Safe Temperature For Dogs Outside. The college of veterinary medicine at purdue university explains it this way: Dogs' temperatures should not reach over 104 degrees.
Can rise 20 to 30° above the outside air temperature due to the suns heating thus a 70° day can feel like 90 to 100° inside a locked car. Anything under 45 degrees fahrenheit can be unsafe for your furbaby and can cause hypothermia or frostbite. The normal range of temperatures at which dogs and other species can maintain their body temperatures without expending energy to increase heat production or heat loss is called the thermoneutral zone (tnz), and ranges from.68 degrees f to 86 degrees f for dogs.
