Dogs are fascinating creatures. They are loyal, adventurous, curious, able to work dozens of different jobs and be our most loving companion. But there are many things we don’t know and understand about our four legged friends, and as it often happens, misunderstanding breeds misinformation. The dog world is filled with misconceptions and myths about dogs, from behavior to getting rid of worms.
Here is a list of some common dog misconceptions, a little insight into what’s actually going on:
Myth #1: Dogs only see in Black and White:
Some Russian scientists took this popular myth and turned it on it’s head. Research has proven that dogs actually see in shades of blues and yellows, but can’t see shades of red. Who knew?! Check out this link to read more.

Myth #2: If you put garlic on your dog’s food, will it help get rid of his worms?
You’ve clearly never read my post about human foods dogs should avoid. Forget you ever heard this one. Garlic can actually be very harmful to a dog’s health, so just stick to putting garlic in your spaghetti sauces.
Myth #3: You can calculate a dog’s age by multiplying it’s human years by seven:
Research has actually shown this method to be outdated. By the time your dog reaches one year, they’ve already become a talking-back teenager, and the way they age varies from as they get older. Check this chart for exact conversions.
Myth #4: A cracked window is enough on a hot day:
Not even going there. Just read this
Myth #5: You can’t teach an old dog new tricks:
I can attest that this couldn’t be further from the truth. Sure, older dogs may suffer from hearing or vision loss, but that doesn’t mean they lose their ability to learn. This myth seems more like a human insult than a dog one.

One of the first lessons I teach parents about puppies is how to reduce biting. Simply give them a treat, and if their teeth touch your fingers too aggressively, pull the treat back and make a loud pitched noise. The dog will know to slow down in order to finally get the treat. I have used this trick on much older (8, 9, even 13 year old) dogs and it works great! They’ve learned a simple, new trick, and I get to keep all my fingers!
Still don’t believe me? Check out this video of MythBusters putting it to the test.
Myth #6: A dog’s mouth is cleaner than a human’s mouth:
Back story: Dog saliva was once believed to be antiseptic, and some people still believe it has healing properties. No one knows how that belief came to be, but it is still a common myth today. Trust me, a dog’s mouth is not “cleaner” than a person’s mouth. Dog saliva is capable of fighting off some bacteria, but carries it’s own army of bacteria and infectious organisms. The types of bacteria carried by humans and dogs is different, mostly because of the differences in diet. There is a reason for the term, “dog breath.”
Myth #7: Sex, litters and fixing your dog:
While compiling this post, I was surprised to see that lots of people wait before getting their dog neutered or spayed because they believe letting their dog have sex is a good thing, or that they need to have one litter of puppies “for the experience.”
But that’s simply not true. Sex results in puppies without homes or a good support system. Female dogs will not miss “the experience” of having a litter. There remains some controversy as to how early you should have a dog fixed, not fixing your dog leads to further animal population and control issues.
Myth #8: A fenced yard should be entertaining enough:
How would you liked being locked up in one space for long periods of time? The world is full of smells, sounds, animals to socialize with and trees to pee on. It’s important that a dog is exposed to all these things, not only for their socialization, but so they have the mental and physical stimulation to keep them from becoming destructive.

Myth #9: My dog should tolerate anything my children do:
This is a good way for your child to get a nasty bite wound. Children are terrible with boundaries, and they need to be taught to respect their doggie companions. Allowing a child to sit, tug on or tease a dog is disrespectful. Dogs are living animals that should be cared for, not tormented.
Myth #10: My dog understands me when I talk to him:
Even I fall into the trap of thinking I can “talk” to my dog. While dogs can understand about 500 words and a very talented Border Collie named Chaser can understand thousands, when we talk to our dogs they focus in on a few words, our tone of voice, facial expressions, and our body language.
Myth #11: Dogs wag their tail when they are happy:
A dog trainer I worked with actually debunked this for me. Dogs wag their tail for many reasons, but typically it’s because they are either happy or nervous. The important thing here is that you learn to read a dog’s body language. A stiff, rigid appearance is a good sign that your dog is nervous, even if their tail is wagging. Being able to read a dogs signals will go a long way to building strong relationships with them.
Who knew the dog world was filled with so many myths?
