PLEASE DO!!!!

And it would be more perfect if we knew who the breeder was & what she's going to do about further breeding.

Did they (Mars) cross reference or somehow obtain the DNA results from AKC that does have DNA information on purebred Yorkies?

As a breeder, of a Rare Breed that is relatively new, I would expect to get some very small % of non BRT if I was to do a Wisdom Panel test - but then again, I doubt very much if they have many BRT's in their database.

I do agree with some other posters here, that the breeder should refrain from mating that particular pair again.

I also think that the breeder given a pup that seemed so far off the breed standard would have DNA'd the parents to make sure that pup was from those parents. If the answer was yes, then well and good, and at least a comment from the breeder to the buyer about how far off standard this puppy was.

It is quite sad to see so many Yorkies that look so far off standard.

What is important is that Minnie is in a good home.

Those are all fantastic questions!!! MARS has a FAQ page that answers some, but not all of these questions: http://www.wisdompanel.com/why_test_your_dog/faqs/. They do accept DNA samples of purebred dogs to add to their DNA database, so I emailed them for their information packet on how to do this, and I am going to submit a DNA sample from my Bella . I also asked them how many Yorkies are in their database, and are they all AKC registered. I will let you know what I hear back from them.

Pardon me for mentioning this, but...and I know I am not a geneticist nor a breeder of the Yorkshire Terrier...but it is my understanding that recessives only express when a homozygous gene pair exists. Otherwise, when a heterozygous pair exists, the recessive gene remains visibly 'invisible' unless it or a modifier can create a 'blended' outcome.

So, if short hair is dominant, and long hair is recessive in the Yorkshire Terrier, then wouldn't all Yorkshire Terriers with long hair be, by default, homozygous for that recessive gene pair?

If so, how exactly, without a mutation or modifier, or non-Yorkshire Terrier in the immediate parental mix, could two (2) homozygous recessive long-haired dogs produce a dominate homo-or-heterozygous short-haired dog?

Side note, I just looked at pics again...Minnie really is a doll, but I still don't see Yorkie, I'd really like to see results. I know of 2 black labs that had a white curly puppy but even that pup grew to look like a white curly black lab, if you know what I mean...this pup doesn't look like its growing up to look like a throwback Yorkie...I'm having a real difficult time with this one, really want to see those results....Wonder where Baboon is? hmmmmm

She was last here at 12:15 today. Guess she is still trying to post some pics for us of her breeding pair.

Sorry lynzy! I was not reading every thread....just kind of skimming thru to get kind of caught up...been a rough last 7 days around here.....in addition to the events with the fire and Memorial and funerals and emotional melt downs, my beautiful Skylar, who was not due to whelp until TOMORROW, delivered her litter prematurely, day 56, last Monday.....around the clock tube feedings every hour to every 2 hours....but, with the Support and Strength and Grace of God, we have made it thru on ALL fronts.....Jimmy is doing well with getting a grasp on the loss of his dear friend Robert.....just gone from THIS "visual present" but not from "the Other Side", where the Angels are ever present....and the precious little preemie babies, that started off at 1 - 1.5 oz at birth, have thankfully turned the corner and are doing great....I think they have survived this challenge, PTL! Onward and upward!

Don't worry, Judy, you are not the only one who doesn't read every post nor do others. I frequently see the same idea posted more than once and have done it myself and others have posted ideas I've mentioned. Don't feel bad.

I'm so glad your Jimmy is coming to terms with his friend's death and I imagine it must be so hard for him. Sounds like you've been through a lot with new babies! Hang in there!

Thanks for the link. I looked at it, and could not help looking up my breed BRT. First no National Club should have supported that narrative or that picture. Some facts are relatively correct, but YES the BRT has a standard appearance as is supported by the many breed standards throughout Russia, America, and Canada.

That standard appearance does not include a sway back with a roached sacrum and a low set tail. And if they had asked the National Clubs or any country for input, this dog can do many things and does. Service, drafting, bomb detection, police work (in at least one USA state), dock jumping, herding, water rescue to name just a few arenas they are in. They can be trained for search and rescue, but their size is an eliminating factor for many organizations that do search and rescue.

Their topline is very important and MUST BE straight. For a whole lot of very valid working dog reasons. And BTW so should the YT's topline be straight.

Now if it is indeed true that the Mars organization is using an "adhoc" database to compare new DNA samples with; that just boggles my mind.

There is an old saying; Garbage in, Garbage out....... So if the database is sourced from suspect sources, how can they realistically improve on their analysis?

So maybe their science might be the best out there, but judging soley upon what they reported as the BRT, it is very incomplete and in-accurate to say the least. That makes me question, their methodology, their commitment to accuracy, and any and all results they might come up with.

Hey you guys, im back for now. So whats goin on, im a bit confused.

I was curious about the Mars stuff quite some time ago. I have been there before, but didn't stomp around in their website all that much on prior occasions...mostly I looked at what tests were offered, what the reports looked like, what tests were for what, and what, in general, to expect to discover. It seemed pretty cool, all things considered.

This time, I looked up the Yorkshire Terrier and was surprised to see that included in "related breeds" to the Yorkie, along with Maltese, Havanese, and others I do not understand, was a "Greyhound" breed. Very curious...and I did not see any elaboration as to why they consider the breeds "related" either...but I suppose we are expected to trust the testing...?

Surely u know I was kidding? Judy very glad things r turning around and the grace of God was once again at work...I wish and pray for only good things...

I did but Judy sounded kinda serious I thought maybe she was having a bad time today. Sounded kind of down.

Good question! Either the breeder lied about the appearance or identity of Minnie's parents (i. e. one of them was a heterozygous short-haired Yorkie), or Minnie underwent a spontaneous mutation early in her development and acquired the dominant gene in that way (in which case she would be heterozygous). A third possibility is that Minnie's parents carry an unknown recessive gene for short hair that hasn't been widely published on. I searched the literature and didn't come across anything, but that doesn't mean that such a gene doesn't exist. That's why I encourage Minnie's breeder to stop breeding her parents.
