IRON TOXICITY IN DOGS
 
Description    Dogs can develop iron toxicity, often due to ingestion of iron supplements. There can be hemorrhagic gastroenteritis, hepatic failure, acidosis, coagulation defects, cardiovascular collapse, and occasionally death. Signs can occur in 3 phases: up to 6 hours of gastrointestinal signs; 6-24 hours of apparent clinical recovery; and (in severely-poisoned dogs) a third stage of severe multisystemic signs followed by gastrointestinal scarring and stricture formation.
