If you have a dog, you know it's like having a child. They are messy, rambunctious, and have a hard time listening. Imagine being the parent to a child AND a dog! It's grounds for disaster. We've put together a list of reasons why you should never leave your child alone with your dog!

Leaving your baby alone with your dog might not be the best idea, especially if your cupboards are open. Even though you'll be spending quite a bit of time cleaning, and assuring they didn't eat anything poisonous, at least they got some valuable bonding time, right? Now they'll be the best of friends, and partners in crime, forever. We bet you've never seen a dog-riding Barbie!

It's apparent in this picture that this baby has a knack for film. Look at the way she has perfect control of her actors and the props. She's created the perfect scene and is sure to master the art of being a director. It probably also helps to have a dog that's as patient as this one. If you're a child of the 90s, you're sure to appreciate the next picture.

This child created her very own real-life Lisa Frank character and only needed a patient Dalmation and some magic markers. And since it looks like 90s trends are making a comeback, you just might be seeing more of this. This next picture is proof that growing up with cats can make you a bit crazy.

This child sure is learning a lot from her feline friends. For example, there's better uses for spilled milk than crying. Like, bending down and slurping it all up. It tastes just as good from the cup and there's no dirty dishes after. We all know dogs love playing catch, but this one wants to "catch 'em all."

We have to give credit to this kid for his creativity. After all, what better way to play Pokemon Go than to let your dog run around and do all of the work for you? There's no doubt in our minds that this kid will soon be on the top of all the leaderboards. If tech games aren't your thing, you might get along with this next cat, who has dived into the world of legos face first.

You can see by the look on this cat's face that he has no more of an idea of why he's in a sea of Legos, than we do. But it definitely looks like he does not approve. His poor little paws are certainly going to have a hard time trying to get out of that lego minefield. Giving a child some stickers is honestly just asking them to stick them in places that they shouldn't be.

It looks like this kid a future lover of body art, considering she had no problem turning her dog into a homage for Disney. But it doesn't look like this pup is going to appreciate her artwork when he's getting those stickers peeled out of his fur. If you've ever seen Toy Story, then you understand the importance of tea time. Looks like this dog knows the importance, too.

No one wants to have an afternoon tea engagement without any company, and this kid agrees. Since she can't call her friends, she used her closest buddy, her dog. She even knows that you can't exactly have a fancy tea party without wearing fancy tea party hats! It's just the way it goes. The next picture you can see a budding make-up artist.

We can't tell what's more impressive. The child's obvious make-up skills, or this cat's infinite amount of patience. Honestly, the cat looks kinda scary, but you have to give props where props are earned. What would you do if you got your kids a doll and they loved it more than you? What if they rubbed that love right in your face?

It's hard to picture a child being cruel, but here you go. This little boy is sitting at the window, feeding goldfish crackers to a stuffed dog, while his own dog is locked outside, staring in at him with envy. It looks like he might have a bit of sadism running through him. Do you enjoy dressing up your pet in ridiculous outfits? Well, this next one's for you.

Reddit/loflir10

It looks like this kid has taken some fashion advice from RuPaul's Drag Race. They did a fantastic job with the color-coordination, and that bright pink wig sure does bring out the dog's facial structure. But, she might want to try some different shoes. The dog might have a hard time walking the runway in those heels. Up next, the most patient cat in the world.

Reddit/teamcawkes

Not only is this cat been placed in a baby swing, he was also brought to the park on a leash. This kid might just be a cat whisperer. That, or this cat is keeping it cool and doesn't want to lead on that he's going to act out in revenge towards this child. This next picture is a reminder to make sure your under garments aren't left on the floor.

This kid is double trouble. Not only did he dress up his dog in inappropriate clothes, even though it's pretty funny, he also raided his mom's closet to do it. We hope the laughs were worth it because this just might get him grounded until his senior prom. Most cats don't like dressing up, but this one sure does...or maybe not.

That face is saying it all. He's sick of his little human's shenanigans and he's about to put a stop to it all. He looks as if he's thinking of a million different ways to kill her off in her sleep, or better yet, cover her in cat litter. Regardless, that little girl better tighten up soon, or that'll be the end of it all. Christmas is a time to be jolly. But, this next dog certainly doesn't agree.

Reddit/dobegood

This kid was getting in the spirit of Christmas, when he decided to take it a step further, and decorate his dog with yards of tinsel. According to this dog's face, he'll be hiding out next year when the Christmas decorations make their way out of the attic.

When we hear that someone has lived more than 100 years, it kind of blows our minds when we think about all of the things that they've lived through. But when we heard about a marine animal that may have been born before William Shakespeare, we were truly shocked. Could it even be true?

