5 Kinds of Dog Aggression: #GetTough on Dog Fighting

by | May 14, 2025 | Dog Training & Care | 27 comments

April 8th was DOG FIGHTING AWARENESS DAY, and I’ve written about dog aggression and stopping dog fights before. It’s a good time to review the 5 common kinds of dog aggression and what to do.

According to the ASPCA, dog fighting happens all over the country and in all kinds of communities–rich, poor, middle class, it doesn’t matter, it’s there festering just beneath the surface. When fight rings are located, cases are built, offenders are prosecuted, and abuse survivors find loving homes.

The ASPCA educates as many folks as possible about this cruel sport. Yep, can you believe it? it’s considered a SPORT by fight proponents. #GetTough on Dog Fighting campaign offers free information and ways for all animal lovers to get involved.

DOG FIGHTS AFFECT ALL PETS & PEOPLE

Hey, a dog fight issue doesn’t affect just about one breed. It impacts ALL dog owners–and cat lovers, too, because dogs are trained to fight by “practicing” on other animal victims.

Spectators even bring kids to the fights to introduce them to the sport. *wiping eyes* The thought makes me weep with anger. That’s why my 3rd pet-centric thriller SHOW AND TELL shines a light on this dirty practice (and for once, the bad guys get appropriate justice!).

While breed bans might suggest that “dog aggressive breeds” are at the heart of this issue, let’s get real here. All dogs, even the one snoozing on your lap, may from time to time act in an aggressive manner. The fight industry exploits and perverts canine behavior for its own ends. Still, it’s important for all dog lovers and even those who do NOT have dogs, to understand what’s going on with “aggression.”

5 Kinds of Dog Aggression

Here’s the deal. Aggression is a NORMAL part of being a dog, and while dog-on-dog aggression is more prevalent in some breeds, ALL dogs have the potential to fight and bite. Aggression can arise out of pain or health issues. Growly dogs believe they have a good reason to aggress (they often do!) whether owners agree or not.

Aggression can be complicated and require professional help, but here’s how to recognize 5 common types and learn how to keep the peace.

dog fight

Play Aggression looks scary but dogs tell each other it’s just pretend by using gestures like the play bow (butt up, front down). Puppies learn to inhibit bites when they play with other dogs, and owners also can teach limits.

If the mouthing hurts, YELP like another puppy. Whimper and say, “You hurt me.” Immediately after you yelp, give the dog a 10-minute time out—no mouthing allowed—to teach him that hard bites make the fun stop.

Predatory Aggression includes stalking, chasing, catching and biting like in play, but predatory dogs won’t play bow—they’re deadly serious. Joggers, bicyclist, and moving cars and cries of young children, babies and smaller pets can trigger prey drive.

Predatory behavior may go away as the youngster grows up, but keep targets safe with strict supervision. Identify triggers (like joggers) and avoid them. Teach dogs to control natural impulses with obedience drills. A “happy” word the dog can’t resist (ball, cookie, ride) can often change the dog’s attitude and interrupts the behavior.

dog fear

Fear Aggression results when a dog can’t escape a scary situation. Caged, chained or cornered dogs often bite out of fear. Snarls, growls or bites make the scary “thing” go away, which rewards the dog so she’ll repeat the behavior. Reaching for the scared dog’s collar almost always prompts a bite, because a hand descending toward the head looks threatening.

Dogs may be fearful of strangers. And if you wear a hat, your dog may not recognize you! Learn about dogs hating hats in this post.

Avoid petting on the top of the head. Instead, pet the dog’s sides or chest. Don’t stare, which can intensify intimidation. Play builds confidence, so teach “fetch” while avoiding tug-games that can encourage fear-biting behavior. Use pheromone therapy such as Comfort Zone with DAP to help calm fears.

Territorial aggression typically involves herding and protection breeds. Dogs bark, lunge and growl at the fence or doorway, and are rewarded when the mailman, new dog, or your fiancé goes away. Conspire with visitors so the outcome changes.

Have the mailman toss treats to the dog, but without making eye contact or saying anything. Once the dog quiets to munch the treat, the mailman can say, “Good Rex!” and walk away. He should NOT walk away as long as the dog barks and lunges. If Rex ignores the treat and continues to bark and lunge, then YOU call the dog and reward him with a treat or toy for coming. The mailman leaves as the dog retreats—so essentially neither won.

Guarding Food, Toys, Furniture are all part of dominance aggression. These dogs often object to being restrained—as for nail trims—and the aggression can gets worse with punishment or confrontation. They’re often young intact male dogs who want to call the shots with people, but then tremble or seem to act “remorseful” afterwards. An argument over toys or mealtime that prompts a first instinctive snarl teaches the dog that aggression keeps others a safe distance from important resources.

