For five years, while we were living with my mother-in-law, my husband kept talking to my daughter about getting her a dog of her own. Our family dog really belongs to our son. SO, when we moved, a month after we moved, we went and got this LARGE puppy at the local animal control.
Training, or re-training, a dog sized animal is harder in some ways than training a little puppy. Their potty training accidents are larger. Their mouthing issues pose more painful consequences for the trainer. Their jumping on visitors habit is worse because they aren't a tiny thing that only comes up to the knees; they can get face to face with a guest pretty quick.
All that being said, he is a really sweet dog and very smart. I think he's going to be a comfy addition soon.
