Keeping Pets Safe in Hot Weather: The Complete Summer Safety Guide for Dogs, Cats, Rabbits, Horses and Small Pets

Warm weather can be lovely for people, but it can quickly become dangerous for animals.

Dogs, cats, rabbits, horses and small pets can all struggle in high temperatures, especially if they cannot get away from the heat, access fresh water or cool themselves properly.

At East Limerick Vets, we want to help owners recognise the risks early and keep their animals safe during warmer weather.

Understanding heatstroke

Heatstroke is a serious veterinary emergency. It happens when an animal’s body temperature rises to a dangerous level and they can no longer cool themselves effectively. Without prompt veterinary care, heatstroke can cause organ damage and, in severe cases, can be fatal.

It does not only happen during heatwaves. Pets can overheat during exercise, travel, play or time spent in hot, poorly ventilated spaces.

Which pets are most at risk?

Any animal can overheat, but extra care should be taken with:

• Flat-faced breeds such as Bulldogs, Pugs, French Bulldogs and Persian cats.

• Older pets.

• Puppies and kittens.

• Overweight animals.

• Pets with heart or breathing conditions.

• Thick-coated breeds.

• Rabbits, guinea pigs and other small pets kept outdoors.

• Horses exercising or travelling in warm weather.

  
  

Never leave pets in parked vehicles

Even on a mild day, the temperature inside a parked vehicle can rise rapidly.

Leaving windows slightly open or parking in the shade does not remove the risk.

The same concern applies to caravans, conservatories, greenhouses, poorly ventilated sheds and enclosed trailers.

Walk dogs during cooler parts of the day

Choose early morning or late evening walks when temperatures are lower.

Avoid strenuous exercise during the hottest part of the day. If your dog slows down, seeks shade, lies down or pants heavily, stop and allow them to cool.

Check pavements before walking. If the surface feels too hot for the back of your hand after a few seconds, it may be too hot for your dog’s paws.

Provide water, shade and airflow

All pets should have access to fresh drinking water.

During warm weather:

• Refill water bowls regularly.

• Provide shade at all times.

• Keep indoor areas well ventilated.

• Let pets rest during the hottest part of the day.

• Use cooling mats or shallow paddling pools where appropriate and supervised.

  
  

Rabbits and small pets need extra care

Rabbits and guinea pigs can overheat quickly.

Outdoor hutches should never be left in direct sunlight. Make sure they have shade, airflow and fresh water.

Frozen water bottles wrapped in towels, ceramic tiles and cooler indoor spaces can help during very warm weather.

Horses and farm animals

Horses and livestock also need careful management during warm weather.

Make sure they have constant access to clean water, shade where possible, good ventilation and regular monitoring.

Exercise and travel should be planned for cooler parts of the day where possible.

Other summer hazards

Warm weather can bring other risks too such as:

Blue-green algae: Do not allow dogs to swim in or drink from water that looks green, blue-green or has surface scum.

Grass seeds: Check paws, ears and coats after walks through long grass.

Parasites: Fleas and ticks are more active during warmer months. Ask your vet about appropriate parasite prevention.

Barbecues: Keep pets away from cooked bones, corn cobs, onions, grapes, raisins, chocolate, alcohol and foods containing xylitol.

Sunburn: White cats and pets with pale noses, ears or thin coats may be more vulnerable to sun damage.

Signs of heatstroke

Seek urgent veterinary advice if your pet shows signs such as:

• Heavy or excessive panting.

• Drooling more than usual.

• Difficulty breathing.

• Weakness or lethargy.

• Vomiting or diarrhoea.

• Confusion or disorientation.

• Collapse.

  
  

What should you do if you suspect heatstroke?

If you think your pet may be suffering from heatstroke:

• Move them immediately to a cool, shaded and well-ventilated area.

  
  

• Begin cooling them straight away using cold tap water. You can pour water over their body or use towels soaked in cold water while ensuring air can circulate around them. Avoid covering the animal completely with wet towels, as this can trap heat.

  
  

• Contact your veterinary practice immediately to let them know you are on your way.

  
  

• Continue cooling your pet during transport to the veterinary practice.

  
  

• If your pet is conscious and able to drink, you may offer small amounts of cool water, but do not force them to drink.

  
  

Heatstroke is a veterinary emergency. Even if your pet appears to recover, they should be examined by a veterinary surgeon as complications can develop after the initial episode.

Prevention is always better than cure

Most heat-related emergencies can be reduced with simple precautions.

Walk dogs during cooler hours, provide fresh water and shade, avoid hot cars and poorly ventilated spaces, and watch carefully for early signs of overheating.
