Such cuteness!!
Remember though, danes, pit bulls and many other breeds that are classed as bully breeds, come from similar stock way back when. When pups are young, they are harder to id than when they're say, 6 months old or older. Ever had a batch of puppies with unknown parentage that were less than 10 weeks old? They're hard to tell what they are unless the fur is really diagnostic.
I will forever know what a chow pup looks like though. One big ball of fluff!!! :D
