Kaley Cuoco-Sweeting's love of her life is her dog.

The 'Big Bang Theory' actress married her beau Ryan Sweeting last December but she admits there's someone else who holds the key to her heart and that's her beloved pooch, Pitt Bull cross, Norman.

Speaking to E! News, she said: ''Anyone that knows me, knows Norman and he is the love of my life. My husband knew that going in. He's number one, he's the apple of my eye ...I love that guy so much!''

Meanwhile, the blonde beauty and her husband, who first started dating in June 2013, are coming up to their one-year anniversary but they are yet to make any plans to celebrate the milestone.

Asked if she's made any arrangements for their anniversary, which falls on December 31, she replied: ''Not yet. We're so excited. I can't believe it's been a year. It went so fast. So I'm really excited.''

The stunning star, 28, who recently claimed she was ''born to be a wife and born to be a mother'', believes her dogs have prepared her for parenthood because they've made her more responsible.

She said previously: ''I think if you can take care of a plant, then you can take care of a dog and then you can have a baby. It's all in the order.''

She added: ''I can't wait actually to have kids surrounded by all the dogs at our house too and the horses, and raise them with animals and [show them] how to treat them correctly. It starts from the very beginning with puppies and with babies, and showing them how they need to be treated.''
