So, is 21 degrees too hot? Only if you ignore common sense and your dog’s specific personality. For the average, healthy dog, it’s a fantastic temperature for a relaxed walk. For a fluffy, flat-faced, or senior pooch, it’s a “proceed with caution” situation, like eating spicy food before a date.
Ultimately, your dog will tell you more than the thermometer ever can. If your dog is prancing, sniffing, and wagging their tail like a metronome at a death metal concert, you’re golden. If they’re suddenly interested in every patch of shade, dragging their paws, or giving you the “human, what have you done to me” stare, it’s time to abort mission. Listen to your dog, bring water, and remember: it’s always better to cut a walk short than to spend the evening googling “cold towel on dog head.” Now go enjoy that 21-degree breeze—you’ve earned it.
