Dog meat being eaten is also a common thing here in the Philippines. But we also do not want it. Though we are not vegan, like you and your whole family, we have dog pets and we treat them as part of our family.
I guess I can't say whether it's ethical or not, but in some cases there are dogs raised for meat only. This is not as bad as stealing someone's pet, but something about farming dogs for meat just feels weird to me. It's all relative though, many Slovenians and northern Italians grew up eating horsemeat burgers, something very strange to the average American.
