It’s common for dogs to bark. It’s their form of communication, they also vocalize themselves when they howl or whine.
Barking is a normal behaviour for dogs, but excessive barking can be concerning. Ongoing, excessive barking is your dog’s way of sending you a distress signal.
Why your dog barks

Alert or Warning
Many dogs will bark if they sense some type of danger or threat. The sound of this bark is usually sharp, loud and authoritative. Honing this instinct with training can help protect your home and family.
Environment
The barking occurs when your dog is exposed to loud noises, such as thunderstorms, firecrackers, or construction noise.
Excitement
Many dogs will bark while playing with people or other dogs. Even the sound of the bark tends to sound upbeat and possibly musical. This is a sign of playfulness and is common in young puppies.
Responding to other dogs
Your dog might be barking in greeting if he barks when he sees people or other dogs and his body is relaxed, he’s excited and his tail is wagging. Dogs who bark when greeting people or other animals might also whine
Anxiety
The most common reasons for anxiety in a dog is abandonment, fear of being home alone, loud noises, traveling, and/or being around strange people, children, or other pets.
