A very old stray {The Old Fella Story}

It's supposed to be in the 70's today after a cool, wet day yesterday. Susan, I took the food away immediately after the tussle, and have been encouraging her to eat it right away. So far, she seems to be doing much better, although she finishes the food (about 1 1/2-1 3/4 cups twice a day, as much as Dash), and then looks for more. She does love to eat, which explains the fact that she is somewhat overweight. The biggest problem right now is she tends to growl at the dogs when they get near her, which is especially odd for Lily, who is not dominant and has done nothing but try to be friendly. I think it's the Husky part of her; it only happens around the house, and she is trying to establish dominance, a trait I encountered before with a Malamute. She needs to learn quickly that I am the pack leader and I make the rules. Probably, a little training, even a refresher obedience course, would be helpful in this regard.
