Metabolic Parameters in Obese Dogs Undergoing to the Diet with Calorie Restriction

Currently, canine obesity is a worldwide problem and is based on the excessive deposit of fat tissue, which plays an important role as a store of energy and endocrine organ. This study aimed to compare the values of systolic blood pressure, serum chemistry profile and glucose metabolism in eight obese dogs without endocrine diseases before and after 16 weeks of a weight loss program. A statistical difference was noticed in the serum levels of alkaline phosphatase, gamma glutamyl transferase, glucose, cholesterol and insulin, before and after the program. Besides, there was a statistical difference between the moments in systolic blood pressure, body weight and body condition scale. Therefore, it was concluded that the use of a diet rich in fiber and protein is suitable for performing weight loss and obese dogs undergoing a weight loss program presented a significant reduction in blood pressure, blood glucose, insulin, blood cholesterol, serum activity of alkaline phosphatase and gamma glutamyl transferase.

Gastric Leiomyosarcoma Associated with Hypoglycemia in Dog—A Case Report

Neoplasms of the digestive system are uncommon in dogs, and may be of epithelial, neuroendocrine, hematopoietic and mesenchymal origin. The leiomyosarcoma is a tumor of mesenchymal origin of smooth, malignant, slow-growing muscles. Paraneoplastic syndromes can affect different systems, being the most commonly found: hypercalcemia, hypoglycemia, cachexia and anemia. There are rare cases of mesenchymal tumors of the gastrointestinal tract in dogs that result in hypoglycaemia with clinical signs. The objective of this study is to report a case of gastric leiomyosarcoma associated with clinical hypoglycemia. The patient had neurological signs such as ataxia and seizures associated with hypoglycemia, which did not recur after surgical excision of the tumor. The definitive diagnosis was based on the histopathological and immunohistochemical examination of the tumor.

Blood Pressure Evaluation in Dogs by the Method Doppler and Oscillometric

Blood pressure is currently a very important tool for clinical and veterinary surgery, especially in monitoring patients under anesthesia and in emergency situations. Hypertension can cause a number of changes in the body of dogs and cats, especially those who are middle-aged and elderly. In veterinary medicine, the blood pressure can be measured non-invasively and invasively. The non-invasive, or indirect technique, is frequently used during routine examinations since it presents convenience as it can be carried out quickly, although it is less accurate. For this research 245 dogs were selected, with one to ten years of age, of both sexes, castrated and uncastrated of different breeds and body scores. The dogs were weighed and had the body condition score determined using the system of 9 points, being categorized into: Control group, overweight group or obese group. Systolic blood pressure was obtained by non-invasive method using the Doppler flowmeter and the oscillometric method. 48 animals were excluded due to the high variability of values, with systolic blood pressure greater than 160 mm?Hg, as well as uncooperative and/or aggressive patients. There was agreement between both methods in 197 dogs conscious and asymptomatic and, therefore, this study showed that oscillometric method can be used in normotensive patients as the study was conducted in patients of different sizes, breeds, ages, body scores and sexual status.
