I know some people like to suggest that it's because they've been raised vegan but I've never seen any evidence for that. It is odd though.yeah I just saw that! what a non surprise, Also I don't get how the mum didn't immediately realise it was the dog, aren't pretty much all people with asmtha allergic to most dogs and cats?
I have no idea about the allergies thing, it is weird, I know a couple of people with lots of allergies but none of their siblings have them
