Research Report from the Journal of the American Veterinary Medical Association

Results pertaining to Conspecific Aggression between two or more dogs living in the same household

Research has shown that nearly one-third of the typical North American dog loving homes contain two or more dogs. In a multi-dog-household, arguably the MOST disturbing scenario occurs when there is an aggressive incident between the dogs living together in the same house.  We call this, Intra-Household Conspecific Aggression.  Whatever you call it…it’s no laughing matter!

These unfortunate incidents are not only disturbing for the peace and harmony of the humans living in the home…but they can be seriously dangerous for the dogs and the owners who try to intervene and break up the fight.  A scientific report published in the Journal of the American Veterinary Medical Association was commissioned to specifically assess the characteristics of the dogs involved in these aggression cases.

Researchers Kathryn Wrubel, Nicholas Dodman and others recruited thirty-eight pairs of dogs that came to the Animal Behavior Clinic at Tufts University of Veterinary Medicine in Grafton, MA, specifically because there were aggressive incidents between the housemate dogs.  The research team then conducted in-depth interviews and questionnaires to determine the characteristics of the dogs involved in these incidents.

Here are some statistics that many dog owners might find surprising, but those of us who have been working with these types of Aggression cases know these facts all too well. 

 Click heading for more details on the study’s findings.


  • Female dogs are more often involved in these aggressive fights than male dogs
  • Only 32% of these incidents involve males while the remaining 62% show females as the aggressor
  • When females get into these fights, injuries tend to be more severe and fights tend to last longer

While Gender is clearly a determining factor in the likelihood of aggressive incidents in the home, it’s also highly predictive of the likelihood of success with Behavioral Training.  Here are some statistics:

  • In Male-Male aggression cases, conflict was reduced in 72% of the cases
  • In Male-Female pairs, conflict reduction occurred in 75% of the cases
  • In Female-Female pairs, while conflict reduction was only 57%…this is still worth making the effort
  • 70% of the time, the instigator of the aggression is the dog most recently brought into the home
  • In 74% of these cases, it ends up being the younger dog that actually starts the fight
  • In 39% of the cases, owners claim surprise stating “they usually get along most of the time!”
  • Some conflicts can be quite serious with 50% resulting in one or both dogs requiring Vet care
  • Overall, 10% of the time the owner is actually injured to the point of requiring medical attention
  • Regardless of past training, dogs were successfully separated using Commands only 8% of the time
  • In 46% of the incidents, it’s the actions of the owner, like paying attention to one dog over the other
  • 31% of the incidents were triggered by simple over-excitement such as an owners arrival at home
  • Resource Guarding was involved in 46% when involving food/treats and 26% when involving toys
  • 41% of involved households had at least 1 dog who had lived in multiple households prior to this
  • When one of the dog in the pair was adopted at 12 weeks or older – fights occurred 39% of the time
  • Dogs adopted from Shelters were involved in 33% of the incidents and 16% for dogs from Pet Store
  • 40% of these dogs will or have shown aggression towards other dogs
  • 27% will or have shown aggression toward humans living in the household
  • 27% will or have shown aggression towards human strangers
  • 20% will or have shown aggression towards their owner(s)
  • 50% of the pairs of dogs involved has at least one member with noticeable Separation Anxiety
  • 30% suffered from and/or exhibited Phobia’s, Fearfulness and other forms of Anxiety

I have been using CBS for over 5 years! I originally sent one of my dogs for in-patient therapy after she began to show increasing aggression to my oldest female after I added a third dog to my pack. She came back a changed dog. Both she and I learned so much! Since then, I have sent ALL of my dogs for some type of training. One for Canine Manners Camp and most recently I sent my newest addition to the Puppy Workshop. I also frequently (5-7 times per year) send my dogs back to CBS when I travel. I trust Brian and his staff completely and know that when my dogs are there, they are not only getting well taken care of they are getting the structure they need. And best of all, they offer transport services back and forth each time. I can't possibly recommend CBS enough for all of your dog needs!

Our American Bulldog Frankie started in the In-patient program at CBS when he was about 8 months old, he was showing signs of aggression towards visitors, as well as our older dog Lexi. Frankie spent several weeks with Brian and his team and he came back to us much improved. With their guidance, we continued to work with him once he returned home. We have sent Frankie back at least once a month for socialization. He always returns to us a more balanced dog every time! Frankie is almost 4 years old now and still loves his visits to CBS. He can’t contain himself as soon as we approach the driveway.

This review is long overdue. We cannot say enough wonderful things about Brian and his pack. Molly Jane attended the in-patient rehabilitation program in June – July 2017. Prior to sending her to Canine Behavioral Services, she had escalating anxiety and dog aggression. We knew that we were reinforcing her behavior towards other dogs as well as her anxiety but were unsure how to break the cycle. Brian and his pack were a life saver. Molly J returned home a more balanced, calm, happy dog and we had a long list of our own behaviors to change. I still smile every time we go on a walk and her tail is up and wagging in excitement again! The other day another dog came bolting up to her off leash and she merely tucked her tail and walked away. I never thought I’d see the day! She even tried to play with a puppy on a hike! Each time we pull onto the street to go for a sleepover, Molly starts whining and crying in excitement. If that is not a testament to what an incredible place Brian runs, I do not know what is. Our friends and family constantly ask what kind of “voodoo” magic Brian and his team practice because of all the pleasant changes they’ve seen in Molly J. She is certainly a new, more balanced, happier dog. Brian saved our relationship with our dog.
