In 12 years of raising Yorkies I have never had a female attack a male, not even when they are pregnant. I have had females fight amongst each other. How big is your female and male? I did hear one time about a female dog killing a small stud dog when the female was in heat and the owner of the female left her alone with the stud dog that was a loaner. I am sure it is just a hormonal thing but it is wise to keep them apart. She will probably be even more protective after the pups are born. |
