I think it's very rude! Chloe and I get it ALL the time
They always ask: how much she weighs, is she a teacup, where I got her, how much she costs, how old she is, and will she get any bigger.
A lot of people don't even ask those questions, they just assume. "Oh my! What a beautiful teacup Yorkie. She must be a puppy! How old is she? 2-3 months? Will she get very big? I bet she was expensive!" UGH! Then I have to give my teacup lecture
One man at the pet store recently, leaned in to Chloe (to "pretend" whisper) & said "Tell your Mommy to take that stupid crap [bow] off your head & to stop dressing you up!"
I could NOT believe it...I wanted to kick that man's butt.
