Your best bet is to buy a copy of "The Book of the Bitch" will is chock-full of essential information for any bitch owner. Also a few books about the breed would be invaluable too - no research is ever wasted. No offence meant, but I suspect you may not know a great deal about the breed, or you wouldn't call her 'golden' - there's no such thing as a golden labrador! They come in three colours, black, yellow and chocolate.
Basically, your bitch will need to have a satisfactory hip-score and a current clear eye certificate from a qualified ophthamologist. She will need to be between 2 and 4 years old for her first litter.
Remember there are over 45,000 labradors born each year, and there aren't that many suitable homes available, so think long and hard before you add to the numbers.
