<human>: Give me the gist of the text in a nutshell

Hi everyone. My husband and I got a puppy last year (she will be 11 months by the time of the event I am going to be discussing). Every July, my in-laws host a huge family reunion at their home where family from all over the county come and stay in their house. Due to conflicting schedules, my side of the family is having their July family vacation (going up north for camping/boating - can't bring her with us as my parents don't allow dogs on their boat :() during the same time. We are going to be spending 4 days up north with my family, and then 4 days at his parent's house. We have never put any of our dogs in a kennel, as his parents always watch the dogs for us when we go out of town. I am nervous because while our puppy is pretty good about listening to us when she is inside, she sometimes likes to run away (she loves to be chased) when outside. His parent's house doesn't have a fence. People will be coming and going in and out of the house all day long and I am terrified that she will escape and get hit by a car. 

Does anyone have any advice for things we could do to keep her safe? 

Thanks for reading/responding!
