All of my dogs communicate with me using different vocalizations, along with facial expressions and body language. I know when Beau is telling me I need to fill the water bowl, or he's hungry, wants to go out to potty, or out to chase some FLB, or is bored, or wants affection, or wants something, but he's not sure what! The same is true for Maddy, Lucia, and Luc. Much of our communication with each other is silent; it's all in the eyes, and then body language.
