I have three dogs and two cats, who all get along together. In the evening, they will all hang together with us. They all drink from the same water bowl. One of my smaller dogs will groom the cats and they seem to like it. My other smaller dog is the leader of the pack. He is a Yorkshire Terrier.
My largest dog of the three dogs is a 80 pound, Belgian Malinois. His dad is the highest ranking dog in the history of that breed; conformation dog. I was fortunate to get him. He gets the most liberties, since he is the smartest. He allows the older 15 pound Yorkie, to lead the pack, out of respect for him. The Yorkie is a good leader. The Mal does not want to make waves, and does what it takes, so everyone can get along.
The Malinois knows the time of day and keeps see on my schedule, especially if he is part of that schedule. He acts as my personal trainer, when we go for our off lease walks in public spaces. He is my point man and will go ahead to sniff forward. If I stop, for any reason, he will backtrack to stand near me. After a short rest, he will insist I get moving again. If I sit on the ground, he will get under me, and pry me onto my feet.
This breed was originally bred to be a herding dog. It now is used as a working dog for civilian and military K-9 and personal protection. Where we walk off lease, he takes it upon himself to be a liaison with other dogs. He likes to meet and welcome new and old dog friends. He will even try to teach some dogs better social skills, if they are disruptive. The other dog owners don't seen to mind, since their dogs respond well to his training. He has even taught several dogs to walk off leash, to the delight of their owners.
The police in our town have the same type of dogs for their K-9 patrol. My dog is known to the police for his role in escorting my late mother, who wandered, because of her Alzheimer. He would walk with her, if she left the house, and would remain until the neighbors called police. He would protect, but also know when to her turn over to the police without being overly protective. Back in the day, he would also act as door keeper; unlocked door, for the various medical and insurance related people who would come to help my parents if I was at work. He would meet them at the door, smell them, and if they passed muster, he would disappear. He did not micromanage. They all accepted his role.
At one point. I thought I was losing my sight in one eye, so I started to train him to also be my future seeing eye dog. My eye was fully corrected with cataract surgery, so those skills are no longer stressed. Now he is semiretired. That is a lot of like about dogs and cats.
