You must keep your pet quiet and prevent him her from jumping, or biting at the sutures. Your veterinarian will discuss postoperative care of the incision, including when the sutures will be removed. Spaying and neutering often are blamed for causing overweight in dogs. An unaltered dog allowed to roam far from home looking for an opportunity to breed is coincidentally getting more exercise than one that is not, but getting any pet enough exercise requires human participation. Overweight carries the same disadvantages and dangers for the dog as for the human.
Obesity can cause impairment of heart, respiratory and digestive functions.
If the dog has orthopedic defects, excess weight on the joints can aggravate the condition. Skin irritations can develop where rolls of fat rub one another, and the dog's immune system is less resistance to bacterial and viral infections. The obese dog has a far greater potential for health problems than the ideal weight dog. Wolves, the dog's ancestor, hunt for their food and eat enough to meet their needs. Domesticated dogs are no longer required to exert great energy to feed themselves.
