Thyrotoxicosis in a dog induced by the consumption of feces from a levothyroxine-supplemented housemate

摘要

A 9-year-old golden retriever dog was evaluated for polyuria, polydipsia, weight loss, and elevated serum thyroxine. Targeted questioning revealed that the dog was coprophagic and routinely ingested the feces of a dog that was treated with twice-dailylevothyroxine. Clinical signs resolved and serum thyroxine decreased to normal levels in the affected dog with prevention of coprophagy.
