Have you ever noticed how your dog’s mood changes with the seasons? Whether it’s spring, summer, autumn, or winter, each season affects your dog’s mood to varying degrees—just like it does for humans.
Hot Weather
In hot weather, most dogs tend to become sluggish. During the peak of summer, many dogs prefer staying indoors with the air conditioner on, rather than playing outside.
It’s important to note that brachycephalic (short-nosed) dogs are especially vulnerable in summer, and unfortunately, some do not survive the season. Double-coated dogs also struggle in the heat, and their shedding can drive their owners mad. These dogs are highly sensitive to temperature changes, and regular grooming is essential to improve air circulation through their coats.
Cold Weather
Similarly, cold weather can make dogs lazy, especially short-haired and leaner breeds. These dogs need extra rest during the winter because they lack the fur and fat necessary to keep warm.
On the other hand, long-haired and double-coated dogs thrive in cold weather—this is their time to shine.
Low Air Pressure
While humans rely on weather forecasts, dogs can sense changes in the weather, especially shifts in air pressure. Studies have found that dogs can detect storms or typhoons in advance.
Research from the American Veterinary Medical Association has shown that changes in air pressure can significantly impact a dog’s behavior. Some dogs may become restless or even aggressive in extreme cases, while others may become overly excited or curious—particularly before a storm or typhoon.
Rest assured, these behavioral changes are temporary. However, if your dog’s reactions are intense, it’s important to provide comfort and grooming to help them through the transition.
Seasonal Affective Disorder (SAD) in Dogs
Now, you might wonder, does this mean that dogs feel depressed throughout the year?
Let’s look at some data. According to a survey by the British Veterinary Charity Association, 40% of dogs in the UK show clear signs of emotional depression during winter.
While seasonal changes don’t always lead to depression, some dogs (about 40%) are suspected to suffer from a condition known as Seasonal Affective Disorder (SAD). In humans, SAD causes feelings of listlessness, depression, social withdrawal, and fatigue.
Dogs with SAD tend to sleep more and exercise less during winter. Researchers, using the same approach that helps humans with SAD, regularly exposed these dogs to sunlight. The British Veterinary Mercy Association discovered:
“The symptoms of SAD in both humans and dogs during winter are caused by increased melatonin, the sleep hormone. The pineal gland in both species secretes melatonin, and when outdoor light hits the retina, melatonin production stops, lifting the grogginess from the dog!”
