Thank you for all your replies. I truely appreciate learning so much about everyone on this board. Unfortunately, I don't know what the parents of my pup is due to being a rescue dog. He was found in a garbage bin, then a shelter, then a rescue, then in my life!
@tanza:
I did send you an email, but it is good to repeat here, I think. The protocol for treatment of Fanconi, information about Fanconi, information about strip testing can be found both at www.basenji.org and www.basenjihealth.org
Thank you so much for the info to pass on.
