That's because barking is a dog's way of expressing a wide range of feelings and thoughts, such as joy, happiness, fear, or even a warning of danger.
Dogs may bark like this when they don't want to be alone or when they don't know what to do because they're getting mixed signs from different family members.
The same way that yelling can mean different things, so can whining. We usually think of whining as a bad thing, but dogs don't always feel bad when they do it.
Howling is the head-back, deep sound that most people think of when they think of wolves.The grey wolf, the parent of our dogs, used to howl.
If, on the other hand, your dog is wide-eyed and alert, it could be his way of getting your attention and asking for some love or playing.
When a dog growls at a person, another dog, or an object that scared it, it is often trying to warn them away. It means that if the growl isn't paid attention to, a dangerous attack could happen.
It's nothing to worry about when a sleeping puppy grumbles, yaps, or whimpers softly.This mix of sounds simply means that a dog is in a deep stage of sleep, similar to our REM sleep.
Don't be fooled: sneezing isn't always caused by nose irritation, allergies, or a cold in a dog. Many dogs sneeze when they are excited or want your attention.
When your dog snorts for more than a few seconds, it can sound like he or she is choking. This is called a backward sneeze, and it is often a sign of an allergy or stuffy nose.
