People never cease to amaze me with how rude and annoying they can be! I don't know anything in particular about Newfs, but a dog that is 80 lbs at 9 months sounds huge to me. Also, she's one inch away in height from the breed standard for a female? At 9 months, she's nowhere near finished growing, right? Well, that is beside the point - she's your lap monster regardless, and you love her. You'll laugh that you wrote this when, in 6 months, she's like a zillion pounds. Think of some kind of witty response for the nosey know-it-alls. Or, just go for blunt honesty that makes them feel like jerks, like "Yes, she is purebred, and she is perfect just the way she is!". Or, "Thanks for being so concerned for Sierra, but it isn't necessary, I assure you." Or, "I'm happy that you're intrested in Sierra, but your questions are becoming nosey and offensive so I"ll be going now". Or, "Oh yes, she IS mixed with Chupacabra, and she will eat your face off if you don't get out of mine. Buh bye now."
