Is it true that a wagging tail always means a happy dog?

No, not always. While tail wagging can mean excitement or happiness, it can also signal anxiety, frustration, or even aggression. The direction, speed, and position of the tail all matter. It's important to observe your dog’s entire body language to truly understand their emotional state.

Why do people think dogs look guilty when they’ve done something wrong?

That so-called “guilty look” is actually your dog reacting to your tone and body language—not a sign of remorse. Dogs live in the moment and don’t feel guilt like humans. If they look ashamed, they’re probably just trying to avoid punishment. It’s a learned response, not a moral one.

Is it bad to let my dog sleep in bed with me?

Not at all, unless it’s causing behavioral or sleep issues for either of you. Sleeping together can strengthen your bond and offer comfort to both the dog and owner. It doesn’t “spoil” your pet—it actually reinforces trust. As long as you both sleep well, it’s a personal choice.

8 Common Dog Myths That Are Total BS (But Everyone Believes Them)

Think you know your dog? Think again. From wagging tails to guilty puppy eyes, there’s a lot of “common knowledge” about dogs that’s actually total BS. These 8 popular myths are fooling even the most devoted dog parents and some might even be hurting your pup without you knowing it. Whether it’s the lie about warm noses or the myth that mutts are “less healthy,” we’re busting it all wide open. This no-fluff guide will have you rethinking everything you thought you knew about your furry best friend. Warning: You might want to call out your vet (or your grandma) after reading this.

From wagging tails to eating grass, there's a TON of outdated, flat-out wrong “dog wisdom” floating around. Some of it’s harmless. Some of it might actually make life harder for you and your dog. But all of it? Busted.

Myth 1: A Wagging Tail Always Means a Happy Dog

Reality:
Wagging doesn't automatically mean “yay!” Dogs use their tails to communicate a wide range of emotions—fear, anxiety, frustration, alertness, even aggression. A slow, stiff wag can be a warning sign. A super-fast wiggle with a wiggly butt? That’s your happy pup.

Bottom line: Learn to read your dog’s body language, not just their tail.

Myth 2: Dogs Eat Grass Because They’re Sick

Reality:

Nope, your dog isn’t dying just because they munched your lawn. Many dogs eat grass out of boredom, curiosity, or simply because they like it. While some may vomit afterward, most don’t.

Bottom line: If it’s occasional and they seem fine otherwise, it’s totally normal. Don’t panic.

Myth 3: You Can’t Teach an Old Dog New Tricks

Reality:
This one’s just ageism in disguise. Older dogs can absolutely learn new tricks, behaviors, and routines. In fact, they often focus better than puppies because they’re calmer and more patient.

Bottom line: Got an older dog? Go ahead—teach them that cool new trick. They’re ready.

Myth 4: Letting Your Dog Sleep in Your Bed Will “Spoil” Them

Reality:
Sleeping in your bed won’t ruin your dog. In fact, it can strengthen the bond between you and your furry BFF. As long as both of you are sleeping well and there are no behavioral issues, there’s no reason not to.

Bottom line: If you love cuddles and your dog does too go for it.

Myth 5: If a Dog’s Nose is Warm, They’re Sick

Reality:
A warm or dry nose doesn’t necessarily mean your dog has a fever. Nose temperature fluctuates throughout the day due to weather, activity, and even sleep. Real signs of illness? Lethargy, loss of appetite, vomiting, and behavior changes.

Bottom line: Stop the nose obsession. It’s not the canine thermometer.

Myth 6: Purebred Dogs Are Healthier Than Mutts

Reality:
Actually, mutts often have fewer genetic health issues than purebreds. Inbreeding and closed gene pools in some purebred lines can increase the risk of inherited diseases.

Bottom line: Don’t judge a dog by its pedigree. Health depends on genes, not the price tag.

Myth 7: Dogs Feel Guilty When They Look “Ashamed”

Reality:
You know that guilty face? The sad eyes? The tucked tail? Hate to break it to you, but that’s not guilt—it’s just your dog reacting to your tone and body language. Dogs don’t feel guilt the same way humans do.

Bottom line: They’re not sorry they chewed your shoe. They’re sorry you’re mad.

Myth 8: My Dog Knows What They Did Wrong

Reality:
Dogs live in the moment. Unless you correct them immediately, they won’t associate your scolding with whatever they did—whether it was peeing on the rug or stealing food. Delayed punishment only confuses them and damages trust.

Bottom line: Training is about timing, not blame.

Stop Believing the BS

Dogs are smart, lovable, and endlessly fascinating but they’re also wildly misunderstood. The more we learn to unlearn the myths, the better we can care for them, train them, and enjoy their amazing company.

So next time someone says, “That dog has a warm nose must be sick!” or “Old dogs can’t learn,” hit ‘em with the truth. Because being a dog parent isn’t just about cuddles it’s about knowing better.
