Summary
# Editorial Summary Predator species, particularly wolves, have increasingly returned to European farming landscapes and caused significant livestock losses, prompting some German farmers to adopt guard dogs as a protective strategy—a practice that has generated public concern due to unfamiliarity with such management methods. Researchers observed the behaviour of 113 guard dogs across German farms with regular public access, using both direct field observation of dog proximity and behaviour towards goats and horses, alongside structured reports from trained observers documenting interactions with various livestock species and people. Key findings revealed that guard dogs maintained close positioning (within one body length) to their charges, demonstrated friendly behaviour towards farm owners and familiar personnel whilst remaining dominant and watchful towards strangers and unfamiliar dogs, and successfully adapted to protecting multiple species simultaneously. The study indicated that older dogs and larger mixed-sex groups consistently showed the most reliable protective vigilance whilst maintaining appropriate friendliness with known farm personnel, suggesting that deliberate training and socialisation protocols were effective. For practitioners working with farms employing guard dogs, these findings validate that well-managed guard dog systems can function effectively across diverse livestock enterprises without necessarily compromising safety for legitimate farm visitors, though the importance of ongoing management and training to maintain appropriate behavioural responses cannot be overstated.

Practical Takeaways
- •Guard dogs can be effectively trained to protect horses alongside other livestock species and coexist safely with farm personnel and regular visitors.
- •Older dogs and mixed-sex groups show superior performance for farm protection tasks; investment in proper training and socialisation yields consistent results.
- •Guard dogs adapt well to working environments with public access, suggesting feasibility for farms balancing predator protection with community relations.
Key Findings
- •Guard dogs maintained proximity within 1 body length of goats and horses, demonstrating effective protective positioning.
- •Dogs displayed friendly behaviour towards farm owners and known persons while remaining dominant and watchful towards unfamiliar persons.
- •Older dogs and large mixed-sex guard dog groups were consistently more watchful against external individuals while remaining friendly to farm personnel.
- •Guard dogs successfully adapted to protecting multiple livestock species through appropriate farmer training and socialisation.
