i think he calls whomever is closest to, to tell him about his pet. even though i'd had a dog for weeks, after hikaru went to friends or crush (can't remember which) haato called him to tell him about the dog.
I mean, I called this dog(shiba inu) as "Shiba", and when Haato called Shiba and said that he adopted a dog AND gave it his name, Shiba was surprised and blushed . Too much Shiba :D
