Lactic acidosis in a Clumber spaniel.

A three-year-old female Clumber spaniel was examined because of a history of poor exercisetolerance since puppyhood. The dog had the opportunity for free exercise and rest in its yard at home. Usually the symptoms became more evident when the dog was exercised on a lead. During exercise the dog tired quickly, started to pant and salivate, lay down and was unable to rise. After resting the dog always returned to normal condition rather soon, at the latest within an hour. Except for intermittent polydipsia the dog was otherwise healthy and in good clinical condition.
