ALEXANDER star Rosario Dawson has a tough time with her boyfriend JASON LEWIS' dog whenever she walks him - because he attempts to have sex with everything he comes across.

The actress is currently looking after Lewis' two pooches as she shoots the movie adaptation of hit musical RENT in San Francisco, California. And she's found 11-year-old KNUCKLES to be a real handful at times.

She says, "Knuckles gets really excited... He's like a little puppy and he humps things when he gets really excited, like most dogs. But it's cute, though, 'cause I'm just not used to havinga dog.

"There was this one time we were playing - and he really likes retrievers - and he just jumped on this dog's face! He didn't even bother to go around the back, and I was dying laughing.

"I was like, 'This sexy dog's just going at this dog's face!' I just thought it was the funniest thing in the world, but the owner of the other dog didn't think it was that cute."
