The second encounter can change the result
A first response and a response after experience answer different questions. In a 2026 follow-up, researchers re-tested dogs from an earlier hand-touch study. The result adds a time dimension to the story. It does not say that practice improves every ability or that a dog's general intelligence increased.

A follow-up, not a fresh independent sample
The later study included 105 dogs from the original group of 111 first-test completers. It used two testing occasions about thirty days apart. When reading the two publications together, do not count them as independent groups that happened to produce related findings. The shared participants are part of the comparison.

Name the component that changed
Average reversal-learning performance improved across the two occasions. Comparable overall improvement was not found for every measured component. The authors also did not find significant differences among clades in the magnitude of performance change. Improvement within some groups and a difference in improvement between groups are separate statistical questions.

Experience is not fully controlled
The authors could not rule out owner-mediated practice between sessions. Consecutive phases, fatigue, learning history, only two testing occasions and small clade samples also limit interpretation. Those limits prevent a clean claim that a particular amount of household practice caused a broad cognitive gain. We offer no practice schedule or reward-withholding experiment.

Leave room for a different next result
The follow-up shows why an initial task profile need not remain unchanged on re-exposure. It does not make every initial difference false, and a difference becoming non-significant does not prove exact equality. Ask which response was measured, when, and after what experience. Keep those answers beside any statement about learning.
