Thanks to advances in veterinary medicine, pets are living longer than ever before. However with this increased lifespan comes an increase in the types of ailments that can afflict senior pets. As pets reach the golden years, there are a variety of conditions and diseases that they can face, including weight and mobility changes; osteoarthritis; kidney, heart, and liver disease; tumors and cancers; hormone disorders such as diabetes and thyroid imbalance; and many others. Just as the health care needs of humans change as we age, the same applies to pets. It’s critical for pet owners to work closely with their veterinarian to devise a health plan that is best for their senior pet.
When Does “Senior” Start? So when is a pet considered a senior? Generally, smaller breeds of dogs live longer than larger breeds, and cats live longer than dogs. Beyond that, the life span will vary with each individual, and you determine what stage of life your furry friend is in. Keep in mind that some small dog breeds may be considered senior at 10-13 years, while giant breeds are classified as seniors at ages as young as five.
Senior Health Exams Scheduling regular veterinary examinations is one of the most important steps pet owners can take to keep their pets healthy. When dogs and cats enter the senior years, these health examinations are more important than ever. Senior care, which starts with the regular veterinary exam, is needed to catch and delay the onset or progress of disease and for the early detection of problems such as organ failure and osteoarthritis. We recommend that healthy senior dogs and cats visit the veterinarian every six months for a complete exam and laboratory testing. Keep in mind that every year for a dog or cat is equivalent to 5–7 human years. Client education and laboratory testing are also key components of the senior exam.
Laboratory Testing Veterinarians depend on laboratory results to help them understand the status of your pet’s health.
Complete Blood Count. This common test measures the number of red blood cells, white blood cells and platelets in a given sample of blood. The numbers and types of these cells give the veterinarian information needed to help diagnose anemia, infections and leukemia. A complete blood count also helps your veterinarian monitor your pet’s response to some treatments. When your pet is healthy, laboratory tests provide a means to determine your pet’s “baseline” values. When your pet is sick, the veterinarian can more easily determine whether or not your pet’s lab values are abnormal by comparing the baseline values to the current values. Subtle changes in these laboratory test results, even in the outwardly healthy animal, may signal the presence of an underlying disease. We recommends that dogs and cats at middle age undergo laboratory tests at least annually. During the senior years, laboratory tests are recommended every six months for healthy dogs and cats. At a minimum, the following tests are recommended:
Urinalysis Laboratory. Analysis of urine is a tool used to detect the presence of one or more specific substances that normally do not appear in urine, such as protein, sugar, white blood cells or blood. A measurement of the dilution or concentration of urine is also helpful in diagnosing diseases. Urinalysis can assist the veterinarian in the diagnosis of urinary-tract infections, diabetes, dehydration, kidney problems and many other conditions.
Blood-Chemistry Panel. Blood chemistry panels measure electrolytes, enzymes and chemical elements such as calcium and phosphorous. This information helps your veterinarian determine how various organs, such as the kidneys, pancreas, and liver, are currently functioning. The results of these tests help your veterinarian formulate an accurate diagnosis, prescribe proper therapy, and monitor the response to treatment. Further testing may be recommended based on the results of these tests.
Parasite Evaluation. Microscopic examination of your pet’s feces can provide information about many different kinds of diseases, such as difficulties with digestion, internal bleeding, and disorders of the pancreas. Most importantly, though, this test confirms the presence of intestinal parasites, such as roundworm, hookworm, whipworm, tapeworm and giardia.
Thyroid Screen. For cats, an additional routine blood test, Total T4 is recommended in order to check for hyperthyroidism, a common ailment in senior cats. For dogs, a Total T4 can help screen for hypothyroidism. In both cases if the Total T4 is abnormal (too high or too low) then additional thyroid function testing will be necessary to determine the best treatment.
Additionally, depending on your individual pet’s condition and other factors, other tests and assessments might be recommended. These include heartworm tests; feline leukemia/feline immunodeficiency virus test in cats; blood pressure evaluation; urine protein evaluation; cultures; imaging such as x-rays, ultrasound, and echocardiography; electrocardiography, and special ophthalmic evaluations, among others. Additional tests become especially important in evaluating senior pets that show signs of sickness or are being prepared for anesthesia and surgery.
Surgery for the Older Pet In the event your veterinarian is considering surgery or any other procedure in which anesthesia is needed, special considerations are taken to help ensure the safety of your senior pet. We require all dogs and cats undergo the laboratory testing mentioned above, ideally within two weeks of any anesthetized procedure. A blood pressure evaluation and additional tests might also be recommended, depending on your individual pet. These screening tools can provide critical information to the health care team to help determine the proper anesthesia and drug protocol for your pet, as well as make you aware of any special risk factors that might be encountered.
