Each male is marked with a color. The color is the ribbon that we have on that puppy to help us keep track of who's who... with 11 puppies and a little sleep deprivation they all start to look alike. If you are interested in a particular puppy please reach out and just let us know the color of the collar and we will be able to give you all the info you need on that puppy! Text is always going to be the fastest way to get a hold of me but feel free to email or call if that is more convenient. My cell number is at the top right of all the pages and my email is at the bottom! For the link to pricing and deposits head to the bottom too. We will be posting new photos as we take them for each puppy so always check back in to find more individual photos of each pup or check us out on Facebook at Roslyn Labs.
