A New Look at Interdog Household Aggression

Updated: Dec 2, 2018

Most cases of interdog household aggression involved same sex pairs and the majority of cases involved female dogs. Half of the cases required veterinary attention prior to treatment. Instigators of aggression were typically younger and the second dog in the home. Owner presence was a major trigger for fighting. A proportion of dogs in the study had risk factors (multiple owners, adopted after the sensitive period for socialization, acquired from a shelter or pet shop, orphaned, the single puppy in a litter). Many dogs had other issues with social interactions involving fear and aggression, or phobias. Owners were generally compliant. The total number of fights, frequency of fighting, and severity of fighting was significantly reduced following treatment. Effective treatment recommendations included a leadership program to create consistent interactions with the owner, mood-stabilizing medication, and creating a hierarchy between the dogs.

This was very interesting, however, I have a question regarding your recommendations for 1. Leadership program 2. Creating a hierarchy between the dogs. These seem to be solutions taken from Alpha/Dominance Theory? As we know Dominance Theory was established as follows; based on a study of captive zoo wolves conducted in the 1930s and 1940s by Swiss animal behaviorist Rudolph Schenkel, in which the scientist concluded that wolves in a pack fight to gain dominance, and the winner is the alpha wolf.

Do you believe this solution still applies 80 years later? Thank you.
