when I started with Huskies I was told a zillion times my dogs were not purebred........ (hold for it)........ because one was bieyed......( one eye blue one brown)...... that was their purebredness hint...... .. and literailly i did what i just did with the smiley thing...... and kept going my way.......

there are some traits as mentioned longer fur, longer legs, more narrow snout, broader heads, smaller ears, etc....... but that just are genetic things that some poorly bred dogs may have but they are still purebred....
