Question for breeders or...
 
Question for breeders or those who know about Yorkie genetics:

I recently adopted a rescue Yorkie that has flesh colored eye rims and lips but a black nose. She has some itching and hairloss that the vet attributed to allergies, but in my research about allergies and skin issues I found out about the condition called Color Dilution Alopecia (CDA) and I am now afraid that it may be what my dog has. I would like to know two things:

1- Does the fact that she has flesh colored eye rims and lips mean she automatically has CDA?

2- She has some hairloss on her head which is blonde not blue. Does that rule out CDA?

Anything you know for sure about the condition may help in some way so I welcome your opinions and advice.

I honestly thought about returning her to the rescuer but my heart won't let me, so now it is all about helping her feel better (and if possible, look better too).

I will post pictures separately.

Are you sure that her nose is a dark jet black and not dark blue? Dogs with color dilution alopecia usually have dark blue noses. The light color of her fur certain looks like this could be CDA. The blonde hair on the head does NOT rule out CDA. The mutation that causes CDA lightens the color of the hair and skin, but it does not change the hair color. There is genetic testing for CDA, so that is something that you should definitely look into. Here is a link for a company that does the testing. The cost of the test is $80:

Here is a link to an article about CDA. If you get a referral to a veterinary dermatologist, they will be able to do the necessary testing and let you know for sure if this is CDA. Good luck, and keep us posted!

Here's one more article:

Definitely see a veterinary dermatologist to get an accurate diagnosis, because there are other things that can cause baldness in Yorkies that are more treatable, such as allergies, ringworm, etc.

If it does turn out to be CDA, don't worry too much, because your dog can still live a full, healthy life. You would just have to take extra steps to maintain her skin and keep her comfortable. Thanks for taking care of her!

Here is a link to a veterinary dermatologist in Guaynabo who might be able to help you:

(I know that part of Puerto Rico like the back of my hand :)).

Thank you so much for your responses. I will definitely get her tested now that I know who to go to. As for the nose, i put it next to my Schnauzer's nose and they both look the same shade of black. Could it be that they are born with a blue nose that turns black later on? She is currently 10 months old.

That's possible--I've only seen photos of dogs with CDA, and some of their noses are quite dark in color. I hope that the dermatologist is able to figure out what is wrong with your dog and is able to treat her so she is happier and more comfortable! Keep us posted on what you find out, because this information will help others with the same problem!

I called the place but the secretary who answered the phone said they don't do that test there. She said she would call me when she speaks to the doctor to see if he knows where I can get the test done.

Okay. Besides the DNA test, the doctor can also take a look at the hair follicles to help figure out what's going on. I'm sure the doctor will have more answers, but the testing site that I provided a link to will do the test for $80, and I believe that they send you a DNA sample collection kit so you can take the sample yourself and mail it in. It's probably a cheek swab, very easy to do if you follow the instructions, and they will either mail or email you the results, and you can take those results to the doctor. I would recommend making an appointment with Dr. Marcos Vega so he can examine your dog in person, because her condition could be due to something else besides CDA. Keep us posted!

I would def go to a Vet Dermatologist as soon as you can as the fur loss could be from so many other things...hypothryoid, allergies, skin infection, Cushings, ring worm, malnutrition. A derm will at least be able to help with those first 5 things...either diagnosing them or ruling them out.

For hair loss in Cushings dogs, they are given Melatonin 2x a day and it does help a ton! Ferrets are also given Melatonin for fur loss. So, I'd be sure and ask your Vet Derm if Melatonin would help w/ whatever the fur loss is caused from in your kiddo.

UPDATE: To all who replied to this post, I am happy to report that Mia is slowly but surely re-growing her hair, AND she's going blonde! I put her on one of those hair re-growth products (Don't know if it's ok to post the name) and it is working. I no longer think she has CDA, although she does have allergies and apparently, a weak inmune system, as she also caught a fungus out of nowhere that made her lose some of her new hair. But fungus is taken care of now so we are hoping she'll re-grow it again. It's only a little patch about the size of a quarter. We changed her diet to grain-free and chicken-free, including treats, and she is no longer itchy. She is growing little hairs in the back of her ears, which were completely hairless, and basically has little hairs everywhere except where the fungus got her. We are also giving her vitamins to strengthen her inmune system. I will post a picture so you can see what she looks like now.

Here you can see she has a little bit of hair on her torso, minus the spot where she had the fungus.

And here you can see where her hair on her head is turning blonde.
