Active dogs thrive on diets high in fat. To preserve a high-fat dry kibble diet, however, is a challenge. The IAMS research team met that challenge with an effective preservative system used in all our dry dog food products, such as IAMS™ ProActive Health™ Adult MiniChunks.
The preservative system features a special blend of mixed tocopherols. Tocopherols are antioxidants extracted from vegetable oils. There are four major types of tocopherols. Vitamin E, also known as alpha-tocopherol, is commonly used in dog foods, though a specific mixture of the different tocopherols protects against rancidity.
Our preservative system slows the rate of oxidation and allows for an extended shelf life.
Wet foods, such as IAMS™ ProActive Health™ with Chicken and Whole Grain Rice Pate, do not require preservatives because they are preserved by packaging. When the ingredients are mixed and ready for cooking, the mixture is packed into cans, trays or pouches and cooked in a retort. Similar in principle to a pressure cooker, the retort sterilizes and preserves the product.
The cans, trays or pouches are then cooled under conditions that assure product sterility and container integrity.
Thorough shelf-life testing is conducted on all our products. In general, shelf lives for various types of products are:
24 months for wet foods
16 months for dry foods
12 months for biscuits
By using a preservative system in our dry dog food and preservation through packaging in our wet dog food, IAMS makes sure the food your dog eats is well-balanced and nutritionally beneficial.
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.
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.
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.
Continue to use preventive medicines.
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.
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.
