yorkie pregnancy behavior!

Question
Our female yorkie was breed on 2/23/09 before that she was always as sweet as could be! But now she wants to fight her sister every chance she gets! can you please tell me if this is normal? or should we be very concerned and consult our vet? Thank you!

Answer
Hi. Hormones will cause all kinds of problems.:-) It's most likely that your girl is pregnant, and her hormones have kicked in. Sometimes, girls will get pretty cranky or their normal behavior will become opposite of what it normally is. It's most likely normal, but if it would make you feel better to have her looked at, then I would take her in for a check up. Good luck!
