Forgive me but in the first picture I didn’t think Kira was a dog😂. I don’t even know why that came into my mind.

she is the daughter of my daughter's pet and in turn the granddaughter of my brother's pet

That’s literally family connected with family.😂 if I am ask, does the dogs see each other from time to time. Or maybe your brother doesn’t leave in the same country as you do.

she also receives visitors in the living room House.

Because of the fear I have for dogs I might think that your dog is trying to bite if it tries to play with me 😂. But I think I might be attached to your dog because of its Color(at least its not black)

As a puppy it looked really really cute 🥰 I must say.

when I am sick she does not leave my side and is there taking care of me

When you are sick she in turn plays the motherly role. That’s nice. I hope I can find a dog who will treat me like this even when I fall sick one day.
