Advice on finding the best homes for my dog’s upcoming litter General Chat

my 4 year old Belgian Malinois was impregnated by a male black lab. I want to make sure that I get the puppies to the best homes possible, how can I go about ensuring that these puppies go to loving homes that will give them a great life. Any advice would be very helpful. I will certainly be keeping one of the puppies so any tips on what I should look for when I select will also be helpful

I am located in Southern California
