My breeding Australian Labradoodle gets symmetrical “spots” each time she is pregnant. Her coat is cream and apricot and the spots are a darker red. Around the time the pups are born the fur of the spot falls out and the new growth is again the darker red. After the pups are weaned the growing fur changes back to cream where the red is only at the end of the fur. I’ve tried to find information about this and cannot find anything in a google search. Has anyone heard of or seen this before?
