Thanks, everyone.
It's been an education, for sure.
She was brought in from the country. Chances are a miller-puppy from the little bit of history I was able to catch on her.
She was from a litter of 12..
Only her and her sister had not been chosen. It sounds like a broker situation. Her sister had 'too broad of a head'..
and she had "too long of a nose". Both rejected. Both sold off, then rehomed... then rehomed again...and again. I was told she's been through at least four homes. But all seem to be in the same general area. Perhaps, it was well water or some other system.
Genetics could be right too. She's certainly a poorly bred Saint. (Although, she has that drool factor down to a "T"!)
I'm not sure about how she was fed, other then the woman who surrendered her, most likely fed her kibble. She's spent her whole life in a kennel. Fed and Watered twice a day.
That's all I have for now. She's doing wonderfully, so far and has not only adjusted to living inside, but LOVES it so much she's reluctant to go outside unless one of us is out there too.
