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.
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.
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.
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.
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.
Small-breed dogs tend to have higher metabolism rates than their larger counterparts, which means they need a puppy feeding diet specifically designed for them. 'Small-breed dog food formulas are created to give your dog the right balance of nutrients,' says Debra Eldredge, DVM, a veterinarian in upstate New York and coauthor of The Dog Owner's Home Veterinary Handbook (Howell House). Here's what you need to know to feed your small-breed pooch.
The guidelines on the package are a great starting point, Eldredge says, but 'you have to customize [them] for your dog.' For instance, her family has three dogs who all weigh almost the same. But, one is getting twice as much food as the other two, and she's thin. 'She just burns it up,' Eldredge says. Your dog's breed and activity levels will affect how much food she needs.
Small-breed puppies, especially toy breeds, can be prone to hypoglycemia. To keep your dog’s blood sugar levels up, you might have to feed her more frequently and up the calories, Eldredge says.
Small-breed puppies grow quickly, so during the first six months, they need to eat more food and eat more frequently, generally three to four times a day. After six months, feeding two meals a day is usually sufficient. As your dog gets older and less active, her nutritional needs change, and she may need a formula for mature dogs. Her new food will generally have more protein and fewer calories.
Smaller dogs have smaller mouths and teeth, so their food is usually made in a smaller bite size, which is easier for them to chew and swallow.
Don't leave your dog's food out all day. Instead, pick it up after 10 or 20 minutes, Eldredge says. If food is available all day, she may eat out of boredom.
With dog food, your pet is on a balanced diet. Feeding her human food may throw off that balance. The occasional taste of chicken or eggs is okay, but don't make it a daily habit.
