Although dogs cannot talk like humans, there have many other highly effective ways of communication.
And much of it is soundless.
Dogs have very impressive ways of communicating some of which include smell, sound, barking, growling and hollowing.
Smell Dogs leave their smells around all of the time - and this is mainly for other dogs.
As they are less able to sweat through their skin as we can they do sweat through their paws.
Therefore, every time a paw touches the ground, it is leaving information for other dogs.
There are other ways in which a dog marks it presence such as using its urine or feces.
Male dogs only need to leave a few drops in important places to mark their presence and lifting their leg is a way of raising the scent.
Sound Dogs also communicate by sound but to a lesser extent than by smell.
The noises a dog can make include: Barking This is the one that we are most familiar with and it has many different uses.
Most owners can differentiate between the different kind of bark.
Dogs bark for a number of reasons; it could be to raise an alarm, for attention, as a demand or for a show of aggression.
Growling This is most likely a warning that the dog is unhappy about something and some dogs can be more vocal than others.
Howling Some dogs so howl more than others and in the wolves' pack, howling is a social activity as well as a method of keeping in contact.
Some dogs howl in response to certain noises they hear such as the TV, radio or musical instrument.
Touch Used less often touch is seen as an aggressive signal, similar to humans or can be seen as a sign off affection.
