All THREE of our dogs are quite plainly MY dogs.
It is plain they love the family. They love to cuddle with anyone, play with anyone, get excited if anyone comes home, etc. Keoki has to sit on dh's lap every night to sleep and snuggle. But if I leave the room and he's awake enough to realize it, he'll jump down to follow me.
BUT, They usually need to be in whatever room I am in. If we are outside walking and someone else has the leashes, the dogs have to keep stopping to make sure I am still w/them.
If I am in my bedroom with the door shut, all three will wait in the hall until I come out.
My kids feed them, work w/training, etc. so I don't know why. Although I was told that it is because the dogs perceive ME to be the pack leader and so respond to me as such. Whether fact or fiction, I don't care – it's a fun thing to point out to my husband on a regular basis --even the DOGS know I am the REAL boss of the place. LOL
