Yuki is a shy and timid boy but he loves other dogs and will slowly open up to adults. He loves toys and Is picky with food thus he is on a home cooked diet. He can be overly excited when he sees other dogs on the PCN but he listens to corrections well. He does sometimes throw tantrums when he is left alone esp if there's no one else (other pets) to accompany him. He is also very smart and will bully you if you don't discipline him.
