Dogs and cats that exceed the standard weight 10% ~ 15% are considered obese. In developed countries, obesity is the most common nutritional disease in dogs, cats and people, and the incidence rate is on the rise. With the continuous growth of people's pets, pet obesity has gradually emerged. The easiest way to identify whether a pet is obese is: when touching the ribs with your hands, if there is no layering, it means that you are obviously obese. Obese dogs and cats have other physiological characteristics: when they look down at animals or swing from side to side, their bellies protrude; Swelling of fat areas on both sides of abdomen and ribs; Walking from side to side is not a normal gait. Obesity often brings many unexpected hazards to pets: First, joint or bone movement disorders. More than 24% of obese dogs suffer from severe joint syndrome, including arthritis and disc herniation. In Beijing, there are more and more dogs with disc herniation due to obesity. The treatment of this disease is very difficult and often recurs. Second, it is difficult to breathe. It is more obvious when you exercise. This is due to obesity caused by excessive fat, which thickens the chest wall and increases the body's oxygen demand. The author once saw a bulldog with cyanosis after exercise due to obesity, which was very pitiful. Thirdly, congestive heart disease is caused by cardiac overload, which can be clearly verified in anatomical animals with sudden clinical death. Fourth, obesity can lead to fatty liver and gallbladder disease. The author once treated an old and obese Bucky. After sudden death, it was found that liver fat deposition was serious and liver ruptured. Fifth, obesity reduces reproductive capacity, which is very obvious in individual breeding purebred dogs. Excessive nutrition and lack of exercise lead to fat accumulation in the body, which greatly reduces the estrus and pregnancy ability of bitches. Sixth, the rate of dystocia has increased. Obese animals are prone to dystocia even if they are pregnant. According to the statistics of caesarean section in our hospital, the probability of dystocia in obese dogs is above 80%; Pet obesity makes it difficult for veterinarians to master the dose of * * * during surgery; Due to excessive subcutaneous fat, the wound healing of animals after operation is slow. Seventh, obesity can also be accompanied by some endocrine diseases, such as diabetes. Eighth, obese animals are more prone to skin diseases. For clinical veterinarians, dermatosis is the most common and headache disease. Ninth, obesity makes clinical diagnosis more difficult, such as auscultation and indwelling needle, which affects the diagnosis of diseases and may even lead to treatment errors. You see, how big is the hidden danger of animal obesity. As a veterinarian, I remind you that for the sake of animal health, let it lose weight. There are several ways to lose weight: 1. The calorie intake of exercise to lose weight must be lower than the calorie consumption. In order to achieve the goal of losing weight, the most effective way to consume a lot of calories is exercise. 2. Energy control is to feed animals with low-fat and high-fiber food. Many pet shops and clinics have special pet food, and at the same time, they should reduce the ration and feed them many times. This can increase the loss of heat, thus reducing the synthesis of fat. 3. Hunger to lose weight For obese dogs, hunger has no side effects and is the simplest method that can be adopted. The above three methods of losing weight can be done by every animal owner. Fat and thin animals are not only beautiful in appearance, but also can prolong life.
