Understanding pet food consumers plays an important role in this competition to investigate purchase decisions. There are two aspects of pet food consumers, which includes pets that consume products, and pet owners who buy products. This research focused on two factors, palatability and emotion, that may affect purchase decisions from the perspectives of pet and pet owner. The objective of the first study was to investigate dog preference for various meats using the preference ranking test. Twelve beagle dogs performed the preference ranking procedure to rank five different meats: beef, chicken, lamb, pork, and turkey. Dog preference for cooked and raw meats were both tested during the study. In addition, a descriptive analysis of cooked meat aroma characteristics was conducted with four highly trained panelists to profile the meats. The results showed that dog preference for cooked and raw meats was similar, in which beef was preferred over chicken and pork. Specific cooked meat aroma characteristics such as meaty overall and brown/roasted might be intrinsic drivers of liking in dogs. The goals of the second study were to generate emotion terminology from both pets and pet owners and to investigate body languages and signs perceived by pet owners related to pet emotion. Four focus group sessions were conducted to gather insights from pet owners according to emotions they and their pets experienced. Lists of 38 and 55 emotion terms were generated for dogs and cats, respectively. In addition, lists of 33 and 62 emotion terms were created for dog owners and cat owners, respectively. Examples of emotion terms generated for pets and pet owners included excited, happy, anxious, and fearful. The validation of these emotion terms was conducted in the third study. The objective of the third study was to understand consumer (dog and dog owner) acceptance of granola-bar-like dog treats made with various sources of crisp and binder. Fifteen different kinds of treats were baked with three sources of crisp (rice crisp, white sorghum crisp, and red sorghum crisp) and five sources of binder (corn syrup, spray dried plasma, gelatin, albumin, and egg white). A home-use-test was conducted with 39 dog owners and their pets to evaluate the treats for overall liking, dog’s liking, appearance, aroma, and texture. In addition, emotion terms were probed during the test. The results showed that there was no significant difference for the owner’s overall liking and the dog’s liking among the treats. Positive emotions such as content/satisfied and happy were experienced frequently by the owners when dogs consumed the treats. Conversely, dogs were reported excited, happy, and eager when eating the treats. These studies demonstrated that a combination of palatability test and sensory analysis provided insights from both and pet and pet owners, which may be helpful for the pet food industry to understand the pet food consumers further.en-US© the author.
