1st time dog owner here....

I've been researching and reading up.
I'm curious - how much do you guys care about the history if the pup.
I found this working punchlist which seems like ALOT to ask from the breeder ......but I don't know if all these questions are really relevent or not.

Thoughts, suggestions, advice ?
Is there really that much of a ~keen eye~ involved when you see the litter and pick out one ..

So this is what came up under Google...

1. Is the breeder registered with any national level kennel clubs?
2. How long is the breeder in this trade?
3. Does the breeder have any testimonials about the female and male ?
(In my case, I have one breeder who has 2 week litter and 6 week litter. Not sure what the mom/pops. In the latter, I have another breeder who just bred, said about 3 months out, both mom and pop are show winners. It's not that I really care whether the mom and pop are show winners. I'm not looking to compete
4. Is the mother registered? What about the stud?
5. How old is the mother now?
6. When was her first litter? How many litters has she had to date? What are the time gaps between the litters?
7. What is her health condition? Did she suffer any major problems in its puppy-hood? Adulthood? During the pregnancy?
8. If yes, how does that bear on her progeny?
9. Does he/she have any news about the puppies that had been sold previously? Does he keep track and contact of the people who buy the puppies?
10. Why they are breeding this breed of dog? How long they have been doing this job with this particular breed.

The answer to these questions will give you sufficient clarity on the quality of the breeder you are interacting with. There are other telltale aspects:

1. Check out the place where the mother and the puppies are kept – check it for comfort, cleanliness and lighting.

2. Insist of taking a close look at the mother – is she underweight and pathetic looking or is she exceedingly glowing with happiness and contentment.

3. Find out whether you can be referred to any of the past clients of the breeder – you could find out whether the puppy has fared well or not.

4. Insist that you see the complete check up medical certificates of the mother to find out whether there are genetic defects and serious health problems.
