Correct and complete diagnosis and successful treatment requires collaboration across specialties; medicine, anaesthesia...
Article
Nonspecific performance and rideability issues are more likely a manifestation of pain in the ridden horse rather than a true behavioural problem. A systematic and thorough investigation focusing on the potential presence of pain‐related conditions is thus crucial in horses with such complaints. It can, however, be challenging to determine whether...
