Wolf Puppies Play Fetch, Too, Study Finds

It took thousands of years of selective breeding for wolves to become the Golden Retrievers you see at dog parks today. Domesticated dogs are very different from their wild counterparts, but according to a new study, they may have a surprising trait in common. Researchers found that some wolf puppies are willing to play fetch with total strangers, suggesting that following human commands is intrinsic to canines.

For their study in the journal iScience, researchers from Stockholm University in Sweden set out to find how domestication affects behaviors in young wolves. They raised litters of wolf and dog pups separately from 10 days old and placed them in various scenarios.

When the scientists tested how the wolf puppies would respond to a game of fetch, they expected to be ignored. Chasing a ball and bringing it back requires understanding human commands and obeying them—abilities that were thought to only have emerged in dogs post-domestication.

The first two wolf groups met expectations by showing little interest in the toy, but something different happened with the third set. Three eight-week old pups went after the ball and brought it back when they were encouraged to do so. This was the case even when the person giving the commands was someone they had never met before.

Even though most of the puppies didn't play fetch, the fact that those who did belonged to the same litter indicates a "standing variation" for a retrieving trait in wolves. "When you talk about a specific trait in the context of standing variation, it means that there is variation for the expression of this trait within a given population," co-author Christina Hansen Wheat tells Mental Floss. "For our study it suggests that, while probably rare, standing variation in the expression of human-directed behavior in ancestral populations could have been an important target for early selective pressures exerted during dog domestication." In other words, ancient people seeking to domesticate wolves might have focused on some wolves' innate ability to follow human commands.

The first dogs were domesticated as far back as 33,000 years ago. Over millennia, humans have selected for traits like loyalty, friendliness, and playfulness to create the modern dog, but these new findings could mean that the dog's earliest canine ancestors were genetically predisposed toward some of these behaviors.

"All three litters were brought up under identical and standardized conditions across years," Hansen says of the pups in the study. "With this significant effort to control the environmental conditions, it is likely that the differences in behavior across litters to some extent have a genetic basis."

After raising the dog and wolf litters for three years and completing that part of their study, the researchers will continue to analyze their data to see if there are any other adorable (or weird) traits the two groups share.

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.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

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.

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 Reason Your Dog Stares at You

Sooner or later, every dog owner will find their pet expressing an innate curiosity over even the most mundane of actions. Watching television? The dog will observe you closely. Folding laundry? The dog will stare at you like you’re a Magic Eye poster.

You can tell the dog it’s rude, but they’ll continue doing it. So why do dogs stare at us?

It often has little to do with what we’re doing and is more about what we might do. Dogs are big on visual cues. They know a walk is preceded by you picking up their leash; dinnertime might involve going to the pantry; a car ride means grabbing the keys. If they get a treat by obeying a command, then they know you’re probably going to start pointing at them and want to make sure they don’t miss it. In keeping an eye on you, a dog is looking for hints that you’re going to do something they want.

Dogs may also use staring as a method to train their owner. Most people are more likely to slip a dog something off their dinner plate if the dog is looking up at them wistfully. If that behavior is rewarded, then the dog knows giving you a pleading look may result in some pork chops landing at their feet.

But not all dogs stare out of greed. For dogs, just like humans, making eye contact releases oxytocin, otherwise known as the “love hormone.” It’s a bonding experience for humans and their animal companions.

Of course, staring can have other connotations, particularly if it’s not a dog you know very well. An unblinking, focused stare with a rigid body posture can mean the dog is feeling territorial or might be considering taking a bite out of you. It’s best to back away. It’s also not advisable to hold a dog still and stare at them, as this might be considered an act of aggression.

The next time you catch your dog eyeing you, it’s likely they’re hoping for a walk, a treat, or just want to bond. Absent other methods of communication, staring is an effective way for getting their humans to behave.
