It happens. . . people have babies and are unable to take a dog at the time, therefore stay on the list or drop off, families run into health problems, divorces, people walk into a shelter and fall in love there, etc, etc. I just know so many reputable breeders who have lists but sometime, SOMETIMES, they DO and CAN fall through! It's really never happened to me where I was left to have to advertise my whole litter but the odd time I have had to place an ad for maybe one or two puppies of a large litter. It's never been a negative experiance for me so I guess I don't understand but I do hear what your saying. You can NEVER be too careful!
