I'm not sure what you mean by a base color.

In Pembrokes red is dominate to everything else.

Tri is a double recessive. Red headed tri is domiant to Black headed tri.

Sable is a bit of an unknown still. The jury's out as to if it's a color or a pattern. Seems to be linked to the tri genes. You can have full sables (probably carry black headed tri) or you can have red headed sables (carry red headed tri). Then again you can have sableing on the head an no where else, and we're not sure what that means.

Maybe Debbie can explain Cardigans a bit.

Cardigans have two base colors, red and black. All the other "colors" seen are from color patterns and modifiers on them. Like in Pembrokes, red is dominant to black and there are no bi-blacks in either breed. Sable, what Peggy said, except there has been some speculation that it may be both a color and a color pattern. For a good reference on Cardigan colors go to:

Cardigans have a bunch of modifiers. so there can be a real rainbow of colors that can appear in them. Pembrokes, there are bluies (not the same as merle) and agouti that I know of.

THanks for the info. I was trying to see if my pem corgi is a sable or a very dark read. She is only 11 weeks so has not yet shead out so it is hard to know. I want to get her paperwork in so I wanted to find out the order of inharadence so I could figure it out.

As long was the Pems are the same as the cardigens that site helped me figure it out.

Thanks again,

Heidi

Well, don't decide from what I told you. Most Pem puppies look like they'll be sables as puppies. They usualy aren't and can clear to any shade of red.

Do you have a picture you could send me? Send it to taflarpwc@yahoo.com

I highly doubt she is a sable as it is supost to be a domint midifier so one of her parents would have to carry it and both are very very dark red and it looks like she will be too with some light red mixed in on the head.

Here is a picture of her.

Here is anouther picture of her that shows her back a bit better and her color.

Either or both of her parents could carry the sable and she still might not get that gene. She might have some sable on her back as an adult. That is hard to tell at this point.

She's a red and white. She doesn't have any sable on her head now. Pembrokes change color from the head back, around the eyes first than over the head. She may or may not be a dark red. There's nothing in that picture that says dark red to me but who knows. And the papers don't ask what shade of red. Register her as a red with white markings.

She'll be red, red and white. Most red and white puppies look as if they've rolled in mud so to speak - the brownish cast w/the black interspersed is puppy coat. When she blows her puppy coat, she should be about the color she is on her head now.

She has to be a red of some shad as nither of her parents are sables so she can not be a sable either acourding to the site as it is a dominent gene. So I will register her as a red and hope the judge and show staff does not question it. I know when showing horses they never even ask to see the horse that you are submiting the papers on for the show.

Heidi,

She's a red and white, trust us. Corgis do not have color varieties in the conformation ring, so that is not an issue. And no sable is not necessarily a dominant. Reds, tris, and sable are basically inherited the same in both Cardigans and Pems, but as Peggy and I both mentioned there are still a lot of questions about sable in both breeds. There are many, many red and white Pembrokes that have been registered as sables in error. It is possible to get sable out of two red and white parents. One theory is that black is needed to manifest sable. So one pure for red parent bred to a red carrying for black headed tri could result in sable puppies. But that's an aside and doesn't change that she's a red and white. What color does her breeder say she is?

Chip had the same coloring when he was tiny and he is a red and white. Dale also was the same but his face is starting to turn red already. I really like the red and white. Both boys are registered sables and white. Mom is red and white and dad is a tri.
