Looking After Your Senior Dog's Food Needs

Dogs are usually considered to be old when they are halfway through their expected lifespan. The lifespan of dogs varies depending on the breed. Smaller dogs age relatively slowly when compared to larger dogs. Small dogs can live anywhere between 15 and 20 years, while large dogs live for anywhere between 12 and 15 years. Let's take a look at how you can modify your dog's diet to match its needs once it starts aging.

What should their diet include?

As dogs age, their metabolism rate also slows down. They may easily gain weight and grow obese as a result of this. Then again, your dog's physical activity may be greatly reduced because of joint pain and other ailments. This could further worsen conditions like obesity. It helps to include low-calorie food in your dog's diet. Along with low-calorie food, it's also important to include more fiber in the diet. You can look for senior dog-specific diets and products such as Wellness Super5mix Just For Seniors Dry Dog Food that meets the nutritional requirements. Senior dogs also tend to have a lower appetite than they did in their younger days. If your senior dog is not eating, you have to consult a vet to see if it is due to loss of appetite or some underlying health issue. If it is the former, you can try using flavor enhancers to improve its taste, or appetite stimulants, if needed. Make sure that your senior dog gets an adequate amount of water, as its ability to retain water balance reduces as it grows older.

Health conditions and supplements

If your senior dog is suffering from health conditions, then you want to consult a vet to decide on an appropriate diet. For instance, diabetes happens to be a common medical condition in older dogs, and you will require a special diet where the food is absorbed slowly in case your dog has diabetes so that the blood sugar levels do not instantly shoot up. Similarly, a dog with a heart condition will require a diet that has low sodium and calories. Supplements may be a good addition to your dog's diet, and you should consult the same with your vet before you take a call. Many dog owners supplement their pet's diet with vitamins as they age. Others use supplements like chondroitin and glucosamine to treat joint problems. While supplements do help, it's also important to support them with the right lifestyle habits. For instance, if your senior dog has arthritis, it helps to keep its weight in check, instead of just supplementing its diet with glucosamine. While we're on the subject of supplements, it is important to note that you should use veterinary supplement formulations and not what is prescribed to humans.

Choosing a Dog Food for Your Senior Dog

Is your dog getting a little gray around the muzzle? Is their body shape starting to look a little different?

If yes, these are signs that your dog is beginning to age. “Senior,” however, is a different age number for each breed because larger dogs mature before their smaller counterparts. As a general rule, small and toy breed dogs tend to become seniors at around 10-12 years of age, while medium size dogs (20-50 lbs.) become seniors around 8-10 years of age, and large and giant breed dogs hit their golden years around 6-8 years.

“Although we tend to put a timeline on these breeds, there is nothing special about the years, it’s more about seeing changes in your dog,” says Dr. Joseph Wakshlag, Clinical Nutritionist from the Cornell University Hospital for Animals. “There are physiological changes such as the eyes starting to look a little cloudy, a decreased activity which can represent mild osteoarthritis, and body condition changes." Some older dogs lose muscle mass and gain fat, while others just lose muscle mass and start to become thin. All dogs start to lose muscle mass to some degree; this is a condition known as sarcopenia and is a universal indicator of aging.

The Key to Good Senior Nutrition

Nutritionally, there are a few guidelines to use in keeping your senior happy and healthy. The most important factor is weight change: is your dog gaining or losing weight? Many pet owners will instinctively reach for senior food when their older dog starts to gain weight. But did you know that most senior foods cut protein down from the 22-32% average to a meager 18-22% of protein? Unless your senior dog has kidney or liver disease, their body will crave the missing protein. 

The Pooch that gets a Pooch

Dr. Wakshlag recommends a different approach for pooches with a pooch: “There is no need to protein restrict the healthy older dog. Maintaining lean mass is an important concept. I would rather see the pet owner reach for a lower fat food.” A gram of fat has over twice the caloric content of a gram of carbohydrates or proteins. This means that lower-fat foods will help keep your senior’s tummy full without the added pudge. Dry food with less than 12% fat or wet food with less than 3% is the ideal marker to keep the calorie count down.

The Skinny Seniors

Or maybe your senior has been losing weight? Maybe your dog just seems pickier with age, or maybe they just won’t eat as much of the same food. In this case, Dr. Wakshlag recommends feeding them the way you did when they were a puppy. “There are some dogs that have always been picky eaters and tend to lose muscle mass as they age. These dogs actually need higher protein and fat foods like the type of food you feed puppies or performance dogs.” As a general rule, dry foods with 24-32% protein and 16-20% fat or wet foods with a minimum of 8% protein and 4% fat will boost your skinny senior’s energy.

The Importance of Antioxidants

No matter your senior’s size, you may want to consider an antioxidant fortified food, too. Did you know that antioxidants can help combat canine cognitive dysfunction? This disease, similar to Alzheimer’s for dogs, is fairly common among senior dogs. Dr. Wakshlag explains, "A number of studies in the early 2000s showed that a specific blend of antioxidants actually helped dogs with cognitive dysfunction as they age. This was fairly revolutionary, and we don’t know if the antioxidants in the food the owner is choosing are the important ones, but the traditional ones like vitamin E, carotenoids, omega-3 fatty acids, and vegetable-based antioxidants in small amounts supplemented to food surely will not be harmful, and have the potential to help.” 

There is no “one size fits all” nutrition plan to keep your senior dog healthy but with the right tips and some direction from your vet, the right food can help keep that tail wagging just like it has been since your senior dog was a pup.
