Dogs apprehend their surroundings through their respective senses just as humans do. However, the canin senses differ from our human ones in many ways.
Dogs have a significantly larger olfactory bulb than humans and accordingly they have much more olfactory cells. The scenting ability leads the puppy to its mothers’ teats and ensures its survival from the very beginning. For all its life your dog explores its world mostly with its nose. This sense differs from breed to breed.
The larger the nose is the larger the space for olfactory cells. They smell human emotions, even diseases; they smell the biochemical processes of our body.
Sense of vision
Our dogs’ world is much less colourful than ours. Humans have 3 spectral types of cones of photoreceptors – dogs only have 2. That is why they recognize colours different from us. Dogs can see blue and green and they are less sensitive to red colours as they do not have the according receptors.
Our dogs have a very high visual discrimination for moving objects. Quick picture sequences of up to 80 pictures per second can easily be recognized as single pictures.
Sense of hearing
Dogs can detect sounds far beyond the upper limit of the human auditory spectrum. Even when a dog sleeps it can detect and locate sounds long before the human ear is able to. The fact that dogs have ear mobility gives them the edge of an excellent perception. By the way, dogs use one ear first in order to locate a sound before the second ear is used to deal with it.
Sense of taste
The dogs’ sense of taste is less marked that the human one. Dogs are able to differentiate tastes but for them there is only tasty, neutral and distasteful. However, dogs have different opinions of what is tasty and what is not. Deciding that, dogs use their sense of smell. If this sense does not signal tasty food the sense of taste is mostly not tempted. The primary function of the dogs’ tongue is not tasting but for drinking water and panting in order to cool down.
Sense of touch
With this sense dogs differentiate warm, cold, hard or soft. Especially in the darkness this sense is important because its whiskers on the chaps, the eyebrows, the ears and the outside legs play a decisive role.
Dogs have their own body language. They are always communicating with humans and other dogs, without us even being aware of it. We need to learn their language; we need to interpret and understand them in order to avoid misunderstandings.
With our support you will learn to understand your dog and to interpret its signals right.
