I suppose it could be many things but I think it's genetic. I have a brother and sister from the same line and they both showed a reddish tint at about 6 months that lasted until about a year or so. It wasn't that pronounced but could easily be seen, especially in the sunlight. After that, they both showed a beautiful steel blue color. The sister is spayed (she's only 3 pounds) but the brother has sired pups and they did the same thing. |
