There are some wonderful breeders out there. Send an email or call. They are very helpful and willing to answer your questions. I did my research though. The wonderful YT helped. What to look for. That is how I learned the breeder was not being as fair. I like the fact that some actually tell you how they evaluate the puppy. Helps me understand reasons for why. Knowledge is key
Good luck in your search. You will find the right puppy for you.
