Pups learn a lot the from their mom in the first 2 months. Although not by choice I was left with a newborn Chi @CBC birth. Had to bottle feed it every two hours and take care of its diaper needs. Needless to say, she doesn’t know she’s a dog.
Oh, geez. DROID freeping sux.
I read that mama dogs know which puppies are preset to be alpha dogs, and they are sterner with them than with the less dominant pups : Growling at them when they get too pushy and so forth. Humans see this and think the mama dog "hates" that puppy, and so "rescue" it-making sure the alpha puppy never learns good dog manners as it would have if left with the mama dog, and so becoming more likely to be a discipline/behavior problem for their human family.
