Dog Behvior

Question
Do certain dogs tend to be more aggressive to different breeds than others? E.g say the Pekingese is not good with the Great Danes? Would this ever happen?

Answer
no-it seems to be more of an individual thing,and I haven't seen two breeds that don't generally get along with one breed and not another

However it seems like a lot of dogs don't like pit bull,or pit bull type dogs as well as other fighting breeds,as they may give off aggressive signals to other dogs

But say a beagle won't hate border collies unless he hates dogs in general

And sometimes you have big dogs that don't like small dogs or vice versa
