On the first day of Maltipoo adoption, my daughter called him "Mongmong

We went to the dog center to just take a look, but there was a dog that was particularly welcoming to my daughters by waving his tails.
The cat-loving father wanted a cat until the very end, but eventually adopted the puppy his daughters wanted.
On the spot, My daughter gave him the name 'Mongmong' and ordered and made a house for 'Mongmong'.
Maybe it's because he's a smart kid, so he has successfully started to toilet from the first day of potty training, and 'Mongmong' sleeps in his own house even though we didn't let him in.
He is my 3rd child.
