You are about to have the time of your life!!!! Congratulations. Cannot wait to see the pictures of this little boy.
Just be prepared to know what to do in case of emergency, map to ER vet, a few emergency responses - all those things, not to be negative but you want to be so ready for everything, including safe transport in the car, etc., just like with a baby!
Keep your camera near you always as all of these early pictures will become priceless before too long. Yorkies change appearance so quickly so having lots of baby pictures all along is so much fun. Get someone to take pictures of you with your baby, too, as sometimes we don't have nearly enough pictures of us
with our little ones as they grow - and much later, you will wish you did. Be prepared for the first bath when that time comes down the road and try to stay as relaxed as possible during it as it can set the tone for how they react down the line.
Hope the wait is not too awful for you as the clock ticks very slowly when waiting for a Yorkie!!!
