The Question
“I witnessed a dog attack earlier today between two neighbors’ dogs. I didn’t see how it started, but I saw the owner of the attacking dog and the owner of the one being attacked working together to get the attacker off the other one. But it was pretty confronting; they were beating it with sticks, and the dog did not care. He was a big bully breed, and the other was a sheepdog mix-looking thing and old, very harmless-looking; it was so awful. The dog walked away looking shaken up, but no blood, so it appeared like the bigger dog had latched on and then just wasn’t letting go.
I’ve got dogs myself, and I was horrified to see that the dog didn’t listen to the owner when she said stop, and that even two people hitting it didn’t even phase it, as both of my dogs would be scared of me if I said STOP to anything, and they’re both big dogs. Wondering, not that I hope to ever see a situation like this again, but if a dog is ever in ‘attack’ mode, is there any safe and smart way for a person to stop it, other than training their dog in the first place? I’m feeling quite angry about this whole situation on so many levels. It was deeply unsettling. I’m just happy both dogs got out alive and seemingly without life-threatening injuries.” – Mia
Quick Info
Hi Mia,
What you witnessed was genuinely disturbing, and your reaction is completely valid. When a dog enters a sustained attack state, the brain is no longer using the areas responsible for listening, learning, or responding to familiar cues. Instead, the nervous system is flooded with adrenaline, and behavior becomes reflexive rather than thoughtful. I often describe this as an accelerator being pressed to the floor with no access to the brakes. Once that threshold is crossed, verbal commands, pain, or shouting frequently have no effect. This helps explain why the dog did not respond to its owner and why physical blows failed to stop the behavior, even though many dogs would normally retreat under less intense circumstances.
From a safety and animal welfare standpoint, there are very limited options once a fight is in progress, and many well-intentioned actions can actually increase harm. Hitting, grabbing collars, or reaching toward the head commonly results in severe redirected bites to people. Safer approaches focus on distance and protection rather than force. Using a physical barrier such as a trash can lid, chair, large rigid object, or thick item held in front of the body can help block access, interrupt visual fixation, and create separation while keeping human limbs out of the danger zone. This is similar to placing an object between yourself and a moving machine rather than trying to stop it with your hands. Other interventions sometimes discussed include techniques that interrupt balance without placing hands near the mouth, such as lifting the hind end with a leash if someone is trained to do so, or occasionally using water or a sudden environmental interruption, though none of these methods are predictable or truly safe.
It can be helpful to think of events like this as more comparable to a car accident than a moral failure in the moment. Once it happens, control is largely replaced by damage limitation. The fact that both dogs walked away without obvious life-threatening injury is fortunate, but veterinary evaluation for the older dog would still be advisable, as crush injuries and puncture wounds can be hidden beneath intact skin. Feeling shaken and angry after witnessing something like this is a normal response, and your concern reflects thoughtful, responsible guardianship.
Kind regards,
