Former Friends star Jennifer Aniston's love for dogs will always win hands down when compared to her affection for men.

"Men come and go but there really is no relationship like the one you have with a dog - and then they don't live as long as they should," sources quoted Aniston as saying.

Aniston, who is currently dating rocker John Mayer, owns two dogs named Norman and Dolly - and admits nothing can match the companionship of her faithful hounds.

"You have to say goodbye way too soon. It's just so sad. It makes me so sad. But their love is unconditional and I love that," she said.
