For his costume, the man, Toko, commissioned a Japanese company called Zeppet, which specializes in sculptures and models for movies, commercials and amusement facilities as well as TV costumes and mascots. The costume reportedly took 40 days to create. Toko also went through multiple rounds of revisions, including meetings and fittings for the costume.
In an interview with Mynavi, Toko explained that he chose a border collie costume as the long hair can “mislead the human figure.”
“I made it a collie because it looks real when I put it on. My favorite is quadrupedal animals, especially cute ones. Among them, I thought that a big animal close to me would be good, considering that it would be a realistic model, so I decided to make it a dog,” Toko said. “I met such a condition and made collie, my favorite breed of dog.”
