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.
