I'm hunting for a pup for my mom who has fallen in love with mine on her last two visits. I have found a pet quality pup here for a very fair price, but was a little concerned about the white on the chest (see picture). Is this something that happens and is an anomaly or is this pup probably not a purebred. I was thinking I had read before about some purebreds coming out with white on their chest, but couldn't find it. Any info would be much appreciated.
