It can be a bit daunting raising a pup from a young age... My advice is to read .... then read some more...
Then keep reading until you feel you have enough knowledge to write your own book!
Being educated whilst raising a pup will make things an awful lot easier for you and the little guy.
Oh and stay away from cows milk.... the wee fella's cant digest it properly and its nutritionally inadequate. Goats milk is good.
Like the others have said go to your vets now... it will do no harm and he/she will be full of helpful advice. Also taking your pup to the vet for the first time without him recieving a treatment can make future trips to the vets easier as the pup will not associate discomfort with this first trip.
Good luck with the little guy!!
Oh and here's some info to start you reading
