Training should not cause head injuries!

Taking Gilda into my life has been a blessing and a challenge. She is such a happy, good natured dog. She has moved in and settled down into our lives like she has always been here. The most amazing thing is her sweet, trusting nature towards me. For a dog who was abandoned by her owners and locked in a cage for who knows how many days, she sure was quick to trust a stranger.
This has been even more evident the more that I have taken her out. She is very wary of other strangers, and will either hide behind me or take a defensive posture- growling and barking at anyone who comes too close. But then she will sigh, lay her head in my lap and give me "I love you! Thank God you are here!" look.
Whatever the reason, this dog chose me the day she followed me out of the woods, and I am honored that she did. I've grown to love her just as much as the rest of my wild brood.
But all of her energy and zest for life does make her a challenge- I can see why someone couldn't handle her. Doesn't make what they did OK, not by a long shot. They should have researched their dog breeds better, and gone with a more laid back breed.
So, now I have this very exuberant dog to train. Now, with Luna the first thing we worked on was 'sit.' When she would obey this command, I would jump up and down and say "good girl! best girl ever!" Her whole face would light up and she would sit as hard as she could to keep getting praised. With Gilda? She is learning to sit on command, however her response to praise is to launch herself strait into the air and lick me in the face, knock me down and roll around on the ground in delight. Wagging her tail all the while. You gotta love her, but wow.
I get the feeling that life will never be the same.
