•Diet. Researchers are still exploring what diet is best for dogs with diabetes. Most veterinarians recommend a diet low in fat and high in fiber. Fiber slows the entrance of glucose into the blood and may satisfy your dog’s appetite sooner, so she eats less and loses weight. Your veterinarian may recommend a prescription dog food designed for dogs with diabetes, or a homemade diet developed by a veterinary nutritionist. Some dogs may refuse to eat special diets; in that event, careful choices should be made when selecting a regular dog food. The one food Dr. Schall absolutely advises against for diabetic dogs is the semi-moist type that comes in packets. “They generally contain more refined carbohydrates than other dog foods,” he says.
•Exercise. Exercise not only may help reduce your dog’s weight, it also lowers blood glucose levels. Your dog should exercise every day for about the same length of time at about the same exertion level. Consistency is important—an unusually long or vigorous exercise session can cause blood glucose levels to drop dangerously low.
•Weight loss. If a dog is overweight, shedding some pounds can make the cells more sensitive to insulin, which means that glucose uptake is easier.
•Spaying. Spaying prevents female dogs from going through diestrus.
Day to Day With Your Diabetic Dog
Keeping a logbook can help you monitor your diabetic dog’s progress. Every day, record blood glucose test results; any ketone test results; changes in your dog’s appetite, weight, appearance, water intake, urination frequency or mood; and any treatment changes your veterinarian makes. A simple notebook, calendar or computer spreadsheet works well.
Among the things to watch for on a day-to-day basis are hyperglycemia, when blood glucose levels rise above the top end of the recommended normal level (ask your vet what this is for your dog; since perfect control isn’t always attainable with current methods, vets generally try to keep most dogs below 200 mg/dl), and hypoglycemia, when the level drops to 60 mg/dl or less.
Hyperglycemia can lead to ketoacidosis (harmful levels of ketones in the blood), which qualifies as an emergency, and you should call your vet right away. Symptoms include drinking lots of water, urinating frequently or copiously, loss of appetite, weakness, vomiting, lethargy, ketones in the urine, or—in the most serious situation—coma. Test strips are available to detect ketones in your dog’s urine, and you should report the presence of ketones to your veterinarian immediately, even if your dog has no other symptoms.
In hypoglycemia, a range of symptoms may be present, including restlessness, lethargy, confusion, weakness, wobbliness, lack of coordination, shivering, sweaty paws, seizures or coma. Test your dog’s blood glucose level if these symptoms appear. If it is below the recommended level, rub maple syrup, Karo syrup or tube cake frosting—high-sugar foods that are quickly absorbed into the bloodstream—on your dog’s gums and the inside of her cheek, then call your vet to report the episode and get further instructions.
Modern medicine has made caring for a diabetic dog quite doable and certainly worthwhile. Although daily care can seem burdensome at first, once you get used to it, it becomes a routine part of the day, like feeding her or taking her for walks. Owners do not need to worry that shots and blood tests will take over their lives. Nor do they need to fear that their dog will not be happy. According to Dr. Schall, almost all diabetic dogs can be treated at home and can enjoy a good life. A diagnosis of diabetes offers a challenge, but it’s a challenge that can be successfully met.
