You mean like how I had to bite my tongue when a lady in my puppy class was bragging about how her Rottie puppy was expected to be about 140 lbs when full grown? And they just can't figure out why he's limping so much at such a young age? I know stuff. But I agree with Dizzy - there's something that that person knows that I don't know, and I would hope they wouldn't bite my head off about it or talk to me about it in a condescending manner. That being said - I've learned alot assisting with public training classes at my club. People and their lack of knowledge about a LIFE they are caring for doesn't surprise me anymore. I help as much as I can, and I hope they take my advice.
