Anything above 20C can cause your dog to become dehydrated and very hot very quickly. The hotter the temperature, the higher the risk to your dog. As the temperature increases, even by just 1C, the risk to your dog increases too. Any temperature over 25C is a definite NO when it comes to walking!
In cold temperatures 20 degrees and above: Large dogs (50-80 pounds) should be outside no more than one minute per degree. Medium dogs (25-50 pounds) can be outside for 30 seconds per degree.
It's generally safe in temperatures of up to 19°C (68°F) but be careful when the mercury rises above this. Even at temperatures as low as 20°C (70°F) dogs are at risk of heat stroke. Heat stroke in dogs is essentially a high temperature not caused by a fever.
While it depends on your specific animal and their breed, generally with lots of water, circulation of air, and shade, most pets will be fine in temperatures up to 90 degrees. But please remember there are no hard and fast rules here. Dogs don't sweat. They cool off by panting.
They say that between 16 and 19 degrees is generally safe for dogs, while between 20 and 23 degree is a six out of ten risk rating. When the temperature hits 24 and 27 degrees, this risk level goes up to nine out of ten, and then to ten out of ten when the weather reaches 32 degrees and above.
Generally speaking, dogs will be okay until the temperature drops to below 45°F. At that point, they may start to “feel” cold (and might seek out shelter or a way to stay warm). At 32°F, small dogs, elderly dogs, and dogs with preexisting health conditions should probably stay indoors.
What temperature is too hot for dogs? For any dog, 32° C / 89.6° F is considered too hot. At this temperature, your dog is prone to heat stroke, regardless of its breed or health. In a perfect world, the best temperature to walk your dog is between 12° C – 15° C / 53.6° F – 59° F.
An ideal temperature doesn't exist for all dogs, since their normal body temperature will vary according to size. Most dogs begin to show signs of overheating when the air temperature is between 81 and 85 degrees F.
The temperature range at which disease- causing bacteria grow best in time/temperature control for safety food (TCS) is called the temperature danger zone. Temperature danger zone is between 41°F and 135°F. TCS food must pass through the temperature danger zone as quickly as possible.
Avoid walking on hot days.
Temperatures below 25 degrees are optimum. Also, beware of the hot pavement so you don't burn their paws.
While small pups can spend a few hours outdoors in temperatures between 60ºF and 90ºF, keep outings in temperatures below 32ºF and above 90ºF to short spans of no more than 10 to 15 minutes, recommends Dr. Wooten.
Cold-Temperature Guidelines for Dogs
Once temperatures drop under 20 F, all pet parents need to be aware that their dogs could develop cold-associated health problems like hypothermia or frostbite when outside for extended periods of time.
Below 32°F – Owners of smaller breed dogs, dogs with short or thin coats, and/or very young, senior dogs, dogs with health conditions, or sick dogs should pay close attention to their pet's well-being. Below 20°F – All owners need to be aware that their dogs could potentially develop hypothermia and frostbite.
Anything under 45 degrees Fahrenheit can be unsafe for your furbaby and can cause hypothermia or frostbite. Since staying warm uses up extra energy, it's important that dogs have plenty of food while playing outside in chilly weather.
In Vets Now's assessment of temperatures for walking your dog, they state that between 20 and 23 degrees has a six out of 10 risk rating and that rigorous exercise in this heat could lead to heatstroke. An eight out of ten rating is given for 24-27 degrees celsius and they advise that extreme caution must be taken.
Keep temperatures closer to 78 or 80 degrees while you are away. Make sure to watch your dog for signs of being chilly when you're home and make any necessary adjustments.
Anytime your dog is in a car without AC, watch out for signs of heat stroke. They include excessive panting, weakness, muscle twitching and vomiting. If you think your dog has heat stroke, cool water or damp towels can help cool him down – and you need to get to a vet right away.
The optimum temperature for the well-being of pets is between 21 and 26 degrees Celsius, both in winter and summer.
Fans cool humans by evaporating the sweat on our skin. But because dogs don't sweat, the air flow from a fan isn't going to make much of a difference for them in the summer. So, leave the fan off to save money and energy.
Below freezing, 32°F, dogs in sensitive categories, such as older dogs and those with thin coats will need extra help, such as shelter (staying inside) or a jacket or sweater. Temperatures below 20°F are not safe for any dog to spend significant amounts of time outside, due to the risks of hypothermia and frostbite.
"Under 30 degrees, factoring in the wind chill, it's not going to be safe for any dog to be outside for an extended period of time," Smyth says." You can buy yourself a little bit of time with warm weather clothing," such as dog sweaters and booties to cover their paws.
As a general rule of thumb: at 45°F (7°C) and below, most dogs will dogs will start to become uncomfortable. at 32°F (0°C) and below, small, thin-coated, young, old and sick dogs should not be left outside for long. at 20°F (-7°C) and below, dogs become vulnerable to hypothermia and frostbite.
As a general rule, walking your dog at any temperature below 20C is ideal. Anything above 20C can cause your dog to become dehydrated and very hot very quickly. The hotter the temperature, the higher the risk to your dog. As the temperature increases, even by just 1C, the risk to your dog increases too.
Let's say it's 70 degrees Fahrenheit (around 21 degrees Celsius) — it's not risky for small-to-medium-sized dogs to play outside, but it is potentially unsafe for large dogs if they're not supervised.
