There are plenty of myths and misconceptions about dogs. From tail wagging to the idea that you need to be the alpha, let’s separate fact from fiction by addressing 18 common dog myths.
1. When a Dog Wags Their Tail, It Means They Are Happy
One of the most common misinterpretations of dog behavior is the myth that a wagging tail always means a dog is happy. While dogs do wag their tails when they’re happy, they can also wag them out of fear, nervousness, or aggression. A slow, low wag may indicate insecurity, while a high, steady wag could signal aggression. The direction of the tail wag may even reveal a dog’s mood: wagging to the right could mean happiness or confidence, while to the left suggests unease.

2. One Year of a Dog’s Life Equals Seven Human Years
The idea that one dog year equals seven human years is an oversimplification. Dogs age differently depending on their breed, and this myth is based on outdated calculations. A 2019 study by researchers at the University of California, San Diego, showed that a 1-year-old dog is comparable to a 31-year-old human, while a 5-year-old dog is like a 57-year-old human.
3. You Need to Be the Pack Leader
The “alpha dog” myth has been widely circulated, but it’s based on faulty science. Originally, it was believed that wolves in the wild competed to be the dominant “alpha” wolf. However, modern science reveals that wolf packs function more like human families, with the “leader” being a caring parent, not a dictator. You don’t need to dominate your dog or enforce strict hierarchies. The focus should be on a balanced relationship and mutual respect.
4. Sleeping with Your Dog Is Not Good for You
Some people warn against letting dogs sleep in the bed due to potential health risks, but recent research from the Mayo Clinic suggests otherwise. As long as your dog is healthy and free of parasites, sharing your bed may actually improve your sleep. Just ensure your dog is up-to-date on vaccinations and has no health issues.
5. Once a Dog Bites, It’s Time to Put Them to Sleep
It’s a common misconception that a dog who bites cannot be trusted again and should be euthanized. While a bite can be alarming, aggression is treatable. The cause of the bite should be investigated, and with proper training and behavior consultation, many dogs can overcome aggressive tendencies.
6. A Tired Dog Is a Good Dog
While it’s often suggested that a tired dog is a well-behaved one, over-exercising your dog can lead to hyperactivity. Instead of simply tiring them out physically, focus on providing both physical and mental stimulation to ensure a balanced, well-behaved dog.
7. Dogs Should Eat Like Wolves
While dogs share a common ancestor with wolves, their dietary needs have evolved. Dogs are omnivores, not strict carnivores, and require a balanced diet that includes not just meat but also fat, vegetables, and fruits for proper nutrition.
8. Dogs Only See in Black and White
Dogs have a narrower color spectrum than humans, but they are not colorblind. They can see shades of gray, blue, and yellow. This helps them navigate the world, particularly in low-light conditions such as dawn and dusk.
9. What Is Safe for Humans Is Safe for Dogs
Not all human foods are safe for dogs. Common foods like chocolate, grapes, onions, avocados, and artificial sweeteners (like xylitol) are toxic to dogs. Always check food labels and avoid sharing potentially harmful treats.
10. Playing Tug Will Make Dogs Aggressive
The belief that tug-of-war games can make a dog aggressive is a myth. Tug games can be a great way to bond with your dog and provide them with physical and mental exercise. When done correctly, tug-of-war can be a healthy, fun activity for both you and your dog.
11. Dogs Express Guilt
While dogs can feel fear, sadness, and joy, they do not experience complex emotions like guilt. When a dog appears guilty, they are likely responding to your tone or body language, not recognizing that they’ve done something wrong. This behavior is known as appeasement, a way to diffuse tension when they feel threatened.
12. A Dog’s Mouth Is Cleaner Than a Human’s
Many people believe that a dog’s mouth is cleaner than a human’s, but that’s far from true. Dogs’ mouths are filled with bacteria, and their licking behavior can introduce germs, especially since dogs often eat things from the ground or garbage. So, kissing your dog may not be as safe as it seems.
13. Dogs Eat Grass When They Are Sick
While some believe that dogs eat grass to make themselves vomit, studies show that only a small percentage of dogs vomit after eating grass. Most dogs eat grass to increase their fiber intake and aid digestion.
14. Some Dog Breeds Are Hypoallergenic
No dog breed is truly hypoallergenic. While some dogs shed less, all dogs produce allergens. Dogs that shed less may reduce the amount of allergens in the environment, but they still can cause allergic reactions in sensitive individuals.
15. Old Dogs Can’t Learn New Tricks
It’s a common myth that older dogs can’t learn new things, but dogs of all ages are capable of learning new tricks with patience and training. Older dogs may even benefit from the mental stimulation that training provides.
16. Dog Saliva Can Heal Wounds
While some people believe dog saliva can help heal wounds, this is a dangerous myth. Dog saliva can introduce bacteria into wounds, leading to infections. It’s best to keep your dog’s mouth away from any cuts or injuries you might have.
17. When Dogs Lick You, It’s Their Way of Kissing You
While many people think that when a dog licks them, it’s a form of affection, it’s more likely that your dog is gathering information about you or enjoying the taste of your skin. This licking behavior may stem from an instinctual action where wolves lick their mother’s mouth to obtain regurgitated food. It’s part of a dog’s natural instincts, not necessarily a “kiss.”
18. Dogs Only Want to Please Their Owners
Although many dogs are eager to please, their behavior isn’t always driven by a desire to make their owners happy. Dogs may perform certain actions because they’ve learned that it results in rewards or attention. They are motivated by their needs, comfort, and desires as well.
Understanding these myths can help you better care for and understand your dog’s behavior and needs.
