Tetanus in Dogs: Welfare and Prevention

Welfare guide to tetanus in dogs -- a serious, preventable disease causing extreme muscle rigidity and suffering.

Key Facts

Tetanus in dogs is caused by Clostridium tetani toxin entering through wound contamination
Dogs are relatively resistant to tetanus compared to horses -- but the disease is still severe and often fatal
Clinical signs include progressive muscle rigidity, lockjaw, erect ears, and a sardonic grin expression
Affected dogs become progressively unable to swallow, open their mouths, or walk
Welfare deterioration is severe -- affected dogs are conscious throughout the painful spastic paralysis
Treatment is prolonged -- weeks of intensive nursing care in a quiet low-stimulation environment
Prevention includes wound management and cleaning after any puncture or bite wound
Unlike horses, routine tetanus vaccination is not standard in dogs in the UK -- but should be considered for working or farm dogs

Welfare Significance

Tetanus in dogs causes extreme suffering -- the muscle spasms and rigidity are painful and progressive, and the dog remains conscious and aware throughout. The disease is preventable through appropriate wound care and vaccination. Any dog with a puncture wound should have the wound thoroughly cleaned and veterinary advice sought immediately.

What You Can Do

Seek veterinary assessment and thorough wound cleaning for all puncture wounds in dogs
Consider tetanus vaccination for working or farm dogs at high risk of wound contamination
Ensure any dog with tetanus is treated in a quiet dark environment to minimise stimulation-triggered spasms
Maintain intensive nursing care throughout recovery -- this is a welfare-intensive disease
