Who? Where??

When selecting puppy do puppy test, when selecting dog do dog test loh! OK! seriously, I don't know what you are really looking for. Different types of dog test for diffrent situation. In order not to go too far ahead I would generalise that we want to see confidence in a dog, good nerve and temprement and clear headedness. React only under threat. When you are into training then you will see it and knows what I mean.

Who is the apek you mean? Me? You test before you buy not buy then test. I think you terbalik liao.

Good breeder tells you the line(not that everyone know how to appreciate) Sometimes they advertise on their site or such. Let say if you do come to me as a buyer asking for a whole bunch of papers. I would say thank you very much. All my pups are already sold.....pun intended. Reason being
1) do your research and by referal of another of this breeder before you approach him you should already have some basic knowledge of him.
2) do your own study and decide if you have the confidence on a breeder before approaching him
3) have a sincere conversation to ask for anything you don't understand
4) never sound like you don't trust or doubtful of their lines.
Remember, good breeder breeds out of passion for the breed. Money is not the most important thing for him. He don't have to make that sale and believe me if he sense any doubts or not sure of anyone, he won't be selling.

Kowpa does have his points. All in the eye of the beholder. You must decide if you want to spend 100K on a kick ass dog or 1K for a mongrel? All I can tell you is that show dogs puppies go for 1800-2500 as a general market price. Working dogs all depends on the drives.
