Hahah ehm.... no idea. =S I am sightly allergic to dogs (used to be much more allergic as a kid), but I'm ignoring that fact since I love them so much.

Luckily it has worked out really well with my dog that I've had now for two years. Not too many symptoms, and nothing I can't deal with. However, my point is, the fact that I am allergic to dogs (and to some much more than others) was always something that lay heavy on my heart when I grew up... I couldn't believe how unfair life was, that I would have to be allergic, when I loved them so much. Not just dogs, but other animals as well.
With this in mind I HOPE that people don't use this as an excuse for not liking dogs and cats.... =( It's okay not to like them (even though I find people who don't like animals rather creepy, haha), but don't use allergies as an excuse.... since actually having allergies REALLY suck.
But so no, not everyone with pet allergies are pet haters. =/
