My Chloe had an accidental litter with my friends black & tan Chihuahua. The puppies were gorgeous & very sweet. We gave my mother in law pick of the litter for Christmas, and this puppy is the light of my in law's life now! She (my mom-in-law) calls and updates me every week how she does in puppy class, claiming she is the smartest one there and most social! Everywhere she goes people want to keep little Bootzee. She sure did potty train a lot easier than any of the full yorkies I have ever had! Don't know if it is due to the mix of breeds or just a great pup. I say go for it 100 percent!
