Here are a couple of Schipperke websites:
http://www.schipperkeclub-usa.org/
http://www.schipperke.com/
There is a health category and you can research health problems.
I found it interesting that they have eye and thyroid problems like the Basenji. They can have the PPM which causes the blue tint to the eye. They also have patella problems. There are also diseases specifically to the Schipperke.
If the blue tint does not go away, I would have an eye exam done by an opthalmologist for him. I have a male Basenji who still had the blue tint in one eye as he got older and he has PPM and other eye problems. He is now 4 and the blue color is usually off to one side and can be difficult to see.
I would ask the breeder if the sire and dam of your dog or if any of their dogs in either breed have had PPM and if their breeding dogs have been CERF'd-eye exam.
