Leave the dog with your parents, where she'll be free to run.
Dogs have short memories. We like to think that they miss us, that they'll remember us after even a week apart, but the fact is they only think about food.
When you come back, your dog will treat you like a stranger.
Don't be offended. She's just a dog, doing what dogs do.
But she's been accustomed to running free. That a dog doesn't forget.
