A retrospective report of 90 dogs with suspected cane toad (Bufo marinus) toxicity

OBJECTIVE: To report the clinical characteristics of toad toxicity in domestic dogs in Brisbane. DESIGN: A retrospective analysis of clinical cases. PROCEDURE: All cases of toad poisoning which presented to a northern suburbs emergency clinic in Brisbane over a 30-month period beginning in April 1999 were reviewed. RESULTS: A total of 90 canine cases of suspected toad poisoning were reviewed. Small breed dogs accounted for 76% of cases. Jack Russell, Silky, and Fox Terriers were the most represented breeds. Cases were reported year round, with fewest cases over the winter months. The most common clinical signs were increased salivation (78% of cases), and red oral mucous membranes (63% cases). Seizures occurred in 31% of cases. Generally the outcome was excellent with 96% survival.
