It seems like her dogs = her whole life, aside from working on music and all that. That's how it seems to me - she's with her dogs all the time, becouse who else can she rely on? Who else will be there with her for good and bad?...

If you're a megastar, you have to work - that means writing lyrics, recording, filming videos, commercials, doing photoshoots, appearing at promo events, rehearsing for and doing lives... Do you have some time inbetween? No. Becouse you spend all the time inbetween on traveling to all the places where you need to go to do all that work - to recording studios, filming studios, photoshoots, on location, to all the places where events are held, to rehearsing studios to practice for the lives...
You're basically in movement all the time, the only spare time is probably when you go to the hotel for sleep - and even then, you can't do much aside from sleeping, becouse the more things you would want to do, the less time you would have for sleep and rest.

She probably checks into her own place like few times per a week and she can't stay for coffee and some cookies, becouse there's constantly some work to do. If she wasn't bringing her dogs with her, she would barely be seeing them.

And if you're a megastar, you barely have friends, becouse it's hard to make friends with people who are in different environments and who go through different things. She's a solo performer, so nobody except her knows what it's like to do all the performing work, maybe except her dancers - who do know that one part of her career, going onto the stage almost everynight for few hours, dancing in a souna-like space and sweating so much you're soaking with perspiration. The band would also add up to that list along with dancers. But Yo-chan can't be with her all the time, neither can Naoto or Midoring - while her dogs can.

She definately goes paranoid over her dogs, after all, they're the only ones around her who don't get paid for being with her, and since people can get emotionally bound to an animal, especially a doggie, who knows if she doesn't percept them as the only true and honest beings around her... I wouldn't be surprised if Nagase left her becouse she spends more time with the dogs than with him.

I'm sure part of her staff is simply hired to take care of her and help her when she's working and I bet that includes taking care of her dogs as well - not like the bath them or something, but they definately have to keep an eye on them.
