Bryan Breeding prefers little dogs.
Dogs should be at least one year of age and in good health before breeding. In my opinion, one litter a year is healthy for a dog. And breeding should stop when they are over 6 years old.
yeah
is dog breeding an example of natural selection

There are no two dogs that are good for breeding, they all are, it just depends what you want the end result to be.
