Scarlet is a cutie whatever she is! If you have a real interest in learning what she is, I would recomment wisdompanel.com - there you will find a site that will send you swabs for her cheeks, then will later on send you a report showing everything that is in her, and how much of each - it goes back five generations and the reports are wonderful. I know I sound like a commercial, but we sent off to find out what our Gemma was mixed with, and found she is basenji all the way on one side, and sheltie on the other, with a little collie thrown in three generations back. Because the reports send along information about what the breeds personalities are, it's really easy now to see when Gemma is being sheltie-ish and when she's being basenji, which is mainly when she's interacting with her PB sister. Good luck with Scarlet, and welcome! I think you can also pick up the DNA kits from wisdompanel at PetSmart, or so someone told me.
