I can be anti-social at a times when I feel a need to be, but I am not exactly an extrovert either. I definitely do not lack empathy toward others...but I'm still a dog person. I have found (and in my opinion based on my experiences) that dogs are the most interactive animal with humans on the planet, other animals are to an extent but dogs are more so. Raised and trained right, they can make wonderful non-human companions, there's a reason they've been given the title of "man's best friend" when no other animal has.
