Summer Pet Safety—Hydration and Nutrition Tips for Hot Weather

Summer in Melbourne can bring everything from dry heat to sudden humidity and storm warnings — sometimes all in the same week. While we might reach for a cold drink or turn on the air-conditioning, our pets rely entirely on us to keep them safe, cool and properly nourished.

Here’s what every pet parent should know about hydration and nutrition during hot weather.

Hydration: More Than Just a Full Water Bowl

1. Fresh, Cool Water — Always

Pets can become dehydrated quickly in warm conditions. Make sure:

• Water bowls are topped up at least twice daily

• Water is kept in shaded areas

• Outdoor pets have multiple water stations

• Bowls are cleaned daily to prevent bacteria growth

On very hot days, consider adding a few ice cubes to help keep water cooler for longer.

2. Know the Signs of Dehydration

Seek immediate veterinary attention if you notice:

• Excessive panting

• Dry or sticky gums

• Lethargy

• Sunken eyes

• Loss of appetite

• Reduced skin elasticity (skin doesn’t spring back quickly when gently lifted)

Dehydration can quickly progress to heatstroke — a life-threatening emergency.

3. Wet Food Can Help

For both dogs and cats, incorporating wet food can:

• Increase overall fluid intake

• Support kidney function

• Improve appetite in hot weather

Cats in particular often have a low thirst drive, so wet food can make a meaningful difference.

Nutrition in Hot Weather

1. Appetite Changes Are Common

Just like us, pets may eat less during extreme heat. Mild appetite reduction can be normal — but:

• Complete refusal to eat is not

• Vomiting or diarrhoea alongside reduced appetite needs immediate veterinary attention

If your pet seems off food for more than 24 hours (or sooner in puppies, kittens or seniors), give us a call.

2. Adjust Feeding Times

Feed during the cooler parts of the day:

• Early morning

• Later evening

Avoid large meals in peak heat, as digestion generates body heat and may make your pet uncomfortable.

3. Be Careful with Outdoor Treats

Fresh meats and wet foods spoil quickly in summer temperatures. Discard uneaten food after:

• 20–30 minutes outdoors

• 1 hour indoors without refrigeration

Spoiled food can cause gastrointestinal upset.

Smart Summer Cooling Strategies

• Provide shaded areas outdoors at all times

• Use cooling mats or damp towels

• Never rely on a kennel or dog house alone — they can trap heat

• Avoid exercise during the hottest part of the day

• Never leave pets in parked cars (even briefly)

Special Risk Groups

Some pets are particularly vulnerable to dehydration and heat stress:

• Brachycephalic breeds (e.g., French Bulldog, Pug, British Bulldog)

• Senior pets

• Overweight animals

• Pets with heart or respiratory disease

• Very young puppies and kittens

If your pet falls into one of these categories, take extra precautions during hot weather.

Heatstroke Is an Emergency

Signs of heatstroke include:

• Rapid or distressed breathing

• Collapse

• Vomiting

• Bright red gums

• Disorientation

This is a medical emergency. Begin cooling (with cool — not ice-cold — water) and seek veterinary care immediately.

Final Thoughts

Melbourne summers can be unpredictable, but one thing remains constant: prevention is always easier than treatment. Small adjustments to your pet’s hydration, feeding routine and environment can make a big difference to their comfort and safety.
