The red wheaten is a different color from the mahogany color. When you see the colors "in real life" it is easy to see the difference.
Another thing I have noticed the last year or so; many ridgebacks have the dark red, but their masks (in the face) have become dilluted and brownish, not very attractive. I prefer a mask that is black, and that is defined. Doesn't matter if it's just a little black around the eyes, or a full "burglar" mask.
So I have been wondering if this undefined, dark brownish mask is a result of breeding for darker red?
A friend of mine owns a light wheaten ridgeback. The dog is a good representant for her breed, but she could have had a better head. Whenever the dog is shown for judges from SA, or judges that are breeders/specialists of ridgebacks, it always gets compliments for the "true and original ridgeback color" and after the judging is done, is called forward so that the judge can tell everybody that is present: this is the original color, take care of it.
The light wheaten is actually a beautiful color, and I think my next ridgeback will be one of those.
Jem, just make sure that the parents are healthy and good representants for their breed. Also check out if the breeder is ok, after all, the puppy is spending 8 of it's most important weeks of life with the breeder. If there are lines you want to buy from, that produces a certain trait or feature, that is ok, as long as it is within standard. Dark red is, mahogany is not. Good luck with your search.
