As temperatures rise, pet owners are increasingly focused on safeguarding their companions’ health during the sweltering summer months. Dogs and cats, covered in fur, have body temperatures 1–2°C higher than humans and lack well-developed sweat glands, making them particularly vulnerable to hot and humid conditions. Here’s what pet owners need to know to ensure their furry friends thrive in the heat.
Maintaining Optimal Indoor Conditions
Many households with dogs or cats rely on air conditioning to keep their pets comfortable. It’s common for owners to leave the AC running even when away from home, concerned about their pets enduring the heat. However, excessively low indoor temperatures or significant indoor-outdoor temperature disparities can lead to health issues, including kennel cough or summer colds. These conditions, often triggered by weakened immunity, manifest as sneezing, nasal discharge, vomiting, or cold paw pads. Young or elderly pets are especially sensitive to such environmental shifts. Experts recommend maintaining an indoor temperature of 25–26°C and ensuring regular ventilation to promote air circulation.

Protecting Skin and Ear Health in Humid Conditions
The onset of the rainy season heightens the risk of skin conditions in pets. High humidity fosters the growth of fungi and bacteria, increasing the likelihood of dermatological issues such as pyoderma, dermatophytosis, or seborrheic dermatitis. Areas with dense fur or skin folds are particularly prone to moisture buildup, elevating the risk of inflammation.
Ear health also demands attention. Pets with floppy ears or excessive ear hair are susceptible to moisture accumulation, which can lead to otitis externa. Signs of ear infections include frequent scratching, discharge, or foul odors. Preventive measures include maintaining indoor humidity between 40–60% and thoroughly drying pets after baths. Regular brushing prevents matting, while consistent skin care minimizes irritation. For ear hygiene, periodic checks are essential. If needed, trim excess ear hair or use a veterinarian-approved ear cleaner. Avoid indiscriminately plucking ear hair, as this can irritate the ear canal and exacerbate inflammation; gentle trimming or professional grooming is preferable.
Preventing Foodborne Illness
Summer heat accelerates food spoilage, raising the risk of foodborne illnesses in pets. Exposed dry food can degrade, leading to gastroenteritis, vomiting, or diarrhea. To mitigate this, purchase smaller food packages for quicker consumption, store them in airtight containers, and keep them in a cool, dry place. Wet food, canned food, or pouches, with their higher moisture content, spoil more rapidly than dry kibble, requiring extra caution. After opening, transfer these to sealed containers, refrigerate, and feed within 1–2 days. Fresh water should also be provided frequently to ensure hydration.
Safe Outdoor Activities for Dogs
While cats typically remain indoors, dogs require outdoor exercise, which demands caution in hot weather. Dogs are at risk of heatstroke, a potentially fatal condition that can cause organ damage due to elevated body temperature. With minimal sweat glands and fur-covered bodies, dogs struggle to dissipate heat, relying on panting to regulate temperature. During walks, signs of distress—such as excessive panting or a protruding tongue—signal the need for immediate hydration and cooling. Additionally, hot pavement can burn paw pads, so consider protective booties or schedule walks for early mornings or evenings, avoiding midday heat. Short, frequent outings are safer than prolonged exposure.
A Season of Vigilance
Summer poses unique challenges for both pets and their owners. By prioritizing proper cooling, hygiene, nutrition, and safe outdoor routines, pet owners can protect their companions from seasonal health risks. These seemingly small steps can make a significant difference in ensuring a healthy, happy summer for dogs and cats.
