The health is the most important thing.
Look the pup over careful. Does he have a clean coat free of fleas and ticks. Look at his ears, are his ears clean inside. Look at eyes, they should be clear and alert, not watery or dull looking. Look at nose, make sure the nose is not running. Watch the pup for a little bit. Make sure he is alert and active, you want a happy healthy puppy, not one that is sick. Also, ask if there has ever been any health problems with puppies from a past litter and if this puppy has any health problems that you should be aware of.
Also, check out the living conditions, it should be clean and a good place for the pups and adult dogs.
Look at the disposition/temperment of the parents. They should be nice and friendly, not aggressive nor very fearful. Same goes for the pup.
Ask why she is letting the pup go at 8 weeks and not keeping him any longer. I like to keep any pups until they are 12 weeks old or 2 pounds.
Are the parents 5-6 pounds or is that the weight of the puppy?? If that is the weight of the puppy and he will only be 8 weeks old, you are going to have one really big puppy. A standard yorkie is 7 pounds and under, you definately would not have a standard yorkie, he would be over 10 pounds when full grown if that is the correct age and weight.
That is all I think of right now as to what to look for.
Good Luck with the pup, I hope everything works out for you!!!
