Have you noticed your pooch's waist line expanding? Is your cat looking skinny? What does this mean? Well, it could be a few things. Weight changes in our pets -- as in us -- are a result of calories eaten and calories burned being out of balance. In some cases, a pet's weight change can be a symptom of a medical issue, so it's important to explore what might be causing a weight gain or loss.
Weight gain First, you need to look at your pet's diet. Like humans, as pets age, their metabolism slows down a bit. Keeping extra weight off is not as easy as it was during their younger years. For an older pet, it is extra important to watch their fat and calorie intake, and make sure your pet receives enough exercise. If it is determined that diet or lack of exercise is not the issue, then the possibility of other health issues should be explored.
In older dogs, weight gain raises flags that suggest illnesses such as hypothyroidism, hyperadrenocorticism (Cushing's disease) or diabetes. In addition to weight gain, look for other symptoms to help your vet make a diagnosis. Increased water intake and urination can indicate Cushing's disease or diabetes in an older dog, while heat-seeking behavior can be another symptom of hypothyroidism. Depending on the symptoms, your veterinarian will suggest tests to determine the cause.
For cats, weight gain is usually associated with too much food, or diabetes. It is rare for cats to develop hypothyroidism or Cushing's disease.
Weight loss Is your pet is losing weight? First, look at diet and make sure the amount of your pet's food intake is correct. If that checks out, then you must consider the possibility of illness or a medical condition. In older cats, a common cause of weight loss is hyperthyroidism, a condition where the body produces too much of the thyroid hormone. Too much thyroid hormone can cause an unhealthy increase in metabolism. Hyperthyroidism is rarely seen in dogs. Unexplained weight loss in a dog or a cat must also alert your veterinarian to check for conditions such as kidney disease, liver disease, gastrointestinal disease, or cancer.
