If you read the paper [1] I wouldn't say the data is convincing. The author's openly admit to changing the methodology of the data analysis (p-hacking) after the data collection.
There are issues with data collection. Some data collectors measured to the nearest 5 degrees and some to the nearest 10 degrees.
There are issues with statistics. Rao's circular uniformity test values are presented without any commentary or analysis of there significance.
The rate of change of magnetic declination is presented as a percentage whereas it is actually in minutes of arc per minute (of time) which would have SI units of s^-1.
It is still unclear how rate of change of magnetic declination relates to how a dog chooses to orient itself. I suspect it has something to do with a correlation between rate of change of magnetic declination and time of day. But why time of day is correlated with orientation seems to be an unknown. Maybe walks at a particular time of day or position of the sun.
The authors dismiss the position of the sun as being an influencing factor but present very little data to support this conclusion.
