I found myself forgetting the topic when I read this post, because these are many of the traits that I like to a certain degree! :rofl1: Isn't it amazing how everyone can find a dog that fits them, even when their wants are completely different!? I'd have to say human aggression/reactiveness. Any dog that doesn't happily let a new person into the house when you give an okay. Boo barks incessantly at one particular individual when he comes over (she's afraid of his guitar case), and it drives me insane. Otherwise, she's perfect. Also extreme dog reactiveness/aggression. I can handle a dog that gets upset if an overly pushy dog gets in their face, but I wouldn't be able to handle having a dog flipping in circles at the end of its leash at another dog. and yapping. A dog can have a voice... but there is a time and a place to bark. Not at the wind/leaves/birds/squirrels/people/everything it wants or sees. and, in the case of different breeds, I wouldn't want a breed that is so weirdly shaped that it can't breathe or move correctly.
