Primary haemostasis was evaluated by measurements of bleeding time and platelet count in 26 dogs with leishmaniasis and 10 normal dogs. Bleeding time was significantly (P = 0.02) longer in the infected dogs than in the control group, and in infected dogs with creatinine concentrations > 1.5 mg/dl than in infected dogs with normal creatinine levels. There was a significant linear regression between the concentration of creatinine and bleeding time (P = 0.02) although the coefficient of determination was low (r2 = 0.194). There were no significant differences in platelet counts between the normal and diseased dogs, and there were no significant differences between male and female dogs in either group.
