A two‐year‐old male Barsoi dog was presented after a two‐week period of muscle twitching and convulsions during exercise, which worsened to a state of tetraparesis and coma. Removal of a gastric foreign body, containing aluminium, resolved the presenting signs. Parallel with this clinical recovery the elevated serum levels of aluminium decreased to values of two normal control dogs, suggesting that the neurological signs were due to A1 intoxication.
