Animals pushed to their limits: what are the implications for welfare?

Summary

# Editorial Summary: Animals Pushed to Their Limits: What Are the Implications for Welfare? As performance demands on horses and other working animals continue to intensify, the question of where the biological threshold lies between optimal performance and compromised welfare has become increasingly pressing for equine professionals. A multidisciplinary discussion convened jointly by CABI and the Royal Veterinary College examined the physiological and welfare consequences of pushing animals towards their performance limits across various species, including horses, dairy cattle and dogs. The findings highlight that whilst selective breeding and training can enhance athletic capacity, there exists a point beyond which further demands result in measurable deterioration in health markers—including increased injury rates, impaired immune function, metabolic dysfunction and behavioural abnormalities. For farriers, veterinarians, physiotherapists and coaches, this underscores the importance of individually assessing each animal's genuine biological capacity rather than applying standardised intensity protocols, monitoring for subtle early warning signs of systemic stress, and recognising that short-term performance gains achieved through excessive conditioning often exact long-term welfare costs. The practical implication is clear: sustainable high performance requires working within an animal's sustainable limits rather than continually extending them.

Key Findings

• •Animals across multiple species (horses, cattle, dogs) are being pushed to biological limits in work and production
• •Current practices risk compromising health and welfare when biological limits are exceeded
• •Need for evidence-based discussion on acceptable boundaries for animal use
