Aggressive Dog Behavior

Behavioral Modification

Examination of Treatment Options to Reduce Aggression:


There are several classes of aggression considered normal to dogs as part of their instinct for survival. The ASPCA web page presents one of the best reviews of the types of and risk factors for canine aggression.

However, our focus is social interaction, not survival. As pet owners we take on the role of “pack leader” in all aspects of life including training and medical care. The well-known trainer, Cesar Milan, focuses on lack of exercise and confusion over who the pack leader is as sources of aggression. These and other factors such as injury, illness, poor diet and major changes in home life are sources of stress and may result in aggressive behavior.

An overall way to look at it is, a content dog with a good sense of wellbeing has the ability to withstand stress and should be less aggressive. The Blue Spot Pets model takes into account physical, historical and neurochemical aspects to determine the appropriate course of treatment.

Regular exercise and a high quality diet are a good starting point for stress reduction. Dogs with pent up energy are likely to be frustrated and “take it out” on other dogs or the humans they associate with. On average, exercise should last 30 minutes to an hour. As a guideline, when the dog’s pace has slowed and starts to lag behind, he has had enough. However, exercise should not result in injury. If the pavement is hot, find a trail sheltered by trees with a cool surface to walk on. It is also a good idea to wet the dog down. They don’t sweat and the evaporation of the water will cool them.

Unfortunately, some dogs need more exercise than the owner is able to provide. With the constraints of modern life, time is always an issue. Social interaction with humans and other dogs may be limited. Solving an aggression problem becomes more complex. You may have been advised to treat the aggression with antidepressant drugs like Prozac. 

WE HAVE GOOD NEWS. There is a DRUG FREE solution.

Aggression is treatable through the Blue Spot Pets Brain Wellness Program. The basis of this unique program is in the field of neurochemicals (neurotransmitters) like Serotonin. Stress may “burn up” necessary neurotransmitters at an accelerated rate. The testing, analysis and nutrition provided in this program is designed to measure the level of NTs in your dog’s brain and balance them to within the normal range. There are a number of reasons for an imbalance of NTs. One of these is how well the digestive system is working. Testing in the Blue Spot Pets program addresses this as well as other NT balancing issues.

Is there a scientific basis for this program?

The answer is yes!

There is a great deal of academic data on neurotransmitters and how they are used in the brain. This data spans several species including both dogs and humans. The following is a brief review of two such studies concerning dogs.

“The Neurobiology of Pathological Aggression in Dogs”

In a study by Belen Rosado at the Veterinary School at the University of Zaragoza, Spain the researchers found that aggressive dogs showed significantly higher levels of cortisol (a stress related hormone) and significantly lower levels of serotonin (a neurotransmitter) in the blood, compared to normally behaving dogs. The lowest levels of serotonin were found in dogs showing defensive forms of aggression. This data indicates that methods used to increase the levels of serotonin to levels found in normal dogs should be an effective treatment for aggression.

 “The effect of dietary protein content and tryptophan supplementation on dominance aggression, territorial aggression, and hyperactivity in dogs” by Jean S. DeNapoli, Doctor of Veterinary Medicine at the Department of Clinical Sciences, School of Veterinary Medicine, Tufts University, Grafton, MA. 

Tryptophan is an essential amino acid the dog obtains from its diet. It is a precursor (building block) for the neurotransmitter serotonin. The theory tested was this. Are low protein diets and diets high in tryptophan associated with less aggression, reduced excitability and reactivity? The result of the study was that the most aggressive dogs were on high protein diets without supplements of tryptophan. Dogs on low protein diets with tryptophan supplements were the least aggressive. Adding tryptophan to a high or low protein diets reduced the level of aggression.

Ok, you have seen the science. Now, enjoy a feeling of security in your pets care. Discover how Blue Spot Pets treats your dog in a way similar to your doctor’s care for you. - Your MD uses a lab analysis, patient history and his medical knowledge to determine a course of treatment for you. But, he doesn’t leave it there. He “follows” your results and if needed, modifies treatment after subsequent checkups.

Blue Spot Pets provides a similar program for your dog. Our science officer provides a protocol of mealtime supplements to support the natural balancing of neurotransmitter levels in your dog’s brain. This protocol is based on a urinalysis, health history and with her knowledge of neuroscience. We recommend periodic retesting to determine the efficacy of the treatment and the need to modify the protocol.

As your dog’s system becomes balanced in a “normal” state, he is able to handle stress more efficiently and less likely to be aggressive. Learn more about managing aggression.
