Barking is an alarm sound. There is no threat of aggression signaled by the dog unless it is lower-pitched and mixed with growls.
In most cases, dogs that bark aren't being aggressive. Barking is basically a threat designed to keep others away, but it's not violent.
Aggression in dogs commonly includes body language or threat displays such as a hard stare, growling, barking, snarling, lunging, snapping, and/or biting. Aggression can be a normal form of communication in dogs, yet the display of aggression toward a person or animal is often considered undesirable or problematic.
Barking – A dog may bark as a warning, an invitation, a call of distress, or just because it's happy. There are many reasons for the bark, but it always means your dog is communicating something. If your dog is distressed or fearful, it may sound off in a repetitive high-pitched tone.
Fearful or Aggressive Barking
“If your dog barks when strangers come into the house, and he's either backing away or lunging towards the person repeatedly, that is probably in the aggressive/fearful barking range,” says Bloom.
An aggressive growl will be accompanied by snarling and snapping, while a playful growl is just a sound, accompanied by relaxed body movements (no tension).
The signs of a dominant and aggressive dog include staring; excessive low-range barking; snarling; growling and snapping; standing tall; holding ears erect; and/or carrying tail high and moving it stiffly from side to side. However, beware, often a dominant aggressive dog will give no sign before biting.
Barking is normal dog behavior and puppies won't grow out of it, but you can take positive steps to reduce it and teach your dog alternative ways to communicate. Barking can be a really important tool to learn what scares your dog or makes them uncomfortable.
Dogs may bark when calling out to other dogs, expressing emotion, being territorial or when trying to grab their owner's attention. Any noise, no matter how slight, can stimulate a barking response – for example rustling leaves, a banging window, lightning or thunder, or a ring of the doorbell.
If your dog is emitting 2-4 barks with pauses in between (frequency & duration) in a low pitch (pitch), this typically means a “Call the pack, there is danger” message from your little one. He notices something strange going on, is playing close attention to it, and is scared that the pack is in danger.
Social barking
Dogs are social animals, and your dog may bark just to greet other pups. If your dog is wagging his tail, has a loose body and is “play bowing,” he's probably just barking to be friendly.
There are multiple reasons that a dog may exhibit aggression toward family members. The most common causes include conflict aggression, fear-based, defensive aggression, status related aggression, possessive aggression, food guarding aggression and redirected aggression.
Will my dog outgrow the aggression? Puppies may go through a biting phase that they will often outgrow. Unfortunately in most cases, true dog aggression often escalates as the dog ages. While it may be natural to make excuses, all dogs are capable of causing serious harm.
Because of sexual and social maturity, dogs normally start to show aggression to people between 6 - 24 months of age. Why? The dog gets big enough to be able to scare people with aggressive behaviors while simultaneously perfecting their skills in how to do this during this period in their development.
As People Magazine reports: Based on the numbers gathered from Furbo users, Samoyed dogs bark the most, often up 52.8 times every day. The second chattiest canine, the Yorkshire Terrier, doesn't come close to the Samoyed's record… the little dogs bark about 23.6 times a day.
When your dog is barking, say “Quiet” in a calm, firm voice. Wait until they stop barking, even if it's just to take a breath, then praise them and give them a treat. Just be careful to never reward them while they are barking.
Some dogs bark at people or other animals to gain attention or rewards, like food, toys or play. 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.
Many blame poor training, hunger and boredom. But, what pet owners may not know is that barking, along with a myriad of other negative dog behaviors, is commonly rooted in anxiety and stress. By treating the anxiety and stress, a calmer dog will exhibit fewer symptoms of anxiety.
Aggression is a normal part of the way all animals behave. Often people only consider aggressive behaviour in a dog to be a problem when it reaches the extremes of biting, but it can include lesser degrees, such as “grumbling”, growling, snarling, teeth baring and snapping at the air without making contact.
A dog displaying aggressive body language will look large, standing with his head raised above his shoulders. His body will be tense, with weight either centered or over all four feet or leaning slightly forward onto the front legs.
Is training an aggressive dog possible? Yes. Aggression in dogs, whether it be toward a dog's owner or other dogs, is a serious behavior that should be adjusted with the help of a professional dog trainer.
Signs of dog aggression include raised hackles, stiffness, snapping, or lunging. If either dog shows aggression, separate them immediately.
Growling during play does not mean your dog is aggressive. It simply means they're having a great time. Your dog might even growl during a particularly pleasing cuddle or patting session. Many dogs growl talk to communicate contentment or as a greeting.
