The Surprising Reasons Your Dog Curls Up in a Ball Before Going to Sleep

Besides being great companions and painfully cute, dogs can be a little quirky. Between their funny expressions and odd behaviors, each of our furry friends has eccentricities that make us love them even more. But some of the adorably weird things they do are actually an innate part of being a canine, which might come as a surprise to some pet parents.

Take, for example, when dogs curl up in a ball before falling asleep. To the average pet owner, this probably just seems like a way to get comfortable before dozing off. And while that could be part of it, Dr. Margaret Gruen—an assistant professor of Behavioral Medicine at NC State University's College of Veterinary Medicine—said that the behavior is also firmly rooted in evolution.

"When dogs sleep in the wild, especially where it’s cold, they’ll dig a nest and curl up into it," Gruen told Vetstreet. This gives them warmth—tucking into a ball conserves body heat. It also protects their most vulnerable organs in the abdomen from would-be predators."

Yes, she's saying your dog gets into this position so no one comes for their organs. It sounds silly for your beloved pooch, but it's a reasonable tactic for their wild ancestors.

The next reason makes more sense, and it's that your dog is making his or her own nest when they curl up in an attempt to stay safe in a possibly foreign area. Even if your dog is at home, they still often revert back to basic instincts when getting ready for sleep, as it's a vulnerable state. Which makes sense. And it turns out that there's a whole host of reasonable explanations for your dog's other odd behaviors; here are just a few of them.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

The 10 Best Shark Movies of All Time, According to Rotten Tomatoes

If the ongoing popularity of shark films has taught us anything, it’s that we simply can’t spend enough screen time with these predators, who can famously ruin a beach day with one swift gnash of their teeth. And even if shark attacks are far less common than Hollywood would have us believe, it’s still entertaining to watch a great white stalk an unsuspecting fictional swimmer—or, in the case of 2013’s Sharknado, whirl through the air in a terrifying cyclone.

To celebrate Shark Week this week, Rotten Tomatoes has compiled a list of the best shark movies of all time, ranked by aggregated critics' score. Unsurprisingly topping the list is Steven Spielberg’s 1975 classic Jaws, which quite possibly ignited our societal fixation on great white sharks. The second-place finisher was 2012’s Kon-Tiki, based on the true story of Norwegian explorer Thor Heyerdahl’s harrowing voyage across the Pacific Ocean on a wooden raft in 1947.

If you did happen to write off Sharknado as too kitschy to be worth the watch, you might want to reconsider—it ranks sixth on the list, with a score of 78 percent, and its 2014 sequel sits in ninth place, with 61 percent. The list doesn’t only comprise dramatized shark attacks. In seventh place is Jean-Michel Cousteau’s 2005 documentary Sharks 3D, a fascinating foray into the real world of great whites, hammerheads, and more.

But for every critically acclaimed shark flick, there’s another that flopped spectacularly. After you’ve perused the highest-rated shark films below, check out the worst ones on Rotten Tomatoes’ full list here.

  1. Jaws (1975) // 98 percent
  1. Kon-Tiki (2012) // 81 percent
  1. The Reef (2010) // 80 percent
  1. Sharkwater (2007) // 79 percent
  1. The Shallows (2016) // 78 percent
  1. Sharknado (2013) // 78 percent
  1. Sharks 3D (2004) // 75 percent
  1. Open Water (2004) // 71 percent
  1. Sharknado 2: The Second One (2014) // 61 percent
  1. Jaws 2 (1978) // 60 percent
