well I looked at your pics and he does look like a tri. if he has reds in him, well just consider it a special trait.
I think that it is great that you are noticing changes in Corky and it is clear that you pay attention to detail. I do the same, and consider myself a bit of an extremist about my boys.
There is no reason to read tense text here and I am sure things read harsher than intended, but can we stay on topic.
Although Fanconi is important to be aware of, I dont think it does anything to Corky's coat of many colors, LOL.:D
Pics would be great!! I have done some searches on this site about colors of basenjis and there are a lot of colors that are not AKC approved and documented. It is pretty interesting stuff…..
Has the weather changed in your area? Do you think it is blowing a coat? My red does that and blows reddishblonde hair which is weird....but it seems to be lighter than his regular coat when summer comes.
