Multi-dog household: when your dogs train each other

Two or more dogs feeding off each other can lock in the wrong defaults faster than you can train the right ones.

In a multi-dog home, arousal is contagious. One dog barks, the other joins. One reacts at the window, both rehearse it. The dogs are training each other, and a single shared routine often suits none of them.

The work starts with structure that each dog gets individually: real one-on-one play with a human, separate CALM so neither relies on the other to settle, and modes that hold regardless of what the other dog is doing.

Once each dog can regulate on their own, the household stops amplifying itself and the dogs can actually be together calmly.

Try this week. For a week, give each dog ten minutes of one-on-one time a day, away from the other, doing focused play or quiet settling. Dogs who only ever exist as a pair often have no idea how to be calm alone.

Case notes

From a real session: who had room to move away

Two dogs, an adolescent female and an older male, plus a cat. The owners had a fight to report. She was tethered for dinner, he drifted over, she went for his face, he went back at her, and the owners pulled her away and comforted him. They asked me what they should have done to her.

Nothing to her. In that situation I would have corrected him. He had the room to move away and he chose to come and stand in her space. If I am behind a fence and you walk up and poke me, and I go hey, stop that, and then you fight me, well, you had the chance to leave. The tethered dog cannot. She was not advocated for. So the rule is: when a fight happens, look at who had room to move, and never pull the tied dog, because that feeds the arousal you are trying to drop.

Then we looked at the good days, because the owners said the two dogs played nicely most of the time and she was always the issue. I do not ask whether play is rough. I ask whether it is reciprocal. Did he want it? When he stopped, stood still and looked at the humans, he was asking a question: are you going to do something about this? If nobody does, he learns he has to fight her himself. My job was two jobs at once: teach her not to be a pest, and advocate for him, which is an indoor line on her and his freedom to walk away.

The quieter problem was him. He lived on a lap, leaned, stared, pat me, pat me. Controlling in a cuter way, but it is the same. The owners are the biggest resource in that house, and I do not want the dogs competing for it. Patting became one dog at a time, the other moved off. None of your business.

The incidents they never saw coming had started twenty seconds earlier. Her body stiff, head lowered, going still and quiet. She was planning. His version was a motionless stare, feet not moving, brain challenging, and she read it before they did. Once the owners could see that, the fear in the house dropped, because they were no longer reacting to fights, they were moving intention away before it landed. She had two weeks of cycles first. His program started that day. I was not fixing a problem. I was solving the dynamics between them.

Questions

Frequently asked

Should I train my dogs together or separately?

Separately first, for the foundations. Each dog needs to learn the modes without leaning on the other. They come back together once each can hold their own.

  • The why behind the method

    Her patience, deep knowledge, and structured approach made all the difference in training our puppy, Bagel. Diona explained everything in detail, ensuring we understood not just the how but also the why behind dog training. Her guidance gave us the confidence to understand our puppy's needs.

  • A dog whose needs are met

    Diona didn't just teach us how to train our heeler/staffy pup, she taught us how to understand him, how to satisfy him, teach him, play with him and calm him, and therefore how to truly befriend him. Thanks to Diona we got our nights and sanity back, and learned how to truly bond with our pup.

  • Cycles and the four modes

    She is like no other trainer and really helps you understand the cycle of reactivity and taps into the cycles of what we need to do to help you achieve a calm dog that focuses on you. Following her training cycles helps our two dachshunds so much. If you keep it up consistently the results will come.