NOAA Okeanos Explorer Program

There is a mysterious creature living in the dark, frozen waters of the sub-Arctic ocean - a beast that goes by the name, Greenland Shark. This slow-moving animal is absolutely massive, and has managed to avoid humans at all costs, so there's not much that we know about it. But, recent studies have shown that the Greenland shark just might be the oldest living vertebrae on Earth!

The Inquisitr

A team of researchers from the University of Copenhagen published a paper last year with the results of a study they conducted in which they tried to determine the age of 28 different female Greenland sharks. Julius Nielsen, the lead author, determined that the oldest of the group could quite possibly be more than 500 years old! If this is true, the Greenland shark would take the title as oldest animal in the world.

Bangor University

Previously, the record holder for the oldest animal alive was the Icelandic clam, also referred to as an ocean quahog. The clam, which also goes by the name Ming, was an incredible 507 years old. Unfortunately, while they were still studying it, Ming died. But Ming wasn't the first species that was discovered to have lived more than a century.

Australia Zoo

The race for the longest-living animal seems to be led by the creatures living in the ocean. The Alaskan shortraker rockfish and the Namibian orange are both estimated to live up to roughly 200 years old, maybe even longer. Harriet, a Galapagos tortoise, lived to the incredibly old age of 170! They may be old, but the Greenland sharks definitely have them beat, but only if Nielsen was right about his estimations.

Verifying an animal's age isn't an easy task, especially one that has lived such a mysterious life. Researchers were alerted about their possible longevity by witnessing the Greenland shark's growth rate. They are suspected to grow approximately one centimeter a year! Despite their slow growth rate, they're one of the largest sharks on the planet, with lengths of up to 20 feet long! You may be surprised, but scientists think this is because of how cold their home is.

“In colder temperatures, growth slows and fish tend to get older,” reported Aaron Fisk, who has studied the Greenland sharks for 20 years. “It’s not hard to imagine that they could be 200 or 400 years old.” Nielsen and his team wanted to test this hypothesis, but they definitely had their work cut out for them.

Julius Nielsen

Some species of fish, like the salmon and cod, have otoliths -tiny bone structures, which have seasonal growth rings, kind of like the rings you can see in tree trunks. These rings allow researchers to figure out the fish's age. But, unlike the salmon, the Greenland sharks don't have otoliths, or hardly any calcified material, at all! So, there are no layers for scientists to count. The scientists then turned to a more complicated technique, found in an organ, to determine their age.

Gregory Skomal

All vertebrates have an eye lens that continues to grow throughout their entire life, but the core of the lens is formed before the animal is even born. The core contains a chemical signature from the environment the animal was in during its birth. Scientists use a technique called eye lens radiocarbon to help verify the age.

Instagram/juniel85

The first step they needed to take was trying to figure out if the animal was born prior to "the bomb pulse" - a series of thermonuclear weapons tests that occurred in the late 1950s that led to a huge spike in the amount of radiocarbon the atmosphere. Doing this showed the researchers that three of the sharks tested were born after 1960, but they never could've imagined how old the rest really were.

Nielsen's team then took the radiocarbon levels in the 25 sharks and compared them to a chronology of radiocarbon fluctuations that went back 50,000 years. They also assumed that the older the shark was, the longer it was, too. Using these calculations, they found the longest shark - a whopping 16 feet - was around 272 and 512 years old. Not all scientists agree with their conclusions.

Julius Nielsen

Other marine biologists don't believe that the size of the shark can determine how old it is. A specialist in verifying the age of marine animals, Allen Andrews, has said that previous studies have shown that the largest fish isn't necessarily the oldest. Nielsen understands the scientist's concern, but he still stands by the research his team has conducted.

Julius Nielsen

“At the end of the day, we completely agree it is possible that Greenland sharks of the same size can be different ages,” said Nielsen. Since the sharks that were without a doubt younger than 50 years old were also the smallest, he believes their method is working. Also, the information they provided was only an estimation, not a definite answer. Due to those facts, other researchers tend to agree with Nielsen.

“I wouldn’t want to put a date on it, but I think 400 or 500 years is in the realm of possibility,” said Fisk, the Greenland shark expert. “And that’s pretty extraordinary.” What's more important than their unbelievable longevity, is the findings that Nielsen's team found about how vulnerable the species truly is.

Julius Nielsen

Since Greenland sharks live for such an incredibly long time, that means they don't reproduce as often as species with shorter lifespans. So, if humans began exploiting them, their populations wouldn't bounce back as quickly as other species. And it would be naive to think that there isn't any commercial interest in the Greenland shark.

In the flesh of the Greenland shark is a high concentration of a chemical, that when eaten is metabolized to produce a similar effect that one feels when extremely drunk. Due to its effects, this shark meat is considered a delicacy in Iceland. Let's just hope that people don't start going crazy for their meat, and the Greenland sharks can continue to live their lives in peace, like they've done since the dinosaurs roamed the Earth.
