In her new book, The Secret Language of Dogs, trainer and Animal Planet star Victoria Stilwell explores the ways recent canine studies show us how to better understand the hidden language of dogs.
Memory is crucial for problem solving, hunting of prey, smell recognition, facial recognition, and general learning. Dogs need to memorize environmental landmarks so they can find their way around as well as construct mental maps of where these landmarks are located. Although dogs use visual markers to navigate their surroundings, they rely more heavily on how things smell. This mental mapping is important for remembering territory and territorial boundaries as well as being able to reach a food source or an area of comfort and safety.
Dogs also need to have a good working memory if they have to find food for themselves. They have to remember that if the prey they are chasing goes behind a rock and disappears, it might still be there even though they can’t see it.
It’s believed not only that dogs have good olfactory memory and can remember smells for years afterward, but also that smell is linked to their emotional memory, just as it is in humans. The smell of a veterinary hospital may always elicit negative emotions, whereas the odor of a favored person triggers happiness and joy. Auditory memory is also important and is especially useful when it comes to remembering the sound, tone, and pitch of a human vocal signal that is linked to a certain action or behavior.

Dogs can not only recognize the voices of people they know but also learn and remember that different vocal pitches and tones mean different things. Their physical reading skills can help them determine what human vocalizations mean, and because people tend to speak in higher pitches when they are being affectionate and lower pitches when they are upset or angry, it is easy for dogs to learn the difference and respond accordingly. You can help your dog learn by being consistent with your vocal pitch as well as being aware of how to use tone when talking to your dog or giving cues. In general, the type of cue will determine the type of tone and pitch you use. You can use highenergy vocalizations to excite your dog into playing, for example, or to get your dog to come back to you when you call; use medium tones for everyday cues such as “wait” by the food bowl or “stay” by the front door when a guest is entering. You can use lower tones to tell your dog how you feel about a certain behavior, but take care not to frighten him into compliance. The canine memory is so good that he will truly remember and recognize the difference! Dogs that have been raised in positive, stimulating environments tend to have better memory function than dogs that have been raised in social isolation, because the more pleasant experiences a dog has in early life, the more chances its brain has to develop.
