This factor, added to the regularity that it is observed, makes from obesity, nowadays, the most important metabolism disease in dogs, being still able to promote serious health problems, including cardiovascular disorders. For this study, 14 medium-sized neutered mongrel adult female dogs were divided in two groups and submitted to a program of weight gain. Group I, presenting highest percentage of weight gain (average 21.4% above the initial weight, in average) and Group II, with shortest weight gain percentage (15% above the initial weight, in average). Afterwards, both groups were submitted to a obesity correction food program, to reach the initial weight. During the food programs, in the initial phase (T1), obesity phase (T2) and final phase of weight reduction (T3), examinations carried out were: electrocardiographic, radiographic and mensurations of the blood pressure. During the phases T2 and T3, ecodopplercardiographic examinations of all dogs were also performed. At the end of the experimental phase, every variables obtained were statistically evaluated, comparing the groups and the different phases within the same group. The results revealed no significant eletrocardiographic and ecodopplercardiographic alterations, considering up to 21% of increment on body weight; increase of cardiac silhouette on radiographic evaluation during the obesity phase and decrease after the weight loss, and increase of arterial systolic pressure after the weight increment. / A obesidade é uma condição mórbida de ocorrência comum na prática veterinária, estando geralmente associada à redução do tempo e da qualidade de vida dos animais de companhia. Esse fator, unido à regularidade com que é observada, faz da obesidade, atualmente, a forma mais importante de doença do metabolismo em cães, podendo provocar sérios problemas de saúde, dentre eles os distúrbios cardiovasculares. Neste trabalho, 14 cadelas de porte médio, sem raça definida, adultas e castradas foram divididas em dois grupos e submetidas a um programa de ganho de peso. O Grupo I com maior porcentagem de ganho de peso (em média 21,4% acima do peso inicial) e o Grupo II com menor porcentagem de ganho de peso (em média 15% acima do peso inicial). Posteriormente foram submetidas a um programa alimentar de correção da obesidade até atingirem o peso inicial. Durante os programas alimentares, na fase inicial (T1), fase de obesidade (T2) e fase final de redução de peso (T3) foram realizados exames eletrocardiográficos, radiográficos e mensurações da pressão arterial e nas fases T2 e T3 exames ecodopplercardiográficos em todas as cadelas. Ao final da fase experimental, todas as variáveis obtidas foram avaliadas estatisticamente, comparando os grupos e as diferentes fases dentro do mesmo grupo. Os resultados revelaram que não ocorreram alterações eletrocardiográficas e nem ecodopplercardiograficas significativas, considerando incremento de peso corporal de até 21%; aumento significativo da silhueta cardíaca à avaliação radiográfica, na fase de obesidade, e diminuição da mesma após perda de peso e a pressão arterial sistólica dos cães aumenta com o incremento do peso.
