  Urate is the third most common component of canine uroliths. Dogs with a genetic mutation or hepatic dysfunction are prone to forming urate uroliths because they excrete more poorly soluble urate as the end product of purine metabolism. Dietary purine restriction has been reported to reduce urinary urate concentrations in dogs, but the amount and types of purine in commercial diets have not been well documented. A previous targeted metabolomics method was modified to measure eleven purine metabolites in commercial dog foods. The method utilized hydrophilic interaction liquid chromatography-high-resolution tandem mass spectrometry with stable isotope-labeled internal standards. The within-day and between-day coefficient of variation of each purine metabolite concentration in quality control dog food samples averaged 6% (range: 4%-13%) and 15% (range: 11%-19%), respectively.
