Although Donkeys originated in arid, desert climates, Domestic donkeys can succumb to heat stress and dehydration just as fast as any other animal when temperatures spike.
Donkeys can drink up to 10% of their body weight in water each day during hot spells. Keep fresh, clean water in the shade so the water stays cool and refreshing to encourage drinking.
If they aren't drinking enough, adding a splash (for a 5-gal. bucket, 1-2 Tbsp; for a 50-gal. tank, 1 cup) of apple juice can coax donkeys to the trough.
Add a donkey-safe electrolyte supplement or trace mineral salt block too, to replace what they lose through sweat.
Steer clear of low, tin-roofed buildings, as they turn into ovens in direct sunlight. If you offer stalls for your donkeys, be sure to secure electric fans safely out of reach, keep the air moving, and chase off biting insects.
Donkeys with light coats or pink skin sunburn easily. Dab pet-safe sunblock on exposed, sensitive spots like their muzzles and the tips of their ears.
Brushing out the leftover winter coat daily lets skin breathe and helps them cool down faster.
Freeze a tub of water with carrots, cucumber, or apple slices inside. It's enrichment and a portable cool-down all in one.
Hose them off gently by starting at the legs and chest and working up. Be sure ALWAYS to let the hose run a minute first so you're not blasting sun-baked, scalding water from the line on them.
Save riding, training, or farm work for the cooler hours early in the morning or late in the evening, never in extreme heat.
Donkeys are stoic — they hide pain and discomfort until they're seriously unwell. Call your vet immediately if you see:
• Heavy, rapid, or labored breathing
• Flared nostrils
• Lethargy
• Unusual sweating (especially neck and base of ears)
• Loss of appetite
They could be suffering heat stress.
While waiting for the vet, wrap ice packs or frozen water bottles in towels and place them in the armpits and groin to help bring their core temperature down quickly.
Stay cool out there, and keep an eye on your long-eared friends.
