There’s No Safe Amount of Time to Leave a Dog in a Hot Car

We often think of dogs as indomitable and durable animals who can fend off attackers, tirelessly chase Frisbees, and even eat poop without digestive consequences.

It’s true that dogs generally have a solid constitution, but that shouldn’t lead you to believe they can endure one of the biggest mistakes a pet owner can make: Leaving them in a hot car, even for a few minutes, puts a dog’s life at serious risk.

Even on relatively cool days with temperatures around 71.6°F, the inside of a vehicle can reach 116.6°F within an hour, as Quartz highlights.

If it’s a scorching summer heat wave, an 80-degree day will see temperatures get up to 99°F in just 10 minutes; a 90-degree day can turn the car into an oven at 119°F in the same amount of time.

Dogs can't tolerate this kind of heat. As their bodies struggle to cool down, the temperature is often more than they can expel through panting and opening capillaries in the skin. If their body reaches a temperature of 105.8°F, they're at risk of heatstroke, which only half of dogs survive. At 111.2°F, a lack of blood circulation can cause kidney failure and internal bleeding. Brain damage and death is very likely at this point. Depending on the outside temperature, it can happen in as little as six minutes. Cracking windows won't help.

Unless you plan on leaving your vehicle running with the air conditioning on (and we don't recommend that), there’s really no safe amount of time to leave a pet inside. If you do come back to find a listless dog who is unresponsive, it’s best to get to a veterinarian as soon as possible. And if you’re a bystander who sees a dog trapped inside a car, alert the nearest store to try and make an announcement to get the owner back to the vehicle. You can also phone local law enforcement or animal control. In some states, including California, you’re legally allowed to enter a vehicle to rescue a distressed animal.

It's difficult to think of a hobby or job that doesn’t involve some element of coding in its execution. Are you an Instagram enthusiast? Coding and algorithms are what bring your friends' posts to your feed. Can’t get enough Mental Floss? Coding brings the entire site to life on your desktop and mobile screens. Even sorting through playlists on Spotify uses coding. If you're tired of playing catch-up with all the latest coding techniques and principles, the 2020 Python Programming Certification Bundle is on sale for $49.99 to teach you to code, challenge your brain, and boost your resume to get your dream job.

Basically, coding is how people speak to computers (cue your sci-fi vision of a chat with a creepy, sentient computer), and while it does sound a bit futuristic, the truth is that people are talking to computers every day through a program called Python. The 2020 Python Programming Training Certification Bundle will teach you how to build web applications, database applications, and web visualizations in the world’s most popular programming language.

Python is also the language computers are using to communicate back to programmers. You’ll learn how Jupyter Notebook, NumPy, and pandas can enhance data analysis and data visualization techniques with Matplotlib.

Think back to your creepy, sci-fi visual from earlier; was it some form of artificial intelligence? Contrary to what you may have seen in the movies, artificial intelligence is something you can learn to create yourself. In the Keras Bootcamp, you’ll learn how to create artificial neural networks and deep-learning structures with Google’s powerful Deep Learning framework.

Coding is associated with endless text, numbers, and symbols, but the work code is performing is hardly limited to copy. Dig deep into image processing and computer vision tasks with sessions in OpenCV. You’ll give yourself an extra edge when you can use Python for sifting through information and implement machine learning algorithms on image classification.

Explore coding education with the bundle’s 12 courses, spanning from beginner to advanced levels, to elevate your skillset from home. The 2020 Python Programming Certification Bundle is on sale for $49.99.

Do Dogs Get Headaches?

Like babies, dogs can be hard to read in the medical ailment department. Are they listless because they’re tired, or because they’re sick? What’s behind their whining? And can they suffer that most human of debilitating conditions, the headache?

Gizmodo polled several veterinarians and animal behavior specialists to find out, and the answer seems to be a resounding yes.

Although a dog can’t express discomfort in a specific way, particularly if it doesn’t involve limping, animal experts know that canines that have diagnosed brain tumors or encephalitis can also be observed to have a high heart rate, a sign of physical pain. According to Tim Bentley, an associate professor of veterinary neurology and neurosurgery at Purdue Veterinary Medicine, administering painkillers will bring a dog’s heart rate down. If signs of physical distress also decrease, a headache was likely involved.

Unfortunately, not all dogs may offer overt signals they’re feeling some brain pain. According to Adam Boyko, an associate professor of biomedical sciences at the Cornell University College of Veterinary Medicine, dogs instinctively try to mask pain to avoid showing weakness.

Ultimately, dogs have many of the same central neural pathways as humans, which can likely go awry in some of the same ways. But the kind of persistent headaches owing to head colds or hangovers are probably rare in dogs. And while it goes without saying, they definitely don't need any of your Advil.
