Antioxidants are nutrients found naturally in the body and in plants such as fruits and vegetables. Common antioxidants include vitamin A, vitamin C, vitamin E, and certain compounds called carotenoids (like lutein and beta-carotene).
As cells function normally in the body, they produce damaged molecules called free radicals. These free radicals are highly unstable and steal components from other cellular molecules, such as fat, protein, or DNA, thereby spreading the damage.
This damage continues in a chain reaction, and entire cells soon become damaged and die. This process is called peroxidation. Peroxidation is useful because it helps the body destroy cells that have outlived their usefulness and kills germs and parasites. However, peroxidation, when left unchecked, also destroys or damages healthy cells.
Antioxidants help prevent widespread cellular destruction by stabilizing free radicals. More important, antioxidants return to the surface of the cell to stabilize, rather than damage, other cellular components.
When there are not enough antioxidants to keep peroxidation in check, free radicals begin damaging healthy cells, which, in turn, can lead to problems. For example, free-radical damage to cells of the immune system can lead to an increased risk of infections.
Because antioxidants play a key role in minimizing damage to human cells, such as those that make up the immune system, research examined the benefits of certain antioxidants on the immune response of dogs. The results of these studies indicated that antioxidants are important in helping dogs maintain a healthy immune system.
Even if a pet food is formulated to provide all of the essential nutrients required by a dog, it is of little value if the animal will not eat it. Quality pet foods are carefully formulated not only to be highly nutritious but also to be highly palatable.
Highly palatable dog food recipes contain various ingredients and raw materials, including palatants. Palatants help improve the smell, flavor, and texture of your dog’s food. Examples of palatants include fat, salt, proteins, yeasts, and other flavors that are added to make food taste better. Dry foods usually need extra palatants to make them more pleasant and appealing.
Palatability is a term used to describe how well a dog likes the taste, smell, and texture of a food. A premium dog-food manufacturer spends a considerable amount of time conducting controlled feeding studies to determine the right combination of ingredients and processing techniques to produce a nutritious, palatable food.
There are two ways to test and measure the palatability of a dog food:
First Bite: The first palatability test is called the “first bite” preference. This measures the dog's first impression of a food's aroma and appearance.
Total Volume: Because the novelty of a new diet can cause highs and lows in first-bite tests, a second test is conducted called “total volume” measurement. Total volume determines the staying power or ability of a diet to maintain the animal's interest over time. This is the dog’s overall choice of a food based on taste, texture, and nutrition for the entire test period.
Dogs can become picky eaters for a variety of reasons. Some of the reasons why dogs can become picky eaters include:
In comparison to humans, dogs have significantly more smell sensors than taste receptors. This implies that foods with stronger aromas tend to appeal to dogs more. While scent is crucial, less odorous meals like dry kibble can also improve your dog’s food palatability. A dog’s taste buds are hard-wired to sense the presence of fats as well as salt (but not necessarily salt flavor). Fat is frequently added to kibble to improve flavor and palatability without making the food stinky.
While taste and scent are some of the primary ways a dog decides if something is pleasant, palatability can also be influenced by a wide range of factors, such as the dog’s unique preferences and even the owner’s preference for meals and feeding times.
To make a dog eat food, you need to:
Everybody in the household needs to accept and follow the pet’s feeding plan from the beginning. You should be consistent and rigorously adhere to your dog's diet. If you decide to give your dog leftovers, choose to combine nutritious foods with kibble.
Offering your dog table scraps often promotes begging and throws off your pet’s diet. It can also lead to several health issues, including diarrhea and pancreatitis. Although human food is far more palatable, it is less healthy than canned or dry dog food.
Puppies need to be fed two to three times a day, or as your vet may prescribe. As they get older, you can gradually increase the serving size while offering meals just once or twice a week. Additionally, you must add some variety and deliver equal servings. Allowing a schedule also helps keep your dogs weight in check.

In order to obtain and interpret accurate results, palatability studies must be performed by experienced animal technicians and the data analyzed by research nutritionists. Feeding studies are conducted by offering an animal two bowls of food at the same time. Each bowl contains a different diet that has been carefully weighed and recorded.
The technician observes which food the dog chooses to eat first, and then records that as the first-bite preference. After a specific time period, bowls are removed, and any remaining food is weighed and recorded. Diets also are switched from left to right each day of the study to ensure that dogs are not eating one diet simply out of habit.
The total-volume measurement is determined by calculating the difference between the beginning and ending weights of each food. This procedure is repeated using the same two diets with the same group of dogs for five days. At the end of the five-day study, all observations and data are compiled and analyzed to determine the overall palatability of each diet.
Here is a quick look at some flavors that can appeal to your pet.
Meaty Flavor
Animal Fats
Gravy or Stews
Dogs are attracted by not only the taste of a food, but also to its sight, aroma, and texture. Dogs are particularly interested in the smell of food.
If you are wondering how to increase palatability of dog food, here are a few tips that might help.
Select The Right Protein
Whether your pooch prefers dry or wet dog food, remember that the choice of protein is extremely essential. The most palatable dog foods are ones that are available in different meaty flavors such as lamb, beef, and chicken.
Liquid digest is simply protein that is enzymatically broken down into amino acids, which are the building blocks of protein. The enzymatic process reduces large protein pieces to smaller protein pieces and free amino acids. By adding small amounts of acid, the enzymatic or digestive reaction is stopped, and a stable liquid ingredient is produced. After a dry-food formula is cooked, formed into kibbles, and dried, the liquid digest is sprayed evenly on the outside of the dry kibbles. This is called “enrobing.” Not only does the liquid digest make the food highly palatable, but it also adds to the overall digestibility of the food.
Yes. We use liquid digest made from chicken to enhance the palatability of dry foods and to contribute to the nutritional value of the diet. Some pet foods include flavor enhancers, such as onion powder, which simply mask the aroma and taste of the ingredients and provide no nutritional benefits to the animal.
