The 29-year-old former cast member of Saturday Night Live was seen visiting Citipups in New York City to pick up his new pet.
On Wednesday, the pet shop shared a video of Pete and Chase, both 26 years old, working the counter on Instagram.
The couple, who started dating in late 2017, could be seen grinning and nodding as they talked to a store staff.
According to TMZ, they went to the store on May 21 and bought a cavapoo puppy.
The Cavapoo is a hybrid dog that combines the traits of the Cavalier King Charles Spaniel and the Poodle.
According to reports, Pete called Citipups ahead of his trip to express his affection for the cavapoo after seeing a picture of him.
It's reported that the King of Staten Island star fell in love with the puppy so deeply that he bought him right immediately and brought him home.
