Just be careful if you get a new dog while your kid is at college.
My mother and stepfather did this. They got a new puppy while I was away, and it slept in the kitchen, with a gate across the doorway. It would not allow me to get past that gate. I mean truly would not allow it. (The dog was a Doberman.) It considered me a stranger and treated me accordingly.
If I wanted a snack or drink at night and there was no resident family member available to restrain the dog, I would have to drive to McDonalds.
