Dogs hit maturity around 7 years of age (5 years for larger dogs). It's not uncommon for them to live as long as 15 years. As your pet enters his golden years, his activity level might slow down and common conditions such as arthritis, diabetes, and kidney disease may arise. “It is so more important to monitor the eating habits of older pets,” stresses Tom Carpenter, DVM, president of the American Animal Hospital Association. “Generally, older pets do not need as much protein, sodium, and phosphorus. But your veterinarian needs to address this for your individual pet,” he says, adding that semiannual vet visits are recommended for an older animal.
Some mature dogs are prone to obesity. To test whether your dog is at a healthy weight, move your hands along his sides. If you can feel his ribs (but don't see them), he's doing okay. But if you feel a fat covering, or you visibly notice a rounded abdomen, he might be overweight. Exercise is still important for a senior dog, and if he's gained weight, you want to look for a low-fat weight-control food that contains vitamin-rich fish oils (IAMS™ ProActive Health™ Mature Adult is one good choice).
Other mature pets can become finicky eaters and lose weight as they age. 'Very old pets may actually need a more calorie-dense diet,' Carpenter says. Older dogs can lose their sense of smell and have a harder time chewing their food. To make mature dog food easier to eat, you can top their dry food with room-temperature wet food.
If your dog is gaining or losing a lot of weight, slightly decrease or increase his daily feedings. A sudden change in weight or appetite might be a sign of disease, so you should check with your vet. Water is also essential. 'Older pets are at a higher risk of dehydration,' Carpenter says. Provide a clean bowl with fresh water at all times.
Nutrients like protein, fat, vitamins and minerals are vital to the skin and coat health of dogs. Your dog’s coat is made up almost entirely of protein. If his diet doesn’t contain enough protein quantity and quality, hair might fall out or become dry, weak and brittle. Likewise, his skin is made up of tightly packed flat cells with tough membranes made of proteins and fats. Without proper amounts of these nutrients, the cell membranes weaken, allowing water to escape and bacteria and viruses to enter more easily.
Make sure your dog is getting the following nutrients to keep his coat and skin healthy.
Proteins are found in both animal-based and plant-based ingredients. However, animal-based proteins contain all the essential amino acids dogs need, whereas plant-based proteins might not contain enough of some essential amino acids.
Fats also are found in both animal- and plant-based ingredients and are incorporated into skin cells as fatty acids. In particular, linoleic acid is essential for a dog’s skin and coat health. Without enough linoleic acid, dogs might experience a dull and dry coat, hair loss, greasy skin and increased susceptibility to skin inflammation.
Linoleic acid is found in chicken fat and vegetable oils (such as corn and soybean). IAMS™ research has also found that the fatty acids in vitamin-rich fish oils help promote excellent skin and coat health.
Your dog needs vitamins and minerals for a healthy skin and coat. The best way to provide these nutrients is by feeding a complete and balanced diet full of essential vitamins and minerals, rather than giving him supplements.
Vitamin or Mineral Importance to Skin and Coat Health
Vitamin A Necessary for growth and repair of skin
Vitamin E Protects skin cells from oxidant damage
Vitamin C Helps heal wounds
Biotin Aids in the utilization of protein
Riboflavin (B2) Necessary for fat and protein metabolism
Zinc Necessary for fat and protein metabolism
Copper Involved in tissue, pigment, and protein synthesis
Diet can be a factor when changes in skin and coat condition occur, but the most common causes are season and life stage. As cold weather approaches, most dogs grow a thick coat to help keep heat in and cold air out. As the weather warms up, they shed their thick, heavy coat.
Most puppies are born with soft, fuzzy hair, but as they age, a coarser coat grows. Pregnant or nursing dogs also might experience a change in coat condition or hair loss. And, as with humans, a dog’s hair might thin out and become coarser and white as he reaches his mature years.
