Cute puppy! Get a book and read is the best you can do if you have never owned a dog before.
This is one of the best books out there:
Dr. Pitcairn's New Complete Guide to Natural Health for Dogs and Cats
I did this and 8.5 yr later my Newfoundland is still the healthiest Newfy around
. Follow the advice is all I can say.
