Just because a pup looks like one parent or the other, does not mean that it is a 'pure' animal and not a hybrid. It is possible that females can have a litter with multiple sires- it'd be cool to do the genetics to figure out, but as Colin states, it does happen in some shark species.
Pattern is just one in a series of traits that can be passed down to offspring and you cannot tell for sure who the parents are based on pattern. Think about people- one parent can have blue eyes and one parent can have green eyes- you will not be able to tell who the father of a child is based on eye color!
