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’ve likely heard your dog let loose his inner wolf and belt out a few long howls. 73% of dog owners in a recent IAMS poll* believe they do this to communicate. This form of vocalization has a long history and is used for different reasons. Understanding more about howling will help you understand your pooch better.
Howling is an ancient trait wolves use to communicate with other members of their pack and other packs over long distances. They may be trying to locate a lost member, show off the size of their pack or warn of danger. It’s like a canine group text.
A wolf’s howl can be heard up to 10 miles away.
Each wolf has their own unique howl, so pack members know who they are, even miles apart.
Dogs instinctually respond to howling-like noises by howling themselves. Sounds such as sirens, other dogs, singing or your kid learning the violin is usually enough to get them to sound off.
Dogs are still very social animals; it’s just that now we’re their pack. When they miss us, they’ll howl in hopes we respond.
Opens a new windowDr. James Serpell, BSc, PhD, Professor of Humane Ethics & Animal Welfare at University of Pennsylvania School of Veterinary Medicine, explains it this way: “That [howling] is an attempt on the part of the dog to ask the owner basically, ‘Where are you so that I can rejoin you?’”
Dr. James Serpell doesn’t believe so. “My own research has shown that it is common across breeds. People think huskies may be more prone to group howling.”
Dogs going through separation anxiety may howl excessively when left home alone. Dr. Jo Gale, BVetMed CertLAS MRCVS, Senior Manager for Global Science Advocacy at Waltham Petcare Science Institute, says, “If you reinforce quiet behavior, they are less likely to continue howling.” You can do this by quieting your dog and then leaving for a very brief time before returning and rewarding them when they stay quiet. Gradually increase the time you’re gone to reassure them you’ll always be back.
