Abstract

The role of the renin-angiotensin aldosterone system in the genesis of hypertension between nonhunting dogs and hunting dogs of various breeds was comparatively studied in the city of Tuzla (Bosnia and Herzegovina). Sixty dogs were divided into four subgroups based on different age categories. Hypertension was recorded in 21 dogs or in 35% of examined dogs. Fourteen dogs had mild (23.3%), 5 dogs had moderate (8.3%), and 2 dogs had severe hypertension (3.3%). The most cases of hypertension (n = 9) were recorded in hunting dogs aged from 9 to 12 years. In subgroups of nonhunting and hunting dogs aged from 1 to 3 years, a high correlation was recorded between systolic and diastolic pressures (P < 0.0001). A certain degree of correlation was recorded between systolic pressure and renin (P = 0.037) and between heart rate and renin (P = 0.024). In subgroups of nonhunting and hunting dogs aged from 9 to 12 years, a high correlation was recorded between systolic and diastolic pressures (P = 0.006) and between diastolic pressure and heart rate (P = 0.002). A certain degree of correlation existed between systolic pressure and heart rate (P = 0.041), systolic pressure and aldosterone (P = 0.035), and heart rate and renin (P = 0.038). Increased values of renin were mostly recorded in dogs with hypertension. This research indicates the importance of routine blood pressure measurement during every examination, which can thus serve as a screening for undertaking further steps in processing the patient.
