Dogs don't really bug me, but owners do.
Not in terms of biking, but I tend to not like little dogs in general. We have a dachsund at home that is awesome, but we also have a ****zu-Poodle mix that I loathe. She eats grass and vomits everywhere, which in turn stains her beard hair and makes her smell constantly...she barks at anything, waking up my 1 year old daughter from her naps, won't eat the food given to her but instead steals everybody elses and is generally a huge PITA.
Anyone looking for a small dog?
