Did you get go introduce them before the adoption? My female came with me to get Midnite. Same thing as you, he wanted to play, she snapped at him. She also gave me dirty looks all the way home. They got into a small tiff within a couple weeks and after about a month they became best friends. Lots of time, patience, and supervision and they will be fine.
