At a glancePlan work, shade, water and transport before hot conditions develop; suspected heatstroke needs urgent veterinary help.WORKING DOG reference library · Added 2026-10-19 · Expert review pendingThis educational guide has not been reviewed by a veterinary professional. Discuss decisions about your dog’s health or diet with your veterinarian.Change the work planRSPCA recommends avoiding exercise in extreme heat and providing cool, shaded, ventilated surroundings. Assess the actual site and schedule, including waiting time at trials and time inside vehicles.Assign responsibilityBefore starting, decide who checks dogs, where they can rest and who can stop the activity. Keep the nearest veterinary contact and route accessible to everyone involved.Respond earlyIf you suspect heatstroke, contact a veterinarian immediately and follow their instructions. Do not wait for the next scheduled break or use a breed’s reputation for toughness as reassurance.Brief replacement staff and visitors on the same stop-work and contact arrangements. Check that the resting area remains suitable as sun and shade move during the day, including while the handler is occupied.Make the plan cover loading, queuing and the journey home. A cool morning start does not establish that conditions will remain suitable through the whole day.Recognise the change from normalRSPCA lists signs of possible heatstroke including persistent panting, weakness, altered coordination, vomiting and collapse. These signs are not a home diagnostic checklist or a reason to wait until every sign appears. A dog becoming unwilling to move or behaving abnormally during heat needs the activity stopped and urgent veterinary guidance. Explain to relief handlers what is normal for the individual and which changes should prompt immediate action. Include dogs waiting in transport equipment in the same monitoring plan, because active work is only part of the day’s heat exposure.Common questionsShould I wait for collapse before seeking help?No. Suspected heatstroke needs urgent veterinary help. Abnormal panting, weakness or behaviour during heat should not be dismissed because the dog is still standing.Sources & further readingReferences for this guide.
