Understanding Common Dog Food Ingredients

Nutrients are divided into subcategories: protein, carbohydrates, fats, vitamins and minerals, and water.

 

 

Protein in Dog Food

Common dog-food protein sources include meat, poultry, fish, and some plant ingredients such as corn gluten and soybean meal.
 

Protein is best known for supplying amino acids, or protein subunits, to build hair, skin, nails, muscles, tendons, ligaments, and cartilage. It also plays a main role in hormone production.
 

Dogs, best fed as carnivores, require essential amino acids, that are not all found in the correct balance in single plant-protein sources such as soybean meal.

 

 

Carbohydrates in Dog Food

Common carbohydrate sources are plants and grains. Carbohydrates, also categorized as starches (sugars) and fibers, provide energy and bulk, respectively.
 

Starches are made up of various types of sugar, such as glucose or fructose. Through digestion, dogs can easily convert sugar into usable energy.
 

Fiber may or may not be fermented or broken down into short-chain fatty acids by bacteria in a dog's intestines. Highly fermentable fiber sources, such as vegetable gums, provide high amounts of short-chain fatty acids. Moderately fermentable fibers, such as beet pulp, provide short-chain fatty acids and bulk for moving waste. Slightly fermentable fibers, such as cellulose, provide mainly bulk for moving waste through the digestive tract and only a few short-chain fatty acids.

 

 

Fats in Dog Food

Fats are found in meats, poultry, fish, and plant oils, such as flax and vegetable oils. Fat, for all of its bad press, fulfills many vital body functions. Animal-cell membranes are made of fat. Fat also helps maintain body temperature, control inflammation, and more. Fat is the primary form of stored energy in the body, providing twice as much energy as carbohydrates or proteins.
 

Fats also provide the important fat subunits, omega-6 and omega-3 fatty acids. Omega-6 fatty acids are essential for skin and coat maintenance and proper membrane structure. Omega-3 fatty acids have been shown to be important in blood clotting and decreasing inflammation.

 

 

Vitamins and Minerals in Dog Food

Vitamins are responsible for promoting bone growth, blood clotting, energy production, and oxidant protection.
 

Vitamins A, D, E, and K require fat for absorption into the body, while vitamins such as the B-complex vitamins and vitamin C need water to be absorbed into the body.
 

Minerals provide skeletal support and aid in nerve transmission and muscle contractions.

    Your Senior Dog’s Health from 7 Years On

    Keeping Your Senior Dog Healthy and Active

    It depends on the breed of dog, but your pet's senior years generally begin at age 7. Louise Murray, DVM, director of the ASPCA's Bergh Memorial Animal Hospital in New York City and author of Vet Confidential (Ballantine, 2008), tells you what you need to know to keep your older dog spry and happy.

     

     

    Senior Dog Health: Preventive Health

    At this stage, Murray recommends taking your dog to the vet twice a year. "So much can happen to an elderly dog," she says. Your veterinarian can take blood annually to test liver and kidney functions. "Discovering problems early is extremely important," she says. Your vet can be on the lookout for conditions that often affect older dogs, such as anemia and arthritis.

     

     

    Senior Dog Health: Urination, Bowel Movements, and Appetite

    Pay attention to what might be subtle changes in your dog's habits: Is she drinking more water or urinating larger amounts? These behaviors might indicate a liver or kidney problem. Have your dog's bowel movements shifted? This could indicate a digestive issue. Diabetes or digestive problems might cause your dog to eat more but still lose weight. Knowing the dog's patterns can help the veterinarian determine a course of treatment.

     

     

    Senior Dog Health: Flea, Tick, and Heartworm Medicines

    Continue to use preventive medicines.

     

     

    Senior Dog Health: Dental Health

    Clean your dog's teeth daily. If she has tartar buildup, you might need to have her teeth professionally cleaned at your vet's office, which requires sedating your pet.

     

     

    Senior Dog Health: Exercise

    Your dog is probably less active, so steady, moderate exercise is best for her now. Don't turn her into a "weekend warrior" who, after lying around on weekdays, accompanies you on a 10-mile hike on Saturdays. This is especially hard on an older dog's joints.

     

     

    Senior Dog Health: Diet

    Your veterinarian might wish to put your dog on a senior diet, such as IAMS™ ProActive Health™ Senior Plus. These formulations contain nutrients specifically geared toward older-dog health.
