It is often said that dogs are excellent companions and with good reason. Indeed, these animals are extremely endearing, friendly and loyal. However, dogs can also be aggressive like any other animal. In fact, you may have already witnessed aggressive behaviour from your dog. Although this may be worrying, the first thing to do is to quickly identify the cause of this aggression. Knowing the source of aggression will help you find the best options to correct this unwanted behaviour.
Some diseases can cause aggressiveness in dogs. If your dog likes to walk with other dogs, but his behaviour suddenly changes to become aggressive, he may have a serious illness. It is better, in this case, to go to the vet to make sure everything is correct.
