With the bitter blast of arctic air hitting many parts of the country in 2018, horrifying stories are surfacing about dogs left out in the cold.

Watchdog Mary has been inundated with messages from concerned people asking for advice about dogs they've seen left outside, even chained to doghouses, in chilly, freezing temperatures.  

Some have called police and animal control, and ended up outraged when officers decided a dog's conditions aren't that bad, and the dog remains in a snow covered yard.   

So just how cold, is too cold, for a dog to be left outside? When is it cruel? When is it dangerous? 

There's basic common sense which prevails for many pet parents and officers: If it feels cold to you, unless you own a sled dog, it probably feels cold to your pooch, don't leave them outside. If you have to think, "Gee, is it too chilly for my dog to be out?" Bringing them inside certainly can't hurt. 

Cold weather evaluation chart

For those who need it spelled out in black and white, Tufts University, one of the top vet schools in the United States, created this Animal Condition and Care chart.  Veterinarians used scientific calculations to help evaluate when a dog may be in danger. (Click on the link above for the entire assessment document.)

But if reading numbers and graphs seems too confusing, and you're still puzzled figuring out "how cold, is too cold?" Watchdog Mary contacted the American Medical Veterinary Association, (AMVA), a respected authority on animal care. 

Lori Teller, DVM, who is on the AMVA Board of Directors, told Watchdog Mary, "Dogs can die because of the cold, people should take this seriously." 

Here is a simple way to figure this out: "If it’s uncomfortable for you to be outside, then your dog may not be that tolerant," Teller said. "If you have to bundle up, your dog may be cold too. If your dog looks miserable, or is shivering, it’s too cold." 

A dog's age, breed, and the climate they're used to also plays a role. "What a Chihuahua in Florida can tolerate is different than a Malamute in Minnesota," Teller said.

Tips on evaluating canines in cold weather

Teller says there's some key points to keep in mind evaluating dogs in the cold: 

  • Coat Type: If a dog has a thin coat, like a Chihuahua or a Bull Dog, they don't tolerate cold as well as some arctic breeds like a Malamute or Samoyed. 
  • Age: If a dog is older they may have a harder time compensating. 
  • Signs of distress: If a dog looks miserable, is shivering, becoming sluggish and not responsive, that is dangerous. Call police right away. 
  • Climate acclimation: Dogs who have always lived in Northern climates may be able to tolerate colder temps a bit more, but use common sense before leaving them outside. 

In fact, Teller warns, "Even if it’s a sled dog, they need to be kept warm at night. They can tolerate the cold for a longer period than other dogs, but they can’t tolerate it for any prolonged amount of time without having chance to warm up."

And if you think, "Oh, my dog has a dog house..." Keep this in mind, "Dog houses provide shelter from wind, not temperature," Teller said. "But if it’s really cold, or there's a prolonged freeze, a dog house won’t be of tremendous help. Ideally those animals would be brought inside."

Should dogs be "outside" dogs?

Speaking of dog houses, and dogs who are kept outdoors 24/7, many animal experts and rescue groups now say the same thing, "The 1950's called, they want their dog care advice back..." 

Besides being at risk of being too cold, exposed to the elements, thunder storms, or having a possible encounter with a wild animal, a snake, or an allergic reaction to a bee sting, dogs are social creatures, they like having a "family."  

"I think most dogs like being inside dogs. It’s not exciting to be a lonely dog in the yard by yourself," said Teller. "Dogs should be able to get out and get exercise, but should not be running loose of course. It’s not in the dog’s best interest to spend its life chained in a yard without social interaction, and it’s a risk to its physical health to be in temperature extremes." 

If you see a dog in questionable or dangerous conditions

  • Call your local police and the animal control officer.
  • Document days, times and the conditions you observe.
  • Take pictures and videos.

Tips for dog owners dealing with cold weather

If you weren't a believer in bringing your dog indoors in the cold, you must be by now. Here's some tips to help get you and your pooch through the winter:

  • Put a sweater or coat on your dog for walks and potty breaks.
  • Do shorter walks and indoor activities for exercise.
  • If your dog's activity level is decreased due to the cold, they may need a bit less food than normal. Make sure your pet doesn't put on winter weight. 
  • Be careful of liquids on the road, it could be antifreeze, which is very toxic. 
  • Wipe the road salt and anti-icing chemicals off your dog's paws.
