Understanding how animals eat can be quite complicated. For instance, it's interesting to note that when a dog vomits after eating, it can actually indicate how much the dog enjoyed the food. This behavior, described by Pat Moeller as a "gulper," occurs when a dog is so excited by the smell of food that it eats too quickly, leading to an overfilled stomach which causes it to expel the meal. While this may seem unpleasant, it suggests that the food was highly appealing to the dog.

Fortunately, the team at the AFB Palatability Assessment Resource Center has various methods to assess the appeal of pet food beyond observing vomiting behavior. They can use different techniques to determine how much pets like certain foods, thus providing insights into pet food popularity without the awkward implications of regurgitation.
