Sunshine - Your posts present such a target-rich environment that I don't know where to start.
I would like to familiarise you with a logical fallacy called Straw Man - it is what you do when you misrepresent what people have said and answer stuff that nobody claimed, such as Cote why are you so determined the dog meat trade is a lie? or Why are you so determined to believe that a Vietnanese girl wouldn't weep over losing her pet? which of course I have not said or implied in any way.
"if you think at this is not one if the thousands of dogs stolen and traded for meat, because the photo shows no evidence of that, what do you think happened to it?"
It looks like a dead dog - that is all I know. That is all you know as well, despite your pretensions of prescience. FWIW, the dog doesn't look cooked which you would know if you had ever seen an animal cooked whole. There is no indication whatsoever that this photo was taken in a market of any kind, least of all a meat market. You are filling in all those blanks with your fiery agenda, or worse, your gullibility.
"Dog meat sells more (VND per kg) than any other meat. It's stolen so no rearing. costs and sold at a premium"
... which makes it understandable that people in Vietnam are stealing & selling dogs. Do I need to tell you again that GDP per capita is $1,900 in Vietnam? That is about £1,200 per year. If people kept ducks or sheep for pets, I bet those would be stolen and eaten, too.
"The problem is not poverty. The problem is that people who love their pets are gutted when those pets are stolen'
You are confusing the overall problem and its side effect. The problem is poverty. That is why thieves are stealing dogs to sell. The side effect of this theft are sad kids, which, in the grand scheme of things, I really can't get that outraged over tbh.
In places with low income, hungry kids (of the thief) trump sad kids (who lose a pet). I am really surprised that an adult needs to be told this.
