Physiological condition, rather than chronological age, determines whether a dog is mature. Aging begins when the body's systems start to slow down, when cells deteriorate faster than the body can repair them. Though large breeds tend to age faster than smaller breeds, the mature years generally begin at around 7 years (5 years for large breeds). If you feed your mature dog a diet designed to address the nutritional needs of his age, you can best maintain his overall health and well-being.
As your dog ages, it is important to detect and address with his veterinarian the telltale signs of aging or disease: a dull, dry coat and flaky skin, joint stiffness, energy loss, weight gain, increased water intake, digestive problems, and frequent constipation. These signs, among others, may be caused either by normal wear-and-tear or perhaps by the onset of disease. In any case, detecting and addressing them early may give your dog a greater chance to stay active and healthy.
When and how your dog responds to the aging process has a lot to do with genetics and environment, but nutrition plays an equally important role. The quality of food and its ability to maintain and nourish your dog's cells can help promote a long, healthy life.
As your dog ages and his systems become less efficient, he relies increasingly on the food you provide to make up for his body's shortfalls. According to Michael Hayek, PhD, an IAMS research nutritionist who specializes in geriatric nutrition, 'Aging dogs need the same nutrients as younger dogs; however, the quantity or the way the nutrients are provided may change.'
Congratulations! You're the proud owner of a puppy. It's important to take steps now to ensure great puppy health. Louise Murray, DVM, director of the ASPCA's Bergh Memorial Animal Hospital in New York City and author of Vet Confidential (Ballantine, 2008), offers these pointers for your puppy's first year.
Talk to friends to find a veterinarian you can trust. Within a week of bringing your puppy home, take him for a checkup. The doctor will perform a physical and start keeping a detailed medical history.
The overvaccination of pets is currently a hot topic, Murray says. The question is, however, not whether to vaccinate but which vaccines to use and how often. What she calls the 'core vaccines'—those for parvovirus, distemper, adenovirus type 2, and rabies—are essential. 'These shots protect your dog from diseases that are very real, very common, and very dangerous,' she says. Additional vaccines may be necessary based on where you live, where you take your dog, and whether you travel.
Choose a reputable brand of dog food and discuss your choice with your veterinarian. In his first year, your puppy will be on food that is specifically geared toward younger dogs and will likely eat three times a day rather than once or twice.
An excellent measure against pet overpopulation, this procedure ideally should be performed between ages 4 and 5 months, which is before a female dog goes into her first heat and before a male enters puberty. A female dog who is spayed before going into heat is 2,000 times less likely to get breast cancer, Murray says. Males who are neutered before entering puberty have fewer behavioral issues, such as aggression toward other dogs and urine marking.
Puppy Health: Flea, Tick, and Heartworm Medicines
Most dogs should be on medicine year-round to prevent heartworm, a life-threatening parasitic infestation, Murray says. Fleas, often seen as just an annoyance, can actually cause severe skin problems and even anemia. Ticks carry multiple diseases (including Lyme disease and Rocky Mountain Spotted Fever). Your veterinarian can prescribe effective preventives for these two problems.
