Dogs do weird stuff, that's true. That's also one of the reasons we love them. Interestingly, many of these odd behaviors are fairly logical and explainable. Ever wondered why your dog likes to eat grass so much? Why is the bathroom garbage so appealing to your pooch? 

Read on and find out what's the reason behind these and other strange behaviors our dogs exhibit. Below you'll find some things dogs do that we, owners, find peculiar, but that have very reasonable explanations behind them.

Let's start with the intense eye contact. There are three instances when your dog might look at you in an unusual way. When they get scolded, when they're pooping or they're just watching you getting ready.

The guilty look in a dog's eyes is a response from an immediate or past negative reaction from the owner. They give those guilty eyes as they await a response. If your pooch is looking at you while they're pooping – they're looking for signs of danger. 

At that moment, they trust you to defend them. And the constant looking at you at home is just always being ready for affection, treats or food. A dog behavior expert Madeline Friedman told The Dodo that some dogs also might expect a reward for doing their business outside.

What about the crazy running around, back and forth either inside or outside? The "zoomies," as professionals call them, are random bursts of hyperactivity. "They are bursts of energy like a volcano. Energy builds up then there is the expression and release of that energy," Certified Applied Animal Behaviorist Jill Goldman, Ph.D., told the American Kennel Club.

This next one is why most cats in cartoons look down on dogs as dumb – chasing their tail. There are two completely benign reasons for it: either they're looking to expend some energy or want the owner's attention.

But it also can become something worth serious concern. Veterinarians say some dogs might do it because they have OCD. If a dog does it excessively or injures himself, go see a vet.

Our next category is the munchies. The first one on the menu – grass. Many owners might become concerned when their pet starts crunching the green stuff, but it's not always a red flag. Dr. Leanne Jakubowsky, DVM told Business Insider that dogs use grass as a purgative.

Apparently, it helps them "clear out foreign bodies and parasites due to the high fiber content of grasses." Some might also start eating it due to nutritional deficiencies, yet it's less likely since dog food nowadays is well-balanced.

Some dogs like to munch on non-food items. Toilet paper, stuffed animals, homework – hardly anything is off limits. The behavior when dogs eat things that are not foods is called pica.

PetMD writes that the most common reasons behind it are mental: boredom, depression, anxiety or extreme hunger. It mostly occurs in high-energy breeds (like Labradors) who don't get enough attention and exercise, and lack socialization with other dogs or humans.

The most extreme (and gross) case of pica is when a dog eats its own poop. Coprophagia is the medical term for it and is common with young puppies and nursing females. In fact, it's pretty normal for dog moms – they ingest the stuff while cleaning their pup or stimulating their bowel movement.

Let's move on to some weird behaviors that aren't so stomach-turning. My puppy stashes food and toys in his secret hideout. What's up with that? With all types of hoarding, it comes down to instinct.

Animal Behavior College Dog Trainer Deborah Fenton told the AKC that "most of the time when dogs hide things, they do so because they have an instinct to hoard or guard their food and possessions."

If there's one thing dogs love, it's marking their territory. That's the reason why they start kicking right after doing their business. Preventative Vet writes that it's how they send a message to other dogs.

"There are scent glands on and in between your dog's paw pads. Scratching the grass after urinating or defecating helps spread the pheromones secreted by these glands around the area."

The last one: splooting. It's a funny resting position where a dog stretches their hind legs while lying down, resulting in a pretty comfortable position.

Experts say that it's a way for doggos to stretch their hip muscles and relieve pressure on their lower and back hips. That's especially true with older dogs.

Another reason can be to cool off – the position exposes more of their skin. My beagle, for example, used to sploot on the cold tiled kitchen floor after coming back from long walks in the hot summer. So that one’s definitely true!
