When, Why, and How to Start Feeding Your Pup Grown-up Nutrition
As your puppy grows into an adult dog, he needs nutrition that keeps his body as strong as your love, and that means a high-quality, premium adult formula such as IAMS™ ProActive Health™ Adult MiniChunks
Why move your grown-up pup to a premium adult dog food? Because quality counts. It's crucial to continue his superb puppy nutrition into adulthood. Downgrading to a lower-quality brand at this stage of his life may upset his digestive system, and won't provide him with the same level of nutritional excellence he was raised on.
Think of a baby. When it's time to start giving him solid food, you wouldn't dream of feeding your child anything less than the best nutrition you can buy. The same is true for your maturing puppy. He needs the best age-appropriate food there is to help maintain his overall health.
Premium foods, such as IAMS, are specifically designed to provide your dog with a food that has:
What does it all add up to? A happy, healthy dog. With premium dog food, you can expect key indicators that contribute to providing your dog with a long, healthy life:
Founded on more than 60 years of research into canine nutrition, premium formulas from IAMS help maintain your dog's health and provide him with the nutrition he needs for a long life. Basic brands may not provide these benefits or match the level of expertise that goes into every bag of dog food from IAMS.
Your puppy's transition to adult food should begin when he approaches adult height. His breed type will also help determine when to switch. Small-breed dogs tend to mature physically much sooner than large-breed dogs. Follow these guidelines to help you decide when to switch formulas:
Large- and giant-breed dogs, those weighing more than 50 pounds when fully grown, might not be ready to switch to an adult food until they're 12 to 24 months old.
To avoid upsetting your dog's intestinal tract or causing diarrhea, make the change from a puppy formula to an adult diet over a period of four days by mixing the two foods in your dog's bowl.
How much food should you give your dog? Check the daily feeding recommendations established by the pet-food manufacturer and read the label. Dan Carey, DVM and Director of Technical Communications at IAMS, suggests using the recommendations, then weighing your dog each week. If he's gaining or losing weight and shouldn't be, slightly decrease or increase his daily intake, and weigh him again in another week.
If you have specific concerns about your dog's weight, talk to your veterinarian. He or she can assess your dog's needs and give you a feeding recommendation.
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.
