yorkie heat I need to know if my yorkie has come into heat. she is 20 mo. old and as far as i can tell hasn't come into heat. She gets very friendly with our cat and licks alot about every 4 mo. or so, but doesn't have any significant swelling or bleeding that I can tell. I want to breed her, but am not sure what to do since I can't tell if she is in a real heat. help |
