Jennifer Aniston's dog, Norman, is having some trouble adjusting to her new boyfriend, John Mayer, the Daily Record of Britain has reported.
Aniston, who just finished filming the movie version of the popular dog book "Marley & Me," reportedly keeps the two apart when Mayer visits the actress's Los Angeles home.
"It's funny because John likes dogs but for some reason Norman has taken a disliking to him," a source close to Aniston told the newspaper. "Jennifer dotes on Norman and treats him like a child. But she has got to the point where she's had to keep him out if the way if John is around the house ... Norman is just picky about people."
Aniston and Norman, shown above in a 2005 Elle magazine spread, have been constant companions for years and apparently Norman has yet to bond fully with her the new boyfriend.
Aniston and Mayer have been seen taking Norman, a Corgi-Terrier mix, for walks, apparently so the dog can get used to the singer on neutral ground.
