Reinforce the good – replace the unwanted.
Differential Reinforcement (DRI/DRA)
Differential Reinforcement is a behaviour strategy that reduces unwanted behaviours by reinforcing alternative ones. In dog training, the two common types are DRI (Differential Reinforcement of Incompatible behaviour) and DRA (Differential Reinforcement of Alternative behaviour).
With DRI, the trainer rewards a behaviour that cannot happen at the same time as the unwanted one. For example, a dog cannot jump up if it is sitting. With DRA, the trainer rewards an alternative behaviour that serves a similar function, such as teaching a dog to fetch a toy instead of chewing furniture.
By shaping choices toward better options, differential reinforcement creates clarity and builds habits that naturally replace problematic actions.
Core benefits of DRI/DRA include:
- Reducing unwanted behaviours without punishment
- Encouraging positive, functional alternatives
- Building self-control and consistent habits
- Strengthening the dog–owner bond through cooperation
Differential reinforcement transforms problems into opportunities – every misbehaviour becomes a chance to reward something better.
Differential Reinforcement (DRI/DRA) – FAQ
DRI reinforces a behaviour that is physically incompatible with the unwanted one (e.g., sitting instead of jumping). DRA reinforces an alternative that serves the same purpose (e.g., chewing a toy instead of furniture).
Because it teaches the dog what to do instead, rather than only what not to do. This creates lasting learning and a more positive relationship.
Yes. For example, teaching a dog to focus on the handler (alternative behaviour) instead of lunging at another dog can reduce reactivity over time.
Not always. While food is a strong reinforcer, play, praise, or access to favourite activities can also serve as powerful rewards.
Consistency is key. Many dogs begin to show improvement within days, but lasting behaviour change usually develops over weeks of practice.
