The acquired form of Fanconi syndrome is seldom identified in dogs; those cases that have been reported have been secondary to hepatic copper toxicosis, primary hypoparathyroidism, ingestion of chicken jerky treats, exposure to ethylene glycol, or gentamicin toxicity. However, to the best of our knowledge, there have been no reports of acquired Fanconi syndrome secondary to Babesia infection or ingestion of cosmetics in dogs. We here report on two dogs presented with a history of marked polyuria, polydipsia, and lethargy. Laboratory examinations showed glucosuria with normoglycaemia and severe urinary loss of amino acids. One dog was infected with Babesia gibsoni and the other dog had a history of cosmetics ingestion. The first dog received treatment for Babesia infection and the second dog received aggressive care to correct metabolic acidosis, electrolyte imbalances, and other add-on deficiencies. In both dogs, the Fanconi syndrome was successfully managed following the treatment for the underlying causes. In conclusion, both Babesia infection and cosmetics ingestion should be considered as a possible aetiology for transient acquired Fanconi syndrome in canine patients.
