I have a Soft Coated Wheaten Terrier that is now 1.5 years old. The
fur around her eyes has recently started to change from a wheaten color
to a more reddish one.

This is not color genetics but tears are staining her pale coat. That is
either normal (but ugly), or she might have an eye inflammation. Depends on
the amount of staining.
