To the best of my knowledge this breeder only breeds two breeds.
I being, somewhat anal and also older, keep very detailed records, and would never think to get to the serious point of offering for sale a dog I was not up to the minute on in terms of their health.
Now this is an older dog ~1+ yrs old, supposedly held back for show, but "grew" a bit to0 big and so they were looking to place her in a home.
The point is not how many dogs they have (well at least for me) but why were they so un-professional in not reviewing the records a whole lot earlier when offering up this dog for placement?
So an educated and professional sort could show an in depth knowledge of each litter but have only one litter a year or 20 litters a year.
