You know it really amazes me how ignorant and stubborn some people can be.
I tried once to explain to someone that her yorkie wasn't a special breed (teacup) that they can come in all sizes and colors but they are still only one breed but that didn't get through.
Thankfully I've only run into a few who refused to accept advice even though they obviously know very little about the breed and then you just want to wring their necks, lol.
Fortunately most people I have met are very open to learning.
