Welcome to YT!!! I feel you about going nuts! My baby is only 2 weeks old and I have a whole lot of time to wait and go crazy!
I am a novice at Yorkies, but I have been doing my research. According to the Yorkie growth chart, your baby should weight 2.5-3lbs full grown. This is definitely a teeny tiny baby. Your breeder should have all test results and a vet card with shot records to give you. Here is some info about vaccines that I found online:
Puppies (6 weeks to 1 year)
6 – 8 weeks………. first puppy shot (DHLPP) + Corona
11 –12 weeks……. second puppy shot (DHLPP) + Corona
15-16 weeks……… third puppy shot (DHLPP) + Corona
over 4 months…… Rabies ( repeat 1 year later)
7-9 months……… first heartworm test
Adult Dogs (after 1 year)
DHLPP…… Yearly
Heartworm Test……Yearly
Rabies……. Every three years (after 2
nd shot)
Bordatella….. Yearly
I hope this information helps!
