Furthermore, what makes a dog’s hearing ultra special is that dogs can hear and respond to frequencies that humans cannot perceive. Vision Dogs’ visual acuity is estimated to be three to eight ...
[4] [5] In contrast, dogs bark in many social situations, with acoustic communication in dogs being described as hypertrophic. [6] While wolf barks tend to be brief and isolated, dog barking is often repetitive. [7] One hypothesis for why dogs bark more than wolves is that dogs developed vocal communication as a result of their domestication. [7]
The devocalization procedure does not take away a dog's ability to bark. Dogs will normally bark just as much as before the procedure. After the procedure, the sound will be softer, typically about half as loud as before, or less, and it is not as sharp or piercing. [3] Most devocalized dogs have a subdued "husky" bark, audible up to 20 metres. [4]
A drawing by Konrad Lorenz showing facial expressions of a dog – a communication behavior. y-axis = fear, x-axis = aggression. Both humans and dogs are characterized by complex social lives with complex communication systems, but it is also possible that dogs, perhaps because of their reliance on humans for food, have evolved specialized skills for recognizing and interpreting human social ...

A guide dog helps blind people walk safely. A hearing dog alerts deaf people to important sounds, such as a ringing alarm. Some dogs are medical response dogs that sense a medical issue and alert the handler. Seizure sensing dogs can be trained to sense epileptic seizures in their partner.
Dogs smile by pulling one or both lips back and may show all or some teeth. The "smiling" is often accompanied by other greeting behavior s, like approaching, wagging or even whining.
The top end of a dog's hearing range is about 45 kHz, while a cat's is 64 kHz. [ 3 ] [ 4 ] It is thought that the wild ancestors of cats and dogs evolved this higher hearing range in order to hear high-frequency sounds made by their preferred prey, small rodents. [ 3 ]
