When we first got the dog it walked just fine with a collar and leash. Then seemingley overnight, the dog won't budge. I refuse to have a dog and not be able to take it on walks or anywhere that require a leash. I have a GSD puppy and it will need to the exercise and will get so big that I won't be able to carry it. What do I do?

Most puppies will respond to getting out in front and coaxing them. If not, try dropping back behind them and running past them in baby steps while calling ''Go, go, go!'' in an excited voice.
