Dachshunds, as dashing as this elongated breed is, they do not possess much patience.

Giant Schnauzers can be quite a domineering breed; so much so that they often challenge not only their owners but other people and dogs too.

Miniature Pinschers can be quite Napoleonic in that they suffer from the Òbig dog-little bodyÓ complex. In order to accommodate for their height they show many aggressive tendencies.

Old English Sheepdogs are perfect for the owner whoe wants to feel adored and protected. If this dog even thinks someone is in too close proximity of their masters, they will deliver some aggression to drive their point.

Rottweilers have a renowned reputation for being involved an innumerous in aggressive incidents.

Pekinese has its share of mood swings.

Toy Poodles can be quite squeamish. As a result, they quite often misconstrue playfulness as a threat, meaning they strike out via biting.
