Cardiovascular diseases occur frequently in dogs, especially in older dogs (> 7 years). This is the case with myxomatous valvular degeneration (mvd), which is an acquired disease whose hallmark is the presence of audible murmurs on auscultation. The aim of this research was to analyze the demographic influence on outcomes of patients with drug treatment and hyponatraemic dvm diets. We worked with 60 patients weighing up to 15 kg, females and males, whole or neutered, between 6-15 years of age who had the disease in stage B and C requiring medication and dietary support. An initial sample was taken of electrolytes (Na, Cl and K), blood count, total protein, urine specific gravity and creatinine, and imaging tests (radiology, echocardiography and electrocar diography) were performed; the animals were subsequently divided into three study groups of 20 patients each who were pharmacologically medicated with enalapril and spironolactone (Cardial®) and each was assigned a different diet (Mixed and concentrated Diet, Hill’s H / d and Hill’s®K / d®). The results showed that patients who were given hyponatremic diets had better clinical behavior and a higher survival rate. Patients whose owners belonged to lower socioeconomic levels also lacked the economic capacity to manage their pets using these diets, which affected the health of the patients, whose mortality rate was very high (90%).

Introduction: the objective of this paper was to find a connection between cystic endometrial hyperplasia (ceh)-pyometra and polycystic ovaries through observation and macroscopic measurements of canine uterus in subjects with pyometra that underwent hysterectomy to solve the problem. Methods: such organs were obtained from two clinics in Bucaramanga. All the found variables were registered in Excel 2003 and analyzed with Epi Info 7, so as to develop an invariable descriptive statistics analysis, a contingency table and a Fisher’s exact test. The pyometra and ceh were correlated with polycystic ovaries (po). Statistically, there was no relation between such variables, (p> 0,05). Results : existence of ceh was 87.10% of the total cases in respect of the polycystic ovaries frequency, since only 32.26% was not found to be statistically related. Literature reports that the etiology of the ceh complex is caused by an increase in estrogenic hormones in the diestrus phase [1] and such hormone imbalance is in turn responsible for the development of polycystic ovaries. Conclusions: it would be thus appropriate to conduct studies with the hormone measurements in canine subjects with pyometra and verify the macroscopic findings of such cases.
