Fanconi Syndrome In Dogs- Overview

Fanconi syndrome is a chronic disease that may affect the kidneys of dogs and cats alike. However it is more likely to appear in dogs. Fanconi syndrome occurs when kidney tubules are unable to adequately absorb electrolytes and nutrients back into the bloodstream. These electrolytes and nutrients are instead released into the urine.

How can you spot Fanconi Syndrome in dogs?

Below are the signs of Fanconi Syndrome in dogs that you should be conscious of:

  • Excessive thirst;
  • Excessive urination;
  • Loss of weight
  • Fatigue
  • Disinterest in diet
  • Vomiting or diarrhoea
  • Seizure

A dog with Fanconi Syndrome does not have any of the signs listed, and other personality differences may also occur. In each breed, the results will be very different.  But if you see any sudden changes or any of the signs described, get your dog to the vet. Early treatment is the secret to full recovery.

Diagnosis of Fanconi Syndrome in Dogs

When a dog gets extra glucose in the urine but not in the blood along with excess amino acids and protein in the urine, it is likely to have Fanconi syndrome. Diagnosis is performed by demonstrating anomalies of renal function, in particular glucosuria, phosphaturia, and amino aciduria. In the case of cystinosis, the slit-lamp examination can show cystine crystals in the cornea. Low blood phosphorus and calcium can be seen during the condition, particularly in young dogs.

How is Fanconi syndrome treated?

There is no way to reverse the abnormal reabsorption of solutes that happens in Fanconi syndrome. The treatment of this condition relies on the nature of the reabsorption defect and must be adjusted to the individual patient. Treatment can include potassium supplements, dietary treatment of kidney disease, and support for normal acid-base balance in the body.

Recovery of Fanconi Syndrome in Dogs

If treatment is given before kidney damage is serious, the dog may have a positive prognosis. Follow-up visits are likely to be required so that the veterinarian can ensure that the medication is effective and make any changes to the treatment based on follow-up and testing. You’ll need to work closely with your veterinarian to ensure the best results for your dog. Although the disease cannot be healed, it can be managed.
