Breeding is someting you do to aide in the creation of the dogs you want or just to see what comes out. Sometimes by accident and sometimes by very careful study and design. 

When we bred it was because we had a great bitch and access to a great sire. The litter was a good one and had some surprises. There were not ulterior motives other than to see what the litter would be and go through the process.

It was not that expensive and endeavor and having the pups and watching them grow was awesome.
