After, supposedly reading about how purebred dogs are becoming more inbred and unhealthy, one person pointed out the the dogs she had as a child lived to an old age, and so did the next one, and . . . then she did get one that died young, and then . . . (sounds like she is an older woman)

But puppies can have puppies when they are a year old. That dog she had as a child?

He could be 70 dog generations ago - as far removed from the puppy of his breed that she could buy today, as you are from your ancestors in the year 500.

Dog breeds are not carved in stone. They are like the sea, always changing, yet always the same.
