Diet plays a central role in your dog’s overall health and well-being, and it stands to reason that you want to provide your dog the best possible source of nutrition in the dog food you choose. But some nutrients, like L-Carnitine, may be unfamiliar or completely foreign. Learn more about this vitamin-like compound and how it can help your dog maintain a healthy weight.
Carnitine, or L-carnitine, is a vitamin-like compound made in the body from amino acids. It's found naturally only in animal-based protein sources. It has been used to help with fat metabolism in other species, and recent scientific studies show that it can help reduce weight in overweight dogs.
This water-soluble substance attaches to fatty acids, transporting them into cellular mitochondria, the part of the cell that converts fat into a usable form of energy. There, they are broken down through oxidation and converted to energy for all tissues, including the heart, liver, and skeletal muscles. Through this process, carnitine helps reduce the storage of body fat and the amount of fat in the bloodstream.
In a study conducted by The IAMS™ Company, overweight dogs were fed similar diets. One group was given a diet supplemented with L-carnitine while another group received a diet without supplemental L-carnitine.
After seven weeks, the group that received the diet without supplemental L-carnitine lost 1.8% body weight compared to 6.4% body weight loss from the group that was fed the L-carnitine supplemented diet. Likewise, body fat was reduced in each group by 2.4% and 4.6%, respectively.1 The study found that L-carnitine promotes loss of body weight and body fat in overweight dogs.
IAMS™ ProActive Health™ Adult Healthy Weight is formulated with L-carnitine that helps turn fat into energy, providing a path to help keep him fit for life.

You’ll do anything to keep your puppy healthy and happy—IAMS™ is just the first step. Here’s some extra advice to help your puppy stay extra healthy.
Step 1: Begin with a play session and praise to relax your puppy. Then get on the same physical level as your puppy. With a large dog, kneel next to him while he's in the sitting position; with a small puppy, place him on a grooming table or a countertop.
Step 2: Place one hand over the top of the puppy's muzzle as shown. Hold the pill in your free hand and then gently open his mouth with that hand.
Step 3: Place the pill in the center of the tongue as far back as you're able to reach. Then close your puppy's mouth and hold it shut while you blow gently but quickly at his nose. This will cause your dog to swallow before he has a chance to spit the pill out. Give him a treat immediately afterward to ensure that the pill has really been swallowed. End each session with play and praise.
Just like you, your new puppy needs high-quality health care. Before you run into any dog health issues, ask a friend or your local humane society to recommend a veterinarian, then choose one with these factors in mind:
Once you've narrowed your choices, visit the veterinarian's office. Inspect the facility and talk to the doctor about your new puppy. If you like what you see and hear, arrange a time to bring your puppy in for an initial examination. It's a good idea to visit the veterinarian within the first three days after you bring your puppy home to make sure he's in good health. The veterinarian will probably check:
