yorkie male get pitbull/lad mix pregnant

Question
can a male Yorkie get a pitbull/lad mix pregnant? my lad is in heat and my yorkie won't leave her alone. I'm scared that when I'm at work they might do somethings they should do. is it possible that the yorkie can get her pregnant without help being as small as he is?

Answer
Hi Christina. As a matter of fact, he can get her pregnant. Small male dogs have been known to get Great Danes and other giant breeds pregnant. The female may squat or law down for him. My best advice while she's in heat, is to keep them apart. Good luck!
