Kaley Cuoco-Sweeting knew her husband was 'The One' because he loves animals.

The 'Big Bang Theory' star, who married tennis player Ryan Sweeting in December after just six months of dating, admits she fell in love with him when he bonded with her pets, but joked the real love of her life is in fact her pet pooch Norman.

The 28-year-old actress said: ''I couldn't have been with someone who didn't love dogs. He let ours sleep in the bed!

''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!''

The couple also have five horses but Kaley is the only one brave enough to ride them.

She added to Us Weekly magazine: ''He wants to pet them. He doesn't want to ride them.''

The actress also previously said she believes her dogs have prepared her for parenthood because they've made her more responsible.

She recently said: ''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.

''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.''
