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.

We asked dog owners* how many hours a day they think their adult dog sleeps. The answers averaged around 9.7 hours. Truth is, dogs normally sleep around 12-14 hours a day. (Cats sleep 12-16 hours, which is why it’s called a “catnap,” we presume.) “Normal” can depend on lots of things. Bigger breeds definitely need more z’s. Older dogs tire quicker and sleep more. Growing puppies need up to 20 hours a day. Being cute must really be tiresome.
But why do they sleep so much? We’re not going to let sleeping dogs lie; we’re getting to the answers.
Dogs spend less time in deep REM sleep, so they’re able to wake quickly and be ready to go — whether it’s responding to danger or the opening of a bag of chips. It also means they need to doze more often to make up for that lack of truly restful sleep.
In general, carnivores need more rest. “In their wild dog and wolf days, it was a hunt for food, bringing down large prey, then feasting,” says
Opens a new windowDr. Jo Gale, BVetMed CertLAS MRCVS, Senior Manager, Global Science Advocacy at Waltham Petcare Science Institute. “They’d spend a long time digesting and may not eat for a few days. There’s a tendency to conserve energy.” Just think about how you feel after eating a huge steak. Incoming meat coma. Goodbye, belt. Hello, sofa.
Yawn. When owners are out of the house, dogs often sleep simply because they’re bored. They’re not into books and haven’t quite figured out how to turn on the TV, so why not catch a few extra winks? Plus, they want to be super refreshed when you come back home in the evening.
Some dogs like to sleep longer and some dogs are just lazier than others. According to
Opens a new windowDr. Tammie King, Applied Behavior Technical Leader at Waltham Petcare Science Institute, “You might see more sleeping after intense exercise or they’ve gone to a pet sitter or boarding center due to high stimulation.” There’s usually no cause for concern unless they seem lethargic and lose interest in playing or eating, or begin listening to a lot of emo music.
Their wild days long gone, dogs have adapted their sleep schedules to match humans’ sleep schedules. Sort of. They still might get you up in the night or early morning before your alarm goes off. It’s best to exercise them in the morning and evening so they’re more tired — and have used the facilities — right before everyone else goes to sleep.
Now, the only question remaining is, what do you think your dog dreams about?
