The Simple Way to Protect Your Dog From Dangerous Rock Salt

Winter can be a tough time for dogs. The cold weather usually means there are fewer opportunities for walks and more embarrassing accessories for them to wear. But the biggest threat to canines this time of year is one pet owners may not notice: the dangerous rock salt coating the streets and sidewalks. If you live someplace where this is a problem, here are the steps you need to take to keep your pooch safe until the weather warms up, according to Life Hacker.

Rock salt poses two major hazards to pets: damage to their feet and poisoning from ingestion. The first is the one most pet owners are aware of. Not only do large grains of salt hurt when they get stuck in a dog’s paws, but they can also lead to frostbite and chemical burns due to the de-icing process at work. The easiest way to prevent this is by covering your dog’s paws before taking them outside. Dog booties get the job done, as do protective balms and waxes that can be applied directly to their pads.

The second danger is a little harder to anticipate. The only way you can stop your dog from eating rock salt from the ground is to keep a close eye on them. Does your dog seem a little too interested in a puddle or a mound of snow? Encourage them to move on before they have a chance to take a lick.

If, for some reason, you forget to follow the steps above and your pet has a bad encounter with some winter salt, don’t panic. For salty feet, soak your dog's paws in warm water once you get inside to wash away any remaining grit. If your dog exhibits symptoms like vomiting, diarrhea, and disorientation and you suspect they’ve ingested rock salt, contact your vet right away.

Even with the proper protection, winter can still create an unsafe environment for dogs. Check out this handy chart to determine when it’s too cold to take them for a walk.

Why Do Dogs Sniff Each Other's Butts?

WHY? is our attempt to answer all the questions every little kid asks. Do you have a question? Send it to why@mentalfloss.com.

We might giggle when we see dogs sniffing each other’s rear ends, but there’s a good reason why dogs stick their noses in private places. It lets them find out all kinds of things about each other to help them get along and survive. A butt sniff for dogs is like a handshake for humans.

Dogs’ amazing sense of smell is 10,000 to 100,000 times better than humans. They also have a special part of their noses called the Jacobson's organ that lets them ignore the smell of poop when they sniff another dog’s rear. Instead, the organ detects something more important. On the sides of a dog’s anus (AY-nuss)—the place where poop comes out—are special glands that release chemicals telling the body how to grow and work properly. This is what interests dogs the most about each other’s butts. 

The chemicals tell dogs a lot about each other. They help a dog to know if another dog is male or female, how old it is, what it eats, how healthy it is, and even what kind of mood they’re in. The chemicals also help it to know if other dogs are strangers or if they’ve met before. All of this helps dogs decide how they should behave. It's how dogs first get to know each other!

Do Lobsters Really Mate for Life?

It's a pop culture trope that mated lobsters stay together until they die. But is it true?

Nope. While plenty of animals practice long-term monogamy, lobsters are not among them. Lobsters actually mate by a weird system of serial monogamy. It's not exactly a one-night stand, but it's not a lifelong commitment either. Instead, a bunch of females take turns having a fling with the local dominant male that lasts a week or two and, if they're not happy with the amount of genetic material he's provided, then seek a little extra action.

It works like this: A female lobster who's ready to mate (which they can only do right after they've molted) hangs out near the den of the local dominant male and fans her pheromone-laced urine into his home. This relaxes the male, making him less aggressive and more receptive to mating. Then there's a brief courtship, and the male allows the female into his den.

Anywhere from a few hours to a few days later, the female slips into something a little more comfortable by shedding her exoskeleton. (Shacking up with the neighborhood tough guy guarantees her protection during this vulnerable time.) The pair mates, and the male deposits his sperm in the female. Once her new shell has hardened a week or two later, she takes off, and another female can have her turn. Often, the females in an area will stagger the timing of their molts to make their reproductive conga line more efficient. As soon as one female is done with the stud, the next one is already waiting to pee on his doorstep.

Sometimes, the male doesn't provide enough sperm to fully fertilize all of a female's eggs. In these cases, she'll leave before her new shell finishes forming to find and mate with another male (or males) until she collects enough sperm. Usually this requires just an extra dalliance or two, but as many as 10 have been reported.
