Who's a good boy?

Have you ever wondered why dogs wag their tails when they're happy? It's actually because tail wagging is one of their main ways of communicating emotion. Since they can't speak our language or communicate in that way, physical movements speak for them. When a dog is excited or pleased, their brain releases chemicals like dopamine and oxytocin, known as the "feel good" chemicals and neurotransmitters. These activate muscles throughout the body which start moving automatically, like the tail. It's not random either; the type of wag matters! A loose, wide wag often signals happiness and friendliness, while a stiff or slow wag can mean something very different.

Dogs wag their tails directionally, as well. Studies have found that when dogs feel positive emotions, their tails tend to wag more to the right side of their body. This is linked to activity in the left hemisphere of the brain, which processes positive feelings and social behaviors. Other dogs can even pick up on these subtle cues, reading emotional information from another dog's tail movement.

When it's the weekend, it can be so tempting to just stay indoors, especially if you have a pet. Having a pet like a dog may motivate people to take the dog outside for playtime, dog parks, hiking, or running around a grassy area. But when the weather's cold, it's so much more enticing to simply stay inside, snuggle with your dog, and scroll wholesome and hilarious dog memes together in the comfort and warmth of your home.

A random but fascinating scientific fact about dogs: their sense of smell is so powerful that it's closely tied to their emotional memory (similar to humans with smell and memory). Don't smell what something is, and simultaneously they remember how it makes them feel, which is why they can easily get so excited seeing their owners. It's because the owner's smell is triggering their emotional happiness. Scent information goes straight to parts of the brain connected to emotion and memory, like the amygdala. That's why a dog can become instantly calm, excited, or anxious when they smell a familiar person or place.
