Thank's to both of you for your input. I have been googling away, and have found some useful info, however, I have not found many photos. That white spot on the one female's chest is just eating away at me because, although I used a breeder whom is well known in my area, and has been called reputable by several people that I have spoken to, I left my female there for 2 days. They had a little, mostly white with a little brown terrier of some sort, maybe a Staffordshire,running around whom I was assured was neutered, and would not even have access to my dog. I have preoccupied myself with what-if's, and unnecessary conjecture. It is of some comfort to read your response's so, once again, Much Thanks!
