Providing dogs with vitamins, minerals, and other nutritional components is important to their health and well-being. The best way to do so is by feeding a high-quality complete and balanced diet. Supplementing dog food often upsets the balance and may lead to a variety of health problems.
People supplement their dog's diet for different reasons. Some of these reasons might include:
It is important for concerned pet owners to realize that a quality dog food is carefully formulated to meet the caloric needs of the animal. In addition, the food provides the essential amino acids, fatty acids, vitamins, and minerals specific to the nutritional requirements of dogs. Quality foods are complete and balanced for a specific life stage or lifestyle. By adding table scraps or other supplements, the delicate nutrient balance can be disrupted.
The interaction between different minerals is very complex. Fortunately, this is an area of nutrition that has been the focus of extensive research throughout many years. Research has shown that not only are the individual levels of minerals in a diet important, but so is the proper balance. An excess of one mineral may affect the absorption of a second, and lead to a deficiency in that second mineral.
One common supplement is feeding additional meat. However, because meat contains 20 to 40 times more phosphorus than calcium, adding meat to a balanced diet will upset the calcium to phosphorus (or Ca:P) ratio, which is important for proper bone development and maintenance. This may prompt the animal's body to absorb calcium from the bones in order to reach the right balance. This is often the case in older animals that experience tooth loss due to the resorption of bone from the lower jaw. Ca:P ratio should range between 1.1 to 1.4 parts of calcium for each 1 part of phosphorus.
Excess amounts of calcium have been associated with several bone diseases affecting growing puppies. Owners of large-breed puppies in particular believe that their puppies require extra calcium for proper development of large bones. Adding yogurt, cottage cheese, or calcium tablets to the pup's diet will only upset the body's delicate mineral balance. Remember that large-breed puppies will consume more food and receive the calcium their bodies need by eating the recommended portions. The best way to support a normal growth rate is to feed growing dogs adequate—but not excessive—amounts of a balanced diet, using a portion-controlled regimen.
The Association of American Feed Control Officials (AAFCO) regulates the pet food industry and has established certain nutritional requirements for dogs and cats. These requirements are published annually in the AAFCO Manual. Only pet foods that have met the strict testing criteria established by AAFCO can carry the 'complete and balanced' statement on the label.
Most humans recognize a hug as a sign of affection and friendship. In an IAMS™ survey*, 83% of dog parents say their dog likes hugs too. But how do dogs feel about them? Bring it in! We’re going to try and get our arms around this question.

Sure, some dogs enjoy a good canine cuddle, but usually only with their owner or household members. Otherwise, they don’t really care for it. “Hugging is too much and overwhelming for many dogs and should be discouraged if the dog doesn’t know the individual very well,” advises

There are a number of reasons for this:
Hugging is a human behavior, not a dog behavior. They’re just not physically built for that kind of interaction. We stand upright, so we face people. Dogs are on all fours, so it’s an unnatural act for them. They much prefer a friendly sniff to greet other dogs.
To dogs, a hug is seen as a very dominant form of behavior; it feels like a stranger is trying to assert control over them. It can be quite stressful, especially if done by someone they’re not familiar with.
Since ancient dog days, canines’ first instinctive line of defense has been to run away from danger. Hugging takes this primal option away and can make them feel trapped and confined. Remember when you were a kid getting hugged by that loud great aunt you’ve never met at your dad’s second cousin’s wedding? That’s kind of what your dog is feeling. Who is this? What are they doing? They want to escape too.

You can usually tell by their body language, says

Don’t worry if your dog doesn’t want to hug it out. There are plenty of healthier ways you can show them you’re still their best friend:
