Objective: Assess markers for pancreatic function and gastrointestinal malabsorption in African painted dogs (Lycaon pictus), including canine trypsin-like immunoreactivity (cTLI), canine pancreatic lipase immunoreactivity (cPLI), cobalamin, and folate at one North American facility.
Animals: 15 healthy African painted dogs held at one institution were sampled during routine health examinations.
Methods: Blood was collected at routine health examinations, and serum was separated and stored until testing. Serum was analyzed for cTLI, cPLI, cobalamin, and folate. The results were evaluated for correlation to sex, age, and storage time of samples.
Results: All individuals had cTLI and folate levels below normal reference ranges for domestic dogs (< 5.0 µg/L and < 7.7 µg/L, respectively). Cobalamin values were within or above reported domestic dog ranges, and cPLI values were within range as well. No analytes were significantly influenced by sex or time in storage, while cTLI was positively correlated with age.
Clinical relevance: cTLI and folate did not fall within normal domestic canid reference ranges in this population of healthy African painted dogs. Clinical interpretation of these values based on domestic canid recommendations would indicate clinical disease, which was not apparent in this population. Analytes for pancreatic function and malabsorption or gastrointestinal indicators, including cTLI, cPLI, and folate, in African painted dogs should be interpreted with caution when using domestic dog references ranges.
