Found in the blood and in the fluid that surrounds cells, sodium maintains the cellular environment and prevents cells from swelling or dehydrating. Sodium is also important for maintaining proper nerve and muscle cell function.
Meat, poultry, fish, and eggs are good sources of sodium.
Sodium also might be included in commercial pet foods in the form of table salt (sometimes listed on the ingredient panel as salt). Salt is an important palatant for animals, as well as for people.
The Association of American Feed Control Officials recommends that dry dog foods contain at least 0.3% sodium for both maintenance and to support normal growth and development. This is the minimum recommended levels.
While high sodium intake might cause increased thirst and water consumption, the extra sodium is excreted in the urine of dogs. Healthy dogs are able to consume diets with higher sodium levels than those found in most commercial pet foods without increased blood pressure or gain in body water.
Therefore, the sodium level in commercial pet foods is not a cause for concern in healthy animals.
A veterinarian might recommend decreasing a dog's sodium intake if the animal has some types of kidney, liver, or heart disease, in order to help decrease high blood pressure or the accumulation of excessive body fluid.
Although older dogs might be more likely to develop these diseases, healthy older dogs do not require a low- or reduced-sodium diet.
The sodium level in our dog foods is appropriate for a healthy dog. The sodium content in these foods is balanced in proper proportions with energy, other minerals, vitamins, fats, proteins, and carbohydrates.
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.
