Hi and Welcome to YT!
Kobe's very cute! Good pics! Congratulations!
There's a thread on insurance... here's a link:

Lots of info in the YT Library...
There's info on vaccines in the Library as well...
Kobe should have a fecal done. When he gets vaccinated, only get one vaccine at a time, and space them 1 month apart. Keep him in the house until his vaccine schedule is completed.
The BAT is the Bile Acid Test, which tests for Liver function, is used in diagnosing Liver Shunt and other problems, and is not very reliable until pups are older (4-6 months). The vet can check for LP on physical exam, again when he's older.
As long as he's eating and drinking, I wouldn't worry too much. If he's having any problems, discuss them with your vet.
Sorry I couldn't be more help....
