Fiber is important to your dog's health, providing bulk to move food through his intestinal tract. Some types of fiber can be fermented (broken down by bacteria) in the intestinal tract. This process creates short-chain fatty acids (SCFA), which are a key energy source for the cells lining the intestinal tract.
Most people are aware of fiber and its role in their diet. The beneficial effects of higher fiber levels in humans influence the way many people think about their own food—and their pets’ food. As a result, some pet-food manufacturers began to think like human nutritionists and make high-fiber diets for dogs. But high-fiber diets and the shorter digestive tracts of dogs don't always mix well. High fiber levels in dogs can cause digestive problems and interfere with proper nutrient absorption. Unlike humans, dogs are carnivorous, meaning their nutritional needs are better satisfied with meat rather than with plant materials.
For more than 60 years, pet nutritionists at IAMS™ have been studying diets to better meet the special nutritional needs of dogs. IAMS research shows that the optimal crude-fiber level for healthy dogs ranges from 1.4 to 3.5%. At these levels, nutrient digestibility is maximized.
An important characteristic of fiber is its fermentability, or how well it can be broken down by the bacteria that normally reside in the dog's intestine. This breakdown of dietary fiber produces SCFAs that provide energy to the cells lining the intestines. Different types of fiber vary in fermentability.
Fiber sources used in pet foods include cellulose, which is poorly fermentable; beet pulp, which is moderately fermentable; and gums and pectin, which can be highly fermentable.
Research has shown that moderate levels of moderately fermentable fiber, such as beet pulp, provide the benefits of energy for the intestinal lining and bulk without the negative effects of excessive stool or gas.
High levels of poorly fermentable fiber are used in some weight-reduction pet foods to dilute the calories in a serving. IAMS research found that this is not a good practice because high fiber levels can decrease the digestibility of other nutrients in the food and, therefore, can reduce the nutritional quality of the diet. You might also see more poop piles in the yard because of the indigestible fiber.
The key thing to remember about dietary fiber is that your dog's needs are not the same as yours. A moderate level of moderately fermentable fiber, such as beet pulp, provides proven nutritional benefits for dogs. Diets containing high levels of poorly fermentable fiber to dilute calorie content do not provide these nutritional benefits.
All IAMS products, including IAMS™ ProActive Health™ Adult MiniChunks, are formulated with optimal levels of moderately fermentable fiber to promote a healthy intestinal tract and enhance the well-being of your dog.

So you’ve found a new cat you can’t wait to bring home to your growing fur family.While it may be tempting to simply put all cats in a room and let them work out the introductions, this can cause a lot of stress for new and resident cats alike. Here area few ways to help the introduction go smoothly.
How Do I Decide Which Food to Feed?
When deciding which pet food is right for your pet, consider these three factors:your dog’s life stage, lifestyle and overall condition. Life stage refers to whether your dog is a puppy, an adult or a senior. Lifestyle refers to how active or inactive your dog is normally. Condition refers to your dog’s overall health and body weight.
How Often Should I Feed My Dog?

Puppies should be fed three times a day from weaning (3 to 6 weeks) to 4 months of age. After 4 months, they should be fed twice a day. Most dogs should continue to be fed twice a day throughout their life, although some pets do well with one feeding.
How Much Should I Give My Dog to Eat?
The amount to feed your dog depends on their age, size and activity level. Feeding guidelines, which list the daily-recommended portion, are included on all IAMS™packages. Start feeding with this amount and adjust according to your pet’s needs.Remember to divide the portion accordingly if you feed more than once a day.
When Should I Switch My Puppy to Adult Dog Food?
You should switch your puppy to a premium adult dog food like IAMS™ Lamb and Rice Recipe when they reach adult height. Small breeds that weigh less than 20pounds can usually start eating adult food between 9 and 12 months of age. Medium breeds weighing between 20 and 50 pounds can eat adult food at 12 to 14months of age. Large and giant breeds that weigh 50 or more pounds can transition from puppy food to adult dog food between 12 to 24 months of age. If you’re notsure, consult your vet.
What Is The Best Way to Introduce a New Diet to My Dog?
When changing your dog’s diet, it’s important to slowly introduce new food. Start by offering your dog’s daily portion in a ratio of 25% new food to 75% current food. During the next three days, gradually increase the amount of new food anddecrease the amount of the old food.
Should I Feed My Dog Both Wet and Dry Food?
Wet food is an excellent treat that can be fed alone or mixed with dry food. Although IAMS™ wet dog foods are nutritionally complete and balanced, you don’t have to offer wet food at every feeding. IAMS™ dry dog foods are formulated with high-quality protein sources such as such as chicken or lamb, and contain all the essential nutrients pets need. The crunchy texture of dry food also promotes healthy teeth and gums, and aids in overall good oral hygiene. In addition, some ofour dry dog foods contain a dental ingredient, sodium hexametaphosphate (HMP),to help block tartar build up on teeth during and after meals.

What Should I Feed My Dog If They’re Overweight?
If your dog is considered overweight for their breed and size, feeding a weight control dog food like IAMS™ Adult Healthy Weight, along with increasing their exercise and movement, can help address the issue. Don’t simply feed your dog less food — they still need to consume adequate protein, essential fatty acids and other nutrients even while they’re losing weight. And make sure to consult your vet before putting your dog on a weight management program.
What Should I Feed My Pregnant or Nursing Dog?
If your dog is pregnant or nursing, her nutritional needs have changed. The best food for a pregnant dog is a high-quality, nutrient-dense pet food formulated for all life stages, or for growth. A pregnant dog needs to consumer 25% to 50% more food than normal by the end of her pregnancy. A nursing dog should be fed a nutrient-dense diet such as IAMS™ Puppy and needs to eat two to three times her normal food requirement so she can nourish her puppies.
Why Does My Dog Need to Eat Protein?
Protein is an essential nutrient for dogs: It gives dogs amino acids that support healthy skin and a healthy coat, as well as muscles, tendons, ligaments and cartilage. High-quality animal-based proteins, like those found in chicken, lamb, fish and beef, contain all of the essential amino acids that dogs need to achieve optimal health.

Will My Dog Be Bored Eating the Same Food All the Time?
No. Boredom with food is a human trait. Dogs are creatures of habit and usually are happy with just one food. Dogs generally eat to meet their energy or nutritional needs. They have very short digestive systems, and if their diet is abruptly or constantly changed, digestive disturbances can occur. Also, constant changes can make your dog a finicky eater.
Is It OK to Moisten Dry Food?
Adding water will not change the nutritional value of a dry pet food. However, once moisture is added, make sure your dog eats it relatively soon — and also discard any uneaten portion to avoid spoilage. Feeding dry food is usually encouraged because of the benefit to your dog’s dental health.
Will It Hurt My Dog If They Eat My Cat’s Food?
Cats and dogs have different nutritional requirements and should not eat each other’s food. For example, cats require a much higher level of taurine in their diet. An occasional venture into each other’s bowls will not be harmful, but is not recommended on a regular basis.
Can I Supplement Your Dog Foods with Vitamins, Minerals,Oils, etc.?
Our foods are nutritionally complete and balanced. Adding vitamins, minerals or oils can offset the balance the food provides. One of the benefits of feeding a high quality product is that it has been carefully balanced in proper ratios to provide optimal nutrition — nothing needs to be added.
