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.
Dogs use a range of sounds to communicate with us and each other. Just as important is the body language they use to tell us how they feel or what they need. How well do you know your pooch’s unspoken cues? Read on to find out.
Dogs often stare at their owners because they love them. They want to make sure you’re okay or find clues for what you’ll do next — like making sure you’re not going for a car ride without them.
We love it when dogs do this, too, which has led to this trait being even more prominent.
Opens a new windowDr. James Serpell, BSc, PhD, Professor of Humane Ethics & Animal Welfare at University of Pennsylvania School of Veterinary Medicine, explains: “We've selected dogs for this behavior. Humans love that dogs look up at them in admiration, intense loyalty. One frequent observation researchers have made is that people who handle wild dogs ... they don't look their handlers in the eye like domesticated dogs do.”
Dogs have great hearing. High-frequency sounds that humans can’t hear are especially interesting to them. Head-tilting helps them track down the source. Owners find these head tilts super cute and often reward this behavior, which, of course, makes them do it more.
Dogs yawn when they’re tired, but it’s also a possible sign they’re stressed, impatient or frustrated — like when they’re in the vet’s office, or when you won’t throw that ball you’re holding already!
In a recent IAMS poll,* 90% of dog owners said their pet sits or lays on their feet and 100% of dogs said they love their owners. Dogs are very social creatures and this is a way for them to connect and be close to you. Plus, it keeps your feet warm.
Often called “raised hackles,” dogs do this when they’re nervous, threatened or showing aggression. It’s an adaptation from their wild days of attempting to make themselves look bigger.
Opens a new window Dr. Tammie King, Applied Behavior Technical Leader at Waltham Petcare Science Institute, offered this insight to keep in mind: “What’s important when talking about a dog’s body language is to not take one thing in isolation. You’re at risk of misinterpreting what the dog is trying to say to you. Context is everything.”
So be sure to pay attention to what your dog isn’t saying to keep them healthy and happy. Serving them
