Phil Mia died early this year from heart condition, she was 1 years old. (She was a very very special girl, she was Lynzy in a dogs body)!!!

Interesting did she have a Baer Test done? My ancient memory is jogging here, the white piebald markings often linked to deafness? Not sure just a question.

What heart condition did she die from?

Here is a quote from one article about deafness in dogs that have the piebald (sp) gene. This is the color gene carried by Biewers and Dalmatians:

From Genetics of Deafness in Dogs

Genetic transmission of deafness in dogs with the piebald (sp) and extreme white piebald (sw) pigment genes, such as the Dalmatian, is less clear. These genes affect the amount and distribution of white areas on the body. Deafness in Dalmatians does not appear to be autosomal dominant, since deaf puppies result from hearing parents. It does not appear to be a simple recessive disorder, since we have bred pairs of deaf Dalmatians and obtained bilaterally hearing and unilaterally hearing puppies, when all should have been deaf if the disorder was recessive. These findings might be explained by a multi-gene cause, the presence of two different autosomal recessive deafness genes, or a syndrome with incomplete penetrance. Further studies (in progress) will be required to determine the mechanisms. Several candidate genes known to cause pigment-related deafness in humans or mice have been eliminated as the possible cause of pigment-associated deafness in Dalmatians. Whole-genome screens will hopefully identify the cause in this and other breeds.

Here is a link to more information about deafness in white spotted dogs:

Deafness is related to white pigmentation, because melanin is required in the ears for hearing.

I could not open the 2nd link might be my adobe, I will check. Mia2 who is sister to Mia1 has the unbelieveable pink skin too but she can hear, so far no health issues.

Thanks for the reading material I want to understand this.

p.s. do you think her heart disease was in relation to the deafness? Stupid question I'm sure...but just curious if you've heard of that combo.

I hope you're able to open the second link--it is to a website devoted to deafness in dogs and is quite good.

There is no such thing as a stupid question. I did a search for any relationship between white coat color, deafness, and heart disease, and found no connection of heart disease to coat color or deafness. The heart disease is probably something that developed separately. Sorry for the loss of Mia 1 .

Thanks Phil. For sure you are a Godsend, when my aged memory, and my sad lack of search skills combine. I was pretty sure there was a deaf/piebald link.

Heart disease is also twigging here, although I did read you researched and found no link... to deafness; but how about albinos? This might be a wives tale I heard 30 or more years ago.

No I couldn't find any association of heart disease with albinism either...

I am not sure if this applies in this case but there is a connection with deafness and heart disease in humans. This is the article I read a few months ago. I did not believe I kept the link but here it is if anyone is interested:

Something You Don't Hear Much About: Hearing Loss Tied To Heart Disease

Humans and canines do share a small percentage of genetic material but what are the odds it would include this. The article is from 2005 so maybe there is current information. Just thought I would share it.

Thanks for posting that Tricia. Interesting stuff. for sure.

I'm about 10 years late but I made it! I have a blue merle. If you are still out there, here's some pics!

There isn’t such a thing in Yorkies. Is the dog registered? If so what registry?

[WheresGA]

Ckc registered

[matese]

There are two CKC

CKC-Continental Kennel Club or

and


CKC-Canadian Kennel Club


Which CKC is your "Blue Merle" registered with because there "is" a deference.

Not a reputable USA registry. Mixed breeds are registered as full breeds with it every day. Sorry to say your dog is mixed with another breed. Again no such thing as a Merle yorkie.

Still love him and do not care! thanks

I’m not downing your pup I’m just saying there isn’t such a thing as a Merle yorkie so it must be mixed with something. I have two girls registered with the ACA that is not reputable both are bigger at 17 and 12 pounds with floppy ears. I also have a 10 pounder with a full tail and no papers. The only point I was trying to make was that there is no Merle yorkie and yours isn’t reputablely registered so it’s probably a mix.
