| Not only should the dam and sire be spayed / neutered, all of their offspring could be carriers and should be spayed / neutered as well ... and not only from this litter but also previous litters.

There is dna test for D locus to determine which dogs are carriers of the "d" allele | |

| I’m hoping you are referring to any puppies from that mom and dad because both parents have to have it in order for them to have a blue born puppy so both parents need to be fixed.

| We don't yet know the outcome of the genetic test on the little one. Then, I have couple of questions. 1. Breeding Pairs. I've read and re-read the article published by Animal Genetics, "D-Locus (Dilute Coat Color)." See the chart "Results" toward the end of the article; it describes three outcomes to the D-Locus test--D/D, D/d and d/d. If a D/D is paired with a D/d, is it true that the offspring can be either D/D or D/d (but not d/d)? If a D/D is paired with a d/d, will the offspring be either D/d or d/d (but not D/D)? 2. Pending return of D-Locus results, what if the three-week old pup's coat has changed from blue at birth to black and tan? Thank you for your input. Last edited by KatysMom; 05-15-2018 at 06:24 AM. |

| Bit more on testing. For those who, like me, would like to see more testing done (in general), Animal Genetics will accept either "a dewclaw or blood" sample from very young pups. See "What is the best kind of sample to send for testing?" at "Frequently Asked Questions (Canine)." |

If a D/d is paired with a D/d is it true that the ouffspring could be D/d, D/D or d/d? Have I missed any permutations? | |

| It's a simple punnett square https://en.m.wikipedia.org/wiki/Punnett_square DD + Dd a non carrier (DD) + a carrier of the recessive (Dd) 50% Dd 50% DD If both parents are carriers there is 25% chance of a non carrier puppy. If both parents have expressed the dilution gene, meaning they are both (dd), then all the resulting puppies will be (dd) as they (the parents) don't have the dominant D to pass it to their offspring. DD + dd All puppies will be carriers of the recessive (d) Last edited by Mike1975; 05-16-2018 at 07:33 AM. |

Yes, I am referring to the pups and relatives of the parents. Both parents are definitely carriers of the ressecive d, so no test is needed. Also the blue born puppy is definitely dd. | |

Update. Deb's little one, now a good-sized black and tan, is happy and healthy. She had the vet test for DNA, heart, kidneys. All good. No dd in the DNA. Deb and her whole family have fallen in love with the little guy. He couldn't be in a better place. Last edited by KatysMom; 06-05-2018 at 06:24 AM. | |

| Blue puppies With all the colors popping up, blonde, merle, ocean pearl, etc. in the yorkie universe, you can't assume that a puppy born "blue" has the "blue puppy" syndrome. Things aren't as they used to be; but DNA is a great resource. |
