Healthy joints and proper weight are especially important for dogs that grow to be more than 50 pounds. But not all large- and giant-breed adult dogs have the same nutritional needs. Is your dog getting proper exercise? Is she about to have puppies? Special conditions can dramatically affect your dog’s nutritional demands. Giving her a food specially formulated for her large size, life stage and activity level is the easiest way to make sure she’s getting the nutrients she needs.
To address the special needs of your large- or giant-breed dog, look for these features:
These components are key to good nutrition. Look for them in treats, wet dog food, or dry dog food, such as IAMS™ ProActive Health™ Adult Large Breed.
Joint health is a big concern for owners of large- and giant-breed dogs. A large- or giant-breed formula that contains high-quality protein can help nourish healthy joints. Vitamins and minerals help promote the production of cartilage. Also, keeping your dog at a healthy weight will help minimize joint stress.
Dogs with lower activity levels and dogs that have been neutered or spayed are all prone to weight gain. Controlling your dog’s weight is an important step toward protecting against the health effects of excess weight, such as diabetes or joint health problems. If you use a weight-management food, look for these characteristics:
Pregnant dogs have substantial nutrition requirements. Starting in the seventh week of her pregnancy, a mother dog will need to increase her energy intake up to 50% by the time she gives birth and increase it even more when she starts nursing her puppies. Because she may lose her appetite at times, it's important that she eats a nutrient-dense food. A complete, balanced puppy formula can give her the extra nutrients she needs. But avoid puppy food created for large and giant breeds; these formulas contain specially adjusted levels of energy and minerals that may not be sufficient for a pregnant or nursing dog.
Dogs who grow to be more than 50 pounds are considered mature or senior at age 5 or 6, which is earlier than small-breed dogs. So, it’s critical to make a proactive transition to a specially formulated mature diet, such as IAMS™ ProActive Health™ Mature Adult Large Breed, to help keep your dog healthy and active as she ages.


Since we cannot directly communicate with our dogs, there are certain behaviours and actions that immediately concern us. One of these behaviours is a dog shaking. No, not the fun way they shake off water starting from their nose all the way to the end of their tail. 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?
A majority of dog owners in an IAMS™ survey* (64%) think the reason behind a dog shivering is that they are cold. Other top responses were because the dogs are scared (57%) or anxious (54%). High-fives all around because it turns out there are a number of reasons why dogs shake, and all those are possible correct answers. Here are some probable reasons behind a dog trembling:
Just like their owners, dogs will often shiver when cold. Dr. Tammie King, Applied Behaviour 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.”

“Shaking is a response to epinephrine or adrenaline secretion — a sign of anxiety where the dog is on high alert,” says James Serpell, B.S., Ph.D., Professor of Humane Ethics & Animal Welfare at the University of Pennsylvania School of Veterinary Medicine. 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 behaviour. Provide them comfort. Going forward, you can gradually desensitise your pet to the thing it’s afraid of.”

This is probably the most comforting answer to every dog owner’s concern. Apart from being a response to anxiety or stress, a dog’s trembling can also be a result of excitement. This trembling or shaking is not a matter of concern and will stop once the animal calms down.
Trembling can also be a sign of serious issues like injury, poisoning, or kidney disease. Dr. 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 diarrhoea, limping, or vomiting, you should consult your vet straight away.
Shaker syndrome has been observed in white dogs of smaller-sized breeds. It causes shivering in a dog’s entire body. The precise cause of this syndrome is not yet known; however, your vet will be able to prescribe medications upon close examination.
Old age is also a pretty common cause of shaking and shivering in dogs. This is because age reduces tolerance to even a slight amount of cold. Besides that, shaking can also be a result of other old-age-related issues like joint pains or weakening of limbs.
As mentioned earlier, you should immediately consult a vet if, along with shaking, your dog is also experiencing vomiting, limping, or diarrhoea. Even though shaking is a common symptom of old age-related issues, you must take your dog to the vet. If they are suffering from joint pain, early treatment is necessary. It is also advisable to visit a vet if your dog’s shaking or shivering hasn’t stopped even after a few minutes.
Additionally, if you ever notice violent shaking in your dog, it might actually be a seizure. In such a case, rush to an emergency room as quickly as possible.
