Warning Signs of Potentially Dangerous and Aggressive Dogs
Sometimes, dog owners find behaviors in their canines that are far from what would be expected of ''man's best friend." Such behavioral issues are often ignored or excused with phrases such as ''he will grow out of it," ''it's just a phase,'' or ''he only does it every now and then." Sugar-coating such issues, however, does not help at all and, in many cases, these behaviors are likely to escalate and exacerbate if left untreated.
Signs of Potential Problems That Should Not Be Ignored
Growling is a warning sign that should not be ignored. While some people appreciate growling because it indicates that the dog is warning them before biting, a growl should not be underestimated because it may indicate that the dog has a low-level threshold or is weak-nerved.
Biting is, of course, the most obvious act of aggression that dogs express. The bite does not have to break the skin to be considered a significant threat. Often times, owners start seeking help once the dog has bit somebody, which is too late. In many cases, signs of increased aggression were ignored or they may have been too subtle to be noticed by the inexperienced eye.

As seen, the signs are all out there. It is very harmful to ignore them in the hopes that they will disappear. Unfortunately, these behaviors often return and grow in intensity if they are not nipped in the bud. If your dog displays any of these signs, please don't try to solve them on your own, but consult with a veterinary behaviorist or a certified applied animal behaviorist.
Possible Causes of Aggressive Behavior in Dogs
Painful Medical Conditions
It is very important to have a veterinarian rule out any physical conditions that might be affecting such behavior, especially if the unwanted behavior is abnormal and/or sudden. Even the most docile dogs can sometimes become quite aggressive if they are in pain. An example of this that is quite common is when a very well-tempered dog suddenly snaps when its head is touched because of an underlying painful ear condition.

Another issue that may cause behavioral changes is a condition called ''hypothyroidism." It is certainly worth discussing with the vet to see if your dog has this condition. All it takes to rule it out is a thyroid blood panel.
Hormones also play a role in aggressiveness. Well-behaved male dogs suddenly become aggressive when they detect a female in heat nearby. While neutering may help a male dog have a better disposition, it is not really a ''cure-all'' for major behavioral problems that are not hormone-related.
