What color is this newborn?

My friend is a doberman breeder and her fawn doberman just had a litter of doberman puppies. I went over to visit her and took a look at her puppies and she said she had four black and 6 fawn. I thought the "fawn" puppies looked blue, especially next to the fawn mother. They had a silver look to them. I am sure she knows more than me, but am I right or is she?

Pups look blue to me.

Is this the breeder's first litter?
Im no expert but next to that momma they sure look blue to me.
The ultimate test is nose and paw pad color, but it's pretty obvious these puppies are blue.

Yes. She has bred mastiffs and boxers before, but her first litter of doberman. But glad to know I'm not going color blind!
They look blue to me. Do you know the color of the sire and whether he has been tested to determine his color's genotype? This would help determine if it's even possible for him to produce fawns.

When bred to a fawn, the following genotypes cannot produce fawn pups:

black #1 BBDD = 100% black #4 (BbDd);
black #2 BbDD = note that with this breeding, the statistical expectation is 50% black #4 (BbDd) and 50% blue #6 (bbDd), which is very close to the 4/6 split in this litter*;
ETA: black #3 BbDD = 50% black #4 (BbDd) and 50% red #8 (bbDd) [but doesn't apply to this litter, as we know 6 of the pups are dilutes]
blue #5 bbDD = 100% blue #6;
red #7 bbDD = 100% red #8 (bbDd);

(Please see the DPCA's Color Inheritance Chart for more info.)


------------------------
*This litter's phonetypic 4 black/6 blue split, since until we know (or can deduce through parentage or previous breedings) the sire's genotype, we can't really know the pups' genotypes without testing their DNA. Kind of a convoluted sentence, but I hope it makes sense...

Ooops. That's what I get for trying to say two different things at the same time. :oops:

Anyway, to clarify, the genotype of a black pup produced by a fawn parent can be only black #4/BbDd. The genotype of a blue pup produced by a fawn parent can be only blue #6/Bbdd.

As for the rest of what I was driving at, I reconsidered it and decided it was probably too pedantic and hypothetical to be of interest. So, never mind!:D

Newborn fawn puppies, once dry are about the color of a cardboard box. Those puppies are blue.

She doesn't even know the correct color of her puppies? Wow, just what our breed needs :(

I don't think I'd be so quick to make that judgement. If you've never seen a newborn fawn or blue Dobe puppy and you don't have a pretty clear understanding of how the genetic color heredity of a Dobe works you might not recognize blue from fawn if the litter didn't have at least one of each color.

If you've got both blues and fawns you can tell the difference immediately but if you only have one of the dilute colors and you've never seen it before on a newborn you might not.

I know a breeder who had nearly 30 years experience breeding and who was breeding some pretty nice dogs and who had been mentored by a couple of people who were very knowledgeable. She'd never had a dilute puppy born from any of her breeding. I got a call when the daughter of a dog I owned whelped a litter of red and black puppies and one dilute bitch. The breeder of my dog (who was also pretty knowledgeable couldn't decide if it was blue or fawn) had also never seen a newborn blue or fawn.

They called me and I told them the same thing that I said earlier on this thread--"fawns when dry and newborn are the color of a cardboard box--blues are distinctly blue and usually a light slate color."

It was a blue.

And it was only a fluke that the dilution, which was there in the form of a blue male nearly 10 generations back hadn't popped up before. But if you happen to be breeding your bitches who were carrying the dilution gene to dogs who didn't you can definitely figure you don't have dilution in your lines 'cause you've never seen it.

Now of course, if anyone is all that concerned about the possibility of getting dilute colors can gene test for color and avoid the possibility of dilution entirely.

Interesting ideas. I've always called it "Mousey color vs buffy color." That's how I tell them apart.
I've seen lots of pix of rescued dilute Dobes (from unknown backgrounds) whose color was so washed out it was difficult to tell if they were blues or fawns just from the pix. (Artificial lighting can also mislead one.) I had to see the dog in person and check the color of its eyes, nose and paw pads to be sure.
