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.
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.
We’re not talking about the “Sit. Shake.” kind of shake. Nor the fun way they shake off water starting from their nose all the way to the end of their tail. (FYI, dogs can shake off 70% of the water on their fur in just four seconds!)
No, we’re talking about that full-body trembling you’ve likely seen your pooch do from time to time. Why do they do it? And is it something you should be worried about? Let’s shake a leg and find out.
A majority of dog owners in an IAMS™ survey* (64%) think dogs shake because they’re cold. Other top responses were because they’re scared (57%) or anxious (54%).
High-fives all around because it turns out there are a number of reasons dogs shake, and all those are possible correct answers.

Just like their owners, dogs will often shiver when cold.
Opens a new windowDr. Tammie King, Applied Behavior Technical Leader at Waltham Petcare Science Institute, says: “Dogs shiver in response to falling temperatures. Dogs with short or no hair are especially susceptible. You should get them warm, put coats on them or bring them inside.” Same goes for you.

“Shaking is a response to epinephrine or adrenaline secretion — a sign of anxiety where the dog is on high alert,” says

You may notice this when you’re at the vet or there’s a situation where they feel threatened. Dr. Serpell also offers a way to help in some cases: “Identify what’s triggering the behavior. Provide them comfort. Going forward, you can gradually desensitize your pet to the thing it’s afraid of.” Unless it’s clowns. Those are always scary.
Trembling can also be a sign of serious issues like injury, poisoning or kidney disease. Opens a new windowDr. Jo Gale, BVetMed CertLAS MRCVS, Senior Manager, Global Science Advocacy at Waltham Petcare Science Institute urges pet owners to be vigilant: “If a pet is unwell in another way, they could be trembling.” If their shaking is accompanied by symptoms like diarrhea, limping or vomiting, you should consult your vet straight away.
