Dog aggression can be related to fear, prey drive, socialization issues, and guarding territory, among other things. Most aggressive behavior in dogs stems from fear and anxiety, rather than the desire to hurt others. A certified animal behaviorist can help you safely deal with your dog's aggressive behavior.
If your dog is showing any changes in their behaviour, especially if they have started showing aggression suddenly, you should contact your vet as soon as possible. Aggression tends to get worse over time and can lead to serious injuries to you, your dog or other people and pets so getting help is essential.
Do not wait for someone to be bitten. If your dog does any of the following, it's time to look for expert help in person: Growls, barks, snarls, snaps or lunges at people on walks. Shows aggression toward visitors to your home.
Many older dogs show increased aggression, anxiety, or compulsive behaviors. These behaviors are aggravated by body inflammation, sensory changes, and cognitive decline.
Infectious agents such as rabies, hormonal imbalances such as hypothyroidism, psychomotor epilepsy, hyperkinesis, neoplasia, and a variety of genetic and metabolic disorders can cause or predispose a dog to aggression.
Avoid triggers. You cannot expect your dog to behave until they have learned how. For example, if you know your dog has become more aggressive in high-energy play situations, stop going to the dog park until your dog has learned to remain calm. Reinforce calm behavior with rewards.
If your dog has an aggression problem, it's crucial to take her to a veterinarian, before you do anything else, to rule out medical issues that could cause or worsen her behavior. If the veterinarian discovers a medical problem, you'll need to work closely with her to give your dog the best chance at improving.
Treatment. It's important to keep in mind that there is no such thing as a cure for aggression. Aggressive behaviors are managed and reduced through proper treatment with a veterinary behavioral professional. It's also essential to understand that aggression is a behavioral problem, not an issue of obedience.
Sudden behavior changes in your dog can be concerning, whether it's an aversion or fear of something they used to enjoy — think rough-housing with other dogs or daily trips to the local dog park — or a new habit that's appeared out of the blue, like barking out the window or guarding their toys.
Some common signs that it may be time to put your pup down include the inability or refusal to eat or drink, labored breathing, an inability to get up for potty times without help, urinary or fecal incontinence, and immobility. Essentially, this can come down to your dog's quality of life.
Dogs that have a history of acting aggressively towards people should not be re-homed. Even if the dog acts aggressively towards children but does well with older people, the dog should not be rehomed for the simple fact that it is a liability.
While most dogs are well-suited to life with their human companions, not all are. Aggressive dogs can cause serious harm to you, your family and anyone else you come across in some situations. Dog aggression can be dealt with, but it takes a lot of training, patience, understanding and caution.
Euthanizing for Behavior Issues
There is primarily only one reason dog owners consider euthanizing their dog for behavior issues. That issue is moderate to severe human aggression. There are other behavioral instances where euthanasia is a consideration, but human aggression is the most common.
Any breed can produce an aggressive puppy
Often puppy fear can become aggression. Positive reinforcement, punishment-free obedience training is one way to create a well-behaved, well-mannered dog and prevent fear aggression in puppies. Puppy aggression is not breed-specific.
Behavioral changes can be your first indicator that something is wrong with your dog. If interest is lost in playing games, going for walks, eating, and sudden lethargy are good key indicators that something is wrong, and your dog is trying to tell you in their own way.

LEVEL 3—A SINGLE BITE WITH SHALLOW WOUNDS
Whatever the reason for a Level 3 bite, whether rough play that escalates, fear, poor socialization, or something else, this level of aggression must be dealt with. The dog should be taken to a vet or trainer as soon as possible.
Straight off the bat you should be correcting your dog's growling and/or snapping with a firm “no” at the onset of the behavior. When he stops growling, reward him with a “good boy”, or in the beginning, a treat if it's handy at the exact moment of training so that he knows what he is being rewarded for.
Things You Should Do When Working with an Aggressive Dog:
Make sure your dog is getting enough exercise and other canine enrichment activities. Maintain a calm demeanor around your pet. Use positive reinforcement and reward-based training techniques. Purchase and use a muzzle if your dog bites or you suspect he may.
Dogs in the same household can become aggressive toward each other for a variety of different reasons. Aggression may be dominance-related, territorial, possessive, or caused by fear/anxiety. Some dogs have “alliance aggression”.
Your vet can provide a thorough exam, check for pain or illness, and check blood work to search for medical issues that might be causing or contributing to your dog's behaviors. In addition, your vet may suggest specific natural supplements or prescription medication address the behavioral concerns.
Stay calm, and back away slowly. Instead of screaming, or yelling at the dog, speak to him in a soothing tone as you slowly back away. Don't make direct eye contact. Staring in the eyes of an aggressive dog may prompt him to attack.
