Turning preference in dogs: North attracts while south repels.

Area of Science:

• Animal Behavior
• Magnetoreception
• Sensory Ecology

Background:

• Dogs display individually consistent turning preferences when choosing between two food dishes.
• A previously observed
• pull of the north
• phenomenon showed directional bias influenced by the north.
• This bias occurred even without outdoor environmental cues.

Purpose of the Study:

• To replicate and investigate the
• pull of the north
• phenomenon in dogs under controlled indoor magnetic conditions.
• To determine if magnetic north or topographic north influences canine turning preference.
• To explore the relationship between turning preference, magnetic fields, and potential sensory mechanisms.

Main Methods:

• Experiments were conducted indoors using magnetic coils to manipulate the magnetic field.
• Dogs were tested under natural magnetic conditions and with a magnetic field shifted 90° clockwise.
• Turning preferences were analyzed in relation to dish placement (N, S, E, W) and magnetic field orientation.
• Motoric paw laterality (Kong test) and dominant eye were assessed.

Main Results:

• The
• pull of the north
• was confirmed indoors, demonstrating the effect of magnetic north.
• A
• repulsion of the south
• effect was also identified, with south-placed dishes being less frequently chosen.
• Turning preference correlated with dominant eye laterality, not paw preference.
• Right-dominant eyes were associated with clockwise turning, and left-dominant eyes with counterclockwise turning.

Conclusions:

• Canine turning preference is significantly influenced by the Earth's magnetic field, specifically magnetic north.
• The observed directional bias is likely mediated by magnetoreception, potentially involving a conflict between visual guidance (dominant eye) and magnetic sensing.
• The findings suggest a complex interplay between visual perception, motor control, and magnetic field detection in dogs.
