I agree with behavioral problem. It sounds like the dog has way too much energy and is excitable. This may sound dumb, but do you ever watch the show "Dog Whisperer"? To me, giving up the dog would be like giving up an unruly child. Just my opinion. The training process will take time and effort on your part but hopefully be rewarding. If you don't want to buy books or DVD's on training, how about research at your local library? Best of luck and please keep us posted on how it is going.
