Dog on Dog Aggression

The Reality vs. The Dream
You’ve finally got a dog, after years of dreaming of having a four-legged companion for group walks, trips to the beach, dog shows, and an extended social life. But what if your dog doesn’t like other dogs? Instead of the social life you imagined, you might find people avoiding you and giving you dirty looks as your dog barks at theirs, with whispers of “There are no bad dogs, only bad owners.”

My Experience
I have been training dogs for 8 years, am a member of the APDT, and specialize in dog-on-dog aggression. It is one of the most common issues I deal with and a subject I also present seminars on.

Causes of Dog on Dog Aggression
Dog on dog aggression can be caused by many factors, some of which are entirely out of the owner’s control. Here are some common causes:

Diet
Many popular dog foods contain e-numbers and colorings that can affect behavior and fuel aggression. Check your dog food. Is it colorful? Choose a dog food with a high percentage of a named meat source.

Genetics
What were your dog’s parents’ temperaments? Nervousness or aggression can be passed down to your dog.

Pain and Illness
Aggression or behavior changes should always prompt a trip to the vet. Pain isn’t always obvious, and many aggressive dogs have underlying health issues like hip dysplasia, elbow dysplasia, ear infections, stomach issues, bladder issues, and musculoskeletal problems. I highly recommend a referral to a body worker such as a Canine Massage Therapist or Chiropractor.

Fear
Fear can stem from a lack of socialization or a bad experience. Has your dog been attacked or bullied by an overzealous dog?

Aversive Training Techniques
Has your dog been punished around other dogs? Is your dog wearing a choke chain or other uncomfortable equipment that associates seeing other dogs with something unpleasant?

Solutions
Understanding the underlying causes of dog-on-dog aggression is the first step toward addressing it. Here are some actions you can take:

Evaluate and Improve Diet: Switch to a dog food with natural ingredients and a high percentage of named meat sources.
Consult a Veterinarian: Ensure your dog is free from pain and illness that could be causing aggressive behavior.
Seek Professional Help: Consider working with a canine body worker to identify and treat any physical discomfort.
Build Positive Associations: Use positive reinforcement techniques to create pleasant experiences around other dogs.
Avoid Aversive Methods: Replace choke chains and other punitive tools with comfortable, positive training equipment.
Addressing dog-on-dog aggression takes time, patience, and understanding, but with the right approach, you can help your dog become more comfortable and sociable around other dogs.
