title: Ivermectin toxicosis in a dog.
abstract: A 5-year-old male Doberman Pinscher was examined after ingesting an equine paste dewormer containing approximately 115 mg of ivermectin. Clinical signs consisted of profound hypothermia, mild dehydration, dilated unresponsive pupils, localized muscle group fasciculations around the face and hind limbs, and no response to any external stimuli. Twelve days after parenteral administration of isotonic fluids and IV administration of dexamethasone and dimethyl sulfoxide, the dog returned to a clinically normal neurologic state. Ivermectin toxicosis has been reported frequently in Collies; however, other breeds may have idiosyncratic reactions to low doses. Patients with severe toxicosis should eventually recover completely if given appropriate intensive care.
