There are a number of signs for Fanconi Syndrome; excessive water drinking, frequent urination and a general loss of condition are all signs of this condition. Prior to the DNA (linkage marker) test being made available most breeders and owners tested their dog’s urine once a month. This simple test using diabetic (glucose) strips will indicate if the dog is spilling sugar into the urine. If the strip test proved to be positive then further professional examination of blood glucose spillage should be undertaken; unlike diabetes sugar in the blood is low or normal with Fanconi Syndrome. Some vets have misdiagnosed Fanconi Syndrome as diabetes and offered diabetes treatment, unfortunately, generally with disastrous results.
