All dogs will display some level of aggression or reactivity at some point in their life, so learning how to address this type of behavior is critical for any dog owner or dog trainer.With a little knowledge and preparation it is easy to prevent almost all aggression, and to quickly address any aggression issues as they begin to emerge, before they develop into problems that can quickly decrease the quality of life for dog and owner alike.These days, I’m pleased to say that many owners understand the importance of early puppyhood socialization. Unfortunately, far fewer owners understand the important of maintaining that socialization through adolescence and adulthood, when dogs naturally become more shy and stand-offish. All too often, a dog will get into a single dog fight that will scare their owners into avoiding other dogs, depriving their own dog of the social interaction they need for rehabilitation. Without ongoing positive social experiences, the dog’s sociability only deteriorates further, resulting in self-reinforcing, downward spiral of de-socialization.As soon as you recognize any developing reactivity or aggression you should treat it. The sooner you do, the easier it will be. And the methods used in the treatment of dog aggression are remarkably similar to those used for prevention, except that treatment usually takes dramatically longer.Recently though, new techniques have been developed to accelerate and maximize classical conditioning, progressive desensitization and ultimately, re-socialization. These methods make it possible to rehabilitate dogs as quickly and thoroughly as possible.
