^ It's Kibi and Dango, the two dogs she bought recently. Her mom lives in the same building as her so she must be taking care of the dogs while Ayu is touring.
I'm super free and bored now so I decided to compare the pictures she posted inside her house and the one from a collection. And we can imagine how big her backyard is lol (it's the same marble so it must be from the same area in the house):
