Active dogs thrive on diets high in fat. To preserve a high-fat dry kibble diet, however, is a challenge. The IAMS research team met that challenge with an effective preservative system used in all our dry dog food products, such as IAMS™ ProActive Health™ Adult MiniChunks.
The preservative system features a special blend of mixed tocopherols. Tocopherols are antioxidants extracted from vegetable oils. There are four major types of tocopherols. Vitamin E, also known as alpha-tocopherol, is commonly used in dog foods, though a specific mixture of the different tocopherols protects against rancidity.
Our preservative system slows the rate of oxidation and allows for an extended shelf life.
Wet foods, such as IAMS™ ProActive Health™ with Chicken and Whole Grain Rice Pate, do not require preservatives because they are preserved by packaging. When the ingredients are mixed and ready for cooking, the mixture is packed into cans, trays or pouches and cooked in a retort. Similar in principle to a pressure cooker, the retort sterilizes and preserves the product.
The cans, trays or pouches are then cooled under conditions that assure product sterility and container integrity.
Thorough shelf-life testing is conducted on all our products. In general, shelf lives for various types of products are:
24 months for wet foods
16 months for dry foods
12 months for biscuits
By using a preservative system in our dry dog food and preservation through packaging in our wet dog food, IAMS makes sure the food your dog eats is well-balanced and nutritionally beneficial.
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.
