I have a Basenji that I adopted at 2 years of age. She was diagnosed with Fanconi at age 9, both through a Venus Blood Gas Test and a DNA test. She will be 13 years old in a few days and has been in very good health. She does follow a protocol prescribed by Dr. Gonto.
Recently however she will not eat in the morning and rejects foods she would normally eat. She appears to be slowing down and spends a lot of time sleeping.
I am not sure if this is related to old age or Fanconi is beginning to take a toll on her. Hope to keep her around for another year or two.
