Bad dog introductions cause most dog-dog aggression problems. A controlled, calm introduction sets the tone for the entire relationship.
The Parallel Walk Method
This is the safest way to introduce two dogs:
- Both dogs on leash, one handler each. Start 20+ feet apart, walking in the same direction.
- Walk parallel for 5-10 minutes. Reward calm behavior with treats.
- Gradually decrease the distance between dogs if both are relaxed.
- When they can walk side-by-side calmly, allow brief butt-sniffing (3 seconds max).
- Call them away and reward. Repeat.
- Only allow free interaction in a fenced area once both dogs are calm and showing relaxed body language.
Red Flags During Introductions
- Stiff body, hard stare, raised hackles → increase distance immediately
- One dog pinning the other repeatedly → separate and try again another day
- T-posing (standing over the other dog's shoulders) → redirect before it escalates
- Intense fixation on the other dog → too close, needs more parallel walking
Never:
Never introduce dogs face-to-face on tight leashes. Leash tension creates reactivity. The parallel walk prevents this by keeping both dogs moving and relaxed.
