Normally, the older dog will be dominant over a puppy (although this might change after a few months) but with two adult dogs, either one can be dominant. The dominant dog will take food and toys away from the other, push to be first for attention, and show dominant body language.
Conflict aggression, also called dominance aggression, can be a scary and difficult behavior for dog owners to manage. Puppies exhibit this aggression when testing limits and establishing dominance ranking within the family. They naturally strike out to see who is in charge of food, treats, territory, or toys.
If you catch your puppy misbehaving, try a loud noise such as clapping your hands or a loud "uh-uh" or a sharp “off”. Remember, reprimands need to occur while the behavior is happening, preferably just as it begins, and never after.
A puppy that is dominant can become aggressive as it gets older or can remain extremely confident. Either way, your relationship MUST begin at the early ages where the puppy is still very impressionable & bad habits are not reinforced to the point of no return.
Most dogs assume a neutral or submissive role toward people, but some dogs will challenge their owners for dominance. A dominant dog may stare, bark, growl, snap, or even bite when you give him a command or ask him to give up a toy, treat, or resting place.
The act of holding a dog down forcibly as a correction is generally called the "dominance down." It is inappropriate, ethologically absurd, and completely counterproductive when interacting with dogs.
Work with each dog individually first, then together once it is safe to do so. By learning to sit or lay down in the presence of a resource, dogs learn to remain calm in a situation that may have previously triggered a fight. If fights are caused by alliance aggression, independence training may be helpful.
Seperate. If the puppy is demanding attention that the older dog doesn't want to, or is not able to, provide, step in between your older dog and your puppy. Direct your older dog to his quiet place and distract your puppy by taking him to another part of the house and providing him with a toy.
In one posture, hold the pup over your head, firmly supporting him with both hands and stare into his eyes (staring is a dominant behavior to the dog). Maintain this position until the pup has been still for 10 seconds. He must be still for that length of time or he hasn't submitted to you.
1 No matter the reason a dog becomes aggressive, bared teeth are usually a sign he is being pushed past his comfort zone. If you see a dog with this type of body language, it's best to leave this dog alone. Avoid eye contact and carefully step away from the dog.
Dominant dog body language
When your dog is feeling confident and dominant, he or she will have a strong, positive body position. There will also be signs of alertness: rigid muscles and tail; raised fur; an attempt to make direct eye contact; and a closed mouth, sometimes accompanied by a soft growl.
A puppy that shows aggression toward people, such as growling, snapping, or biting could be doing so for a variety of reasons. It may be fear, stress or anxiety, territorial behavior, or medical issues. Breeds that were bred for guarding may show protective behavior around your property.
When Can You Start Training Your Puppy? Training a puppy starts as soon as you bring them home, which is typically about 8 weeks of age. At this young age, they can learn basic puppy training cues such as sit, stay, and come.
If you catch your puppy misbehaving, try a loud noise such as clapping your hands or a loud "uh-uh" or a sharp “off”. Remember, reprimands need to occur while the behavior is happening, preferably just as it begins, and never after.
Most often a dog's aggression is motivated by fear, anxiety, conflict about what to expect and what to do and the anticipation of possible punishment (see Aggression – Diagnosis and Overview, (Dominance, Alpha, and Pack Leadership – What Does It Really Mean?, and Canine Communication – Interpreting Dog Language).
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.
