Sorry JeanieK to go OT here but wanted to address 816Tuesday's misconceptions regarding why breeders microchip.
USDA (commercial) breeders are required to keep identification records of their stock. Collars, tattoos or microchips are used. Microchips are inexpensive and permanent, tattoos are more time-consuming and difficult to do, collars (little paper tags commercial breeders use) aren't reliable, as they tend to deteriorate, fall off, get lost, etc. The only "microchip agenda" with commercial breeders is; they are supposed to comply with USDA regulations and it's the cheapest, easiest method.
I don't know if most U.S. exhibitor/breeders microchip but if so, would imagine it is so any puppy they've sold (if lost) is identifiable.
I don't believe there is any microchipping "breeder agenda" but do have my thoughts regarding
your agenda. 
You advocating microchip removal by pet owners is not only dangerous, it is sick!
