, from dogs to plants to yeast cultures in yogurt. Is it wrong to buy yogurt??
Ideally, yes, but at some point two other concerns enter into it (I've said many times that it's impossible to isolate any single variable)...
1. Practicality. It's difficult to track, protect and save yeast. It's less difficult to track, protect and save a dog.
2. Food. As valuable as life is, it's an unavoidable fact that life has to consume other life to live.
But those are obviously tougher questions. To paraphrase Maurile, recognizing the value of a dog is not.
