I can see why nutrition and health care are important concerns, but how do those other things make her a better brood bitch?

They are all important in different ways. The most important is probably the last one. Pregnancy, delivery, and puppy raising are very stressful on a dog and knowing that you love her really does make her job easier.

For one thing, she'll trust you to help with the puppies, rather than feeling that she needs to defend them. The obedience training comes into play in the strangest ways. Sometimes a female will get overly anxious when her new puppies start crying: being able to put her on a down stay so that she is giving them ready access to what they want (food!) will give you great peace of mind.

These are just a few examples of why all this preparation is important. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
