There are many reasons why your dog may be aggressive, and it may require veterinary advice. Read about the causes of aggressive behaviour in dogs here.
Your dog has a personality completely unique to them – and like all dogs, they have different moods ranging from joyful to scared. If your dog is behaving aggressively however – either to people or other dogs - you should address it as soon as possible.
Aggressive dog behaviour can include:
• Aggression to strangers
• Aggression to family members
• Guarding resources (such as food, treats or toys)
• Aggression to other dogs in the household
• Aggression to unknown dogs
If your dog is showing any signs of aggression, first of all, consult your veterinary surgeon. Your vet will conduct a full examination to see if there is a clinical reason for your dog’s aggression such as pain, discomfort or any other physical cause.
If no medical explanation or treatment can be found, the vet can refer you to a professional behaviourist for help. Take a look at your pet insurance policy - some will cover these fees for your added peace of mind.
Although taking your dog to see the vet or behaviourist might seem worrying, you should never attempt to treat your dog’s aggression yourself, or ignore it and hope it will go away. If your dog’s aggression is not tackled quickly and appropriately, the problem can escalate and may result in serious injury to yourself and your family, other people or other animals, and even legal issues – and of course, you want to get help for your dog long before it gets this far! This is a problem that is far better - and far easier - tackled straight away.
Why is my dog aggressive?
All behaviours happen for a reason and occur as a result of the way the dog is feeling – and aggression is no different. A properly qualified and experienced behaviourist will be able to get to the heart of why your dog feels they need to act in this way, what their triggers are, and how to deal with this.
The fear response
Aggression in dogs nearly always comes from fear – as the purpose of aggression for a dog is one of perceived self-defence, and nearly always is with the intent of making things the dog regards as frightening or unpleasant stop, make them go away, or prevent them from happening in the first place
These fears can arise due to inadequate early puppy socialisation, past experiences, or the perception that valuable resources are under threat of being taken away. Some dog who have been roughly or inappropriately handled as a puppy or put in scary situations when they are too young to be able to do anything about it can also grow up to be more reactive as adults.
Since fear is the most common cause of aggressive behaviour in dogs, you should never punish your dog for growling or for any other display of aggression. Shouting at a dog for growling at something he is fearful of will simply compound his fear, may escalate the aggression, and quite likely his aggressive response will worsen next time.
What should I do if my dog is aggressive?
First of all, learn how to recognise how your dog is feeling. Every dog gives warning signals before they bite or attack – especially the first time - but owners aren’t always very good at reading them.
Dog aggression warning signs
There are several signals that your dog may give to indicate they are worried, fearful or feeling stressed, and if we recognise these, we can keep dogs feeling safe and stress-free, and so prevent a lot of canine aggression long before it starts. Often dogs bite out of self-defence because they feel that it is their only option as all their other warning signs have been ignored.