The Effects of Age Age is not a disease, but there are disease processes that occur more commonly with aging.
Sensory Changes With the senior years comes a general “slowing down” in pets. As their major senses (sight, hearing, taste, touch, and smell) dull, you may find that your pet has a slower response to general external stimuli. This loss of sensory perception often is a slow, progressive process, and it may even escape your notice. The best remedy for gradual sensory reduction is to keep your pet active—playing and training are excellent ways to keep their senses sharp. Pets may also be affected mentally as they age. Just as aging humans begin to forget things and are more susceptible to mental conditions, your aging animals may also begin to confront age-related cognitive and behavior changes. Most of these changes are rather subtle and can be addressed in a proactive manner. Regular senior health exams can help catch and treat these problems before they control your pet’s life.
Physical Changes The physical changes your pets experience are generally easier to spot than the sensory changes. As the body wears out, its ability to respond to infection is reduced, and the healing process takes longer. Therefore, it is crucial to consult a veterinarian if you notice a significant change in behavior or the physical condition of your pet. Many of the signs indicating that animals are approaching senior citizenship are the same for both cats and dogs, but they can indicate a variety of different problems (see Signs of a Problem, below). A very common and frustrating problem for aging pets is inappropriate elimination. The kidneys are one of the most common organ systems to wear out on a cat or dog, and as hormone imbalance affects the function of the kidneys, your once well-behaved pet may have trouble controlling his bathroom habits. If you are away all day, he may simply not be able to hold it any longer, or urine may dribble out while he sleeps at night. In addition, excessive urination or incontinence may be indicative of diabetes or kidney failure, both of which are treatable if caught early enough.
Nutrition Dogs and cats should be fed diets specifically designed for their breed, age, and activity level. These factors are also known as physiological state. Dogs and cats should be fed according to their specific nutritional needs. Cats are not small dogs and have very different nutritional requirements than dogs, whereas dogs have nutritional needs more similar to people than cats. As your pet ages from birth into adolescence, adulthood, senior and finally becomes geriatric, their nutritional requirements change. These changing nutritional needs have been called “life stage nutrition” and are the logic behind diets designed for growth, maintenance, reproduction, and the geriatric stage of a pet’s life. Life stage nutrition is feeding diets designed to meet the optimal nutritional requirements of animals at different ages or physiological states. Not all pet food manufacturers ascribed to the nutritional principle of lifestages and therefore have one nutrient profile that fits “all stages”. These products carry the AAFCO statement “for all lifestages”. We do not believe this is the best way to feed pets just as one shoe size does not fit all people. Many older pets benefit from specially formulated food that is designed with older bodies in mind. Obesity in pets is often the result of reduced exercise and overfeeding and is a risk factor for problems such as heart disease. Because older pets often have different nutritional requirements, these special foods can help keep your pet’s weight under control and reduce consumption of nutrients that are risk factors for the development of diseases, as well as organ- or age-related changes.
Exercise Exercise is yet another aspect of preventive geriatric care for your pets. You should definitely keep them going as they get older—if they are cooped up or kept lying down, their bodies will deteriorate much more quickly. You may want to ease up a bit on the exercise with an arthritic or debilitated cat or dog. Otherwise, you should keep them as active—mentally and physically—as possible in order to keep them sharp. Controlled leash walking on flat surfaces and gentle inclines is the best way to help maintain fitness and lean muscle mass in aging animals. Help them avoid repetitive jumping or erratic stops and starts on uneven terrain where they are more likely to suffer a soft tissue injury. Sustained leash walking, varying the pace at different walking speeds throughout a 20 minute walk can help burn more fat and build muscle without putting damaging stress on joints and connective tissues.
Pain Management Pets experience pain just like humans do, and identifying, preventing, and minimizing pain in all senior dogs and cats is important. The different types of pain include acute pain, which comes on suddenly as a result of an injury, surgery, or an infection, and chronic pain, which is long lasting and usually develops slowly (such as arthritis). You can play a key role in monitoring your pet to determine whether he suffers from pain. To help ensure your pet lives comfortably during the senior life stage, it’s critical to tailor a senior wellness plan that is best for your dog or cat. Be sure to monitor behavior and physical conditions and report anything unusual to your veterinarian, who can help your pet head into the twilight years with ease.