Dominance aggression can be complicated and dangerous to solve and usually requires a professional. Neutering the dog and managing resources can help. If the dog protects toys, remove them so he has nothing to guard. Require the dog to “earn” privileges by paying with good behavior. For instance, ask him to “sit” (he sits), which earns him what he wants (attention/food bowl/open door/verbal praise). He should get NOTHING unless he earns it by responding in a positive way to your command.

    Excellent tips! Dog fighting is a very common affair in almost all county in the world. Dogs love fighting. Once they get a chance to fight, never miss that. Play Aggression is quite common in almost every dog breed. I like this aggression though some guys don’t like it at all. Thanks Amy very exceptional post with nice images. I have learn some new things from your post. Very informative! But you can go more dipper.

    Yes, mostly these kind of aggression are seeing in dog fight and that is dangerous also. However, with proper training, we can reduce it. Pet trainers are teaching them how to behave and visit with new ones.

    When I was walking to school one morning in the 1980s, a man and his dog came out of the house. While he was locking the door, the dog jumped up to say hi to me and scratched me. Which kind of aggression would you consider that, or is it just a case of a dog forgetting he’s not a cat (and as such cannot put his claws away)?

      Actually, based on your description (jumping up to say “hi”) I would consider that a submissive signal. *s* Dogs show their deference to other dogs and to people by aiming licking at the face/mouth/eye area, and so often jump up to reach us. People get aggravated, yell, etc which tells the dog, “Oh, I need to be even MORE submissive, I’ll jump up even more!…” *s*

      Dogs can be taught to greet/show deference in other ways but they do need to be taught. Great question!

    TY for the info, Amy . I know even the sweetest of dogs can get angry and we know Dexter does not like a dog messing with him if he is eating a bone.

    This is a great post – valuable information. Henry and Reese (and Ricky) change roles regularly and we joke about who is king or queen of the castle. Joking aside, this is a serious matter. Thanks for sharing!

      Hi Sadie, well adjusted pets DO change roles, especially in play. Often the one “in charge” will take the subordinate role during play to entice others to engage in the game. Then once it’s over, the established roles resume.

    Thanks for this explanation. I knew there were different types (just like they are for humans), but this is really helpful in understanding, preventing, and handling aggression.

    It is very interesting to learn about the different types of aggression in dogs. They are similar to the ones in cats. I think it is important that pet owners become aware of these and learn to tell the difference so they can properly communicate with their pets.

      Absolutely Robin, and they are similar for cats. Guess I need to do one for our kitty friends, too!

    It’s important to make these distinctions. I am the marketing director for a dog boarding facility and although I work from home, I still went through all of the training about how to differentiate between types of aggression. It’s proven to be helpful even at the dog park!

      Very true, Amanda! It’s very important for dog owners, but equally important for PARENTS of young kids that encounter other people’s dogs.

BITE Prevention for Halloween: 9 Ways to Keep Fangs At Bay

This is a timely subject so I try to revisit the information every year. I write about this every year because it’s so darned important. With Halloween in the offing, this is the perfect time to brush up on dog safety issues and protect your kids, too.

To give equal time, there are many kitty-centric Halloween myth-teries you’ll find fascinating, especially about black cats.

While nonstop doorbell rings and visitors showering attention may be doggy bliss for your pet, even friendly laid back pooches get their tails in a twist over the disruption to routine. That can be dangerous for the pet—and for the human. Learn more about dog bites and kid safety here…

Black Cat Appreciation Day & Halloween Black Cats

August 17 is Black Cat Appreciation Day to counter the Halloween black cat negative myths. Of course, those folks who share their lives (and pillows!) with a special black cat know better. Sadly, too many black cats remain in shelters rather than being adopted.

In fact, some evidence supports the notion that black cats (one of the first “mutations” of wild coat color), enhanced what I call the feline friendly factor. Black cats often seem to be much more agreeable and love spending time with their chosen human. Maybe that’s why so many of the so-called witches were associated with black kitties.

People have more difficulty picking cats because they assume all felines are the same. And because usually, cats pick us.

Halloween Pet Costumes: How to Dress Dogs in Costumes

Do you enjoy dressing up the house—and yourself—for the holidays? If you want to include Halloween pet costumes, start now to get them used to the notion. Most of the costumes don’t fit Bravo-Dawg, and I’ve not yet tried Shadow-Pup. I’ll share pictures if/when that happens.

Meanwhile, be sure to keep pets safe over Halloween, though. Dogs and cats aren’t always fans of wearing Halloween costumes, but with these tips, you can help pets accept the notion.

Halloween Pet Costumes

Some pets enjoy dressing up, particularly the small dogs already used to wearing coats and sweaters in cool weather. There are many pet costumes available from pet products stores, from fancy to plain. If your outgoing, confident pet is willing, you can have great fun with costumes. But if your pets don’t care for dress up, don’t press it. Many pets may bite over Halloween out of fear of change.

Even reluctant pets may be persuaded to wear a fancy collar or bandana or painted toenails.
