Clinical findings in dogs and cats with lead poisoning.

Abstract

Over an 11-year period, 68 cases of lead poisoning were diagnosed in dogs and three in cats, accounting for 58.6% and 21.4% of the accidental poisonings in dogs and cats, respectively, presented at the Small Animal Clinic, University of Queensland. Of the dogs, 94% showed alimentary tract involvement and 67.6% central nervous system signs. Blood lead concentrations above 0.3 ppm were considered to indicate toxicity when associated with alimentary tract or central nervous system abnormalities. The percutaneous absorption of lead in dogs is proposed as a factor for intoxication.
