Pat and I both have had females as old as 14 months and as young as 6 months having first heat cycle.
I have the vet X-ray my Yorkies' mouths before we remove any teeth to make sure there is a permanent one underneath. Several years ago, the vet extracted a permanent tooth and Midget had a little space where the tooth should have been. Can you believe it? She needed 10 teeth extracted and had only 1 perm. in the front and it got pulled.. |
