I feel the same about dogs honestly. I prefer older small dogs because I find that when they do cross my boundaries I'm less likely to be injured in anyway. I honestly dont know how I would be able to live with large dog. Its funny that you say that cats cross boundaries a lot, because my experience has definitely been the opposite 😅 a dog is the size of a person too. When those cross my boundaries I usually get physically hurt. I suppose the experience of other people must be different lol
