Why fall weather gives your dog more energy and zoomies

Fall is here, and more zoomies from your puppy companion may be, too.

If you’ve ever noticed your dog seems more energetic and playful when the seasons change to cooler months, you’re not imagining it.

Cooler weather, cooler dog

Dogs don’t sweat, so they cool themselves mainly by panting.

Summer forces them to burn energy just to stay cool, making them appear lazier since they have less leftover energy.

Now is the perfect time for more walks, since the weather is probably more palatable to you and your pet, who will appreciate the extra exercise.

As fall sets in, it'll get darker earlier, so don't forget to add safety lights or a reflective collar to make sure you're extra visible if you take any walks after the sun sets.

How temperature and seasons affect your dog varies somewhat by breed.

Northern breeds like American Eskimo dogs and Siberian huskies thrive in winter — the colder it is, the better they feel.

But other breeds, including hairless and toy breeds like chihuahuas, are more sensitive to the cold and may become less active, focusing on conserving their warmth over extra playtime.

You can bundle them up in a tiny jacket or boot to help them stay cozy and keep their paws warm, while still making time for exercise.

Senior dogs and those with health conditions are also more susceptible to being bothered by temperature extremes.

Tips for the seasonal energy shift

If the heat is lingering a little longer where you are, take advantage of the coolest parts of the day — mornings and evenings — rather than heading to the park during midday heat.

If you’re challenged by this sudden boost in energy, find new ways to stimulate your dog's mind and keep them distracted like puzzle toys.

Or if your dog has more energy than you’re able to keep up with, playing fetch is a good alternative when you’ve hit your limit on walks.
