If it's an older dog, 7 you said, it will probably be pretty calm.
It doesn't take much to lay in the corner of my couch and paw and whine at me for love. I sit on the floor in the middle of the couch and if the dog is to my left she made me scratch her chest head back I'd even massage her back legs. She was spoiled. And when I was gone she chilled all day.
My mom has Alzheimer's so my dad and I are going to take care of the dog together so the dog shouldn't have to ever be alone but in the beginning I'm going to train her or him at my home cause I can't have the dog shitting over there. My dad has enough to deal with
