Common Summer Diseases and Symptoms in Cats and Dogs
Hong Kong summers are hot and rainy, and pets, with their high activity levels and frequent outdoor activities or contact with other animals, are prone to health problems. Here are 5 common pet diseases and symptoms that owners should be aware of:
- Heatstroke (heat exhaustion)
Causes: High temperature, high humidity, poor ventilation, strenuous exercise, and prolonged stay in the vehicle compartment, etc.
symptom:- Excessive breathing, drooling
- Vomiting, diarrhea, unsteady gait
- Coma, epilepsy, dilated pupils
- A cat breathing with its mouth open is a dangerous warning sign.
- Ectopic infections (such as fleas and ticks)
Causes: Summer is the peak breeding season for parasites. Increased outdoor activity for pets increases the chances of parasites jumping onto their bodies and multiplying.
symptom:- Scratching, hair loss, and red, swollen skin
- Scabbing, anemia (in severe cases)
- Skin diseases (eczema, fungal infections, allergies)
Causes: damp and hot weather, wet hair, allergens, flea bites, etc.
symptom:- Itching, rashes, hair loss, and skin odor
- Fungal infections can cause circular hair loss and dandruff.
- Dehydration and electrolyte imbalance
Causes: Insufficient water intake, excessive breathing, vomiting, or diarrhea.
symptom:- lethargy, decreased skin elasticity
- Sunken eyes, loss of appetite
- Gastrointestinal discomfort (from spoiled or cold food)
Causes: Food spoilage, eating cold or unclean food.

Which pet checkups can detect summer diseases early?
When should owners consider taking their pets for a checkup?
