Your pups are adorable! I just saw your post and don't know if someone has addressed it yet, but as bad as it may sound to some, inbreeding in dogs is how you get desired traits. I breed and show chihuahuas and my male is very linebred (which is the same thing as inbreeding, just goes by a different name) and he has all the desired traits for my breed. As a result of his breeding, he passes on his genes to his offspring, and he has produce several champions. I have a current litter that is 14 weeks right now, and with the linebreeding you don't know if you are going to double up on the good or bad genes. Out of this litter I have two puppies that are show hopefulls and will be starting their show careers soon, and one pup must have gotten a double shot of the bad genes and he has a longer nose, shorter skull, and his eyes aren't as round as I would like. He is going to his new home Sat on a neuter contract. But basically what I'm saying is no, there is nothing wrong with inbreeding in dogs as long as it isn't mother to son, ect. One more link out is fine. Yes, breeding merle to merle is bad (there is a huge debate going on with the merle chihuahua right now so I am very educated on this subject) but make sure you get the pups eyes and ears tested. It the pup is mostly white, and has white covering their ears most likely they will be deaf.
