That's terribly sad:( Your sweet border collie is a dollbaby:)

That is sad very sad! Your Grace is sweet

i saw this on fb too.
they are located in czec republic i think it says.

Merle Chihuahuas are beautiful.
 

If you breed Merle to merle that is a very bad thing. to many health problem's They probualy bred her to a Merle Chihuahua.:p
Anne/Luci:animal-pa

The breeder finally admitted they are chi mixes.

4 generations back bred for the color back to yorkies...no such thing as a merle yorkie they're selectively bred chorkies...

This breeder even after admittibg it later tried to deny it, therefore I don't view her as reputable she only admitted the liniage to thise she thought would be interested in breeding the in Ametica getting them AKC recognition...this is fraud IMHO.

I'm glad the off standard color breeders took no interest, they are only interested in actually natural occuring yorkie color variations

I can send anyone the links if you want proof but only privately, its not appropriate to promote another forum on YT.

Actually, akc doesn't offer Merle or blue as a color for chihuahuas. At one time they had to have been bred to a breed that commonly carries a Merle gene.
Shelties, dachshunds, heelers and other breeds carry this blue and liver colored dappling. Chihuahuas, yorkies and other dogs are not supposed to be "blue". Breeders breed for this (not reputable breeders) for $$$. They call them rare, jack up their price and don't give a damn that the dogs will suffer.


M-Locus
Merle
~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
The merle phenotype is treated as a dominant but is actually a incomplete dominant or a gene with intermediate expression trait, with heterozygous dogs presenting a coat colour in which eumelanic regions are incompletely and irregularly diluted, leaving intensely pigmented patches. Merle is found throughout the body except on the pheomelanic regions of the black and tan coat colour.

The Merle gene has been successfully identified on canine chromosome 10 and located on the "pmel" gene.


The merle phenotype is very old, with the merle coat colour being reported in old books from which drawings of merle dogs have been selected and reproduced.


mm - Non-merle


Mm - Merle - This is another dilution gene, but instead of diluting the whole coat it causes a patchy dilution, with a coloured coat
becoming patched with a lighter color. IE. - black to Gray, blue to lighter blue, Red to lighter Red, Brown to lighter brown.
The lighter areas are the actually merling and not the darker areas as many seem to say.

Eyes of an Mm dog are sometimes blue or merled (brown and blue segments in the eye



MM - Double Merle - Considered to be SEMI-LETHAL as 1/4th of all MM puppies are born dead or have such severe

abnormalities that they die shortly after birth. A MM is a double dilution of the merle gene spotting the same

area causing that given area to actually turn white. Thus double merles are a mix of 3 colors.
Double Merles are often confused with the Merle/Piebald combination.


Merle appears to act as a minus modifier, in addition to its effects on coat color.

M: Merle series
homozygote MM - Double Merle - produces double marked merle areas of white - possible health issues.
heterozygote, Mm - Merle
mm = no merle


One parents has to be merle to produce merle offspring as it is not carried recessively.

I don't know if that was for me or just based on my comment, either or that was what the breeder had expressed interest in doing...her words not mine.

Personally I find it as I said just plain fraudulent as she continues to call them purebreds stating their chi liniage has been 'bred out'...and if she sells chorkie as yorkies who knows what the supposed chis really were either...

Oh wow, and there are some who will "buy" that. :p

Yep... Just like those rare "teacups" and "micros" that everyone wants to buy.

Than u all for this helpful info

oh the "infamous" MERLE thing.. let me just say merle is a BAD, BAD thing... that is all I have to say..

Greed gets people . . .

Blue born yorkie puppy is not merle. It is something entirely different.

By the way, The Chihuahua Club Of Canada which is the parent club for Chihuahuas here in Canada has gone through all the steps to put a DQ on merle coloured Chihuahua's. It has beed passed by the Canadian Kennel Club and not only can they not be shown, merle colour puppies cannot be registered.

Exactly so sad!
I wasn't sure someone else posted that info. I just know what I have read about Merle's and think its terrible.
