As most know, Athena is a blue Bully. As she's gotten older, 6 months last week, we've noticed her coat has reddish brown in it. She still looks very much predominantly blue, but it is very noticeable, especially in sunlight. Is this what I've read would be considered a blue -brindle? Is it nothing and just normal with blues? Don't care either way other than my continuing quest to educate myself on this great dog. Thanks in advance. I'd post close up pics but the wife's camera is broke. And SLR's sure ain't cheap to fix!!!
