They say that dogs are man’s best friend, but some people don’t know a lot of facts about their closest companion.  There are tons of widely believed myths about animals, but dogs may have some of the most. People want to keep their dogs healthy with plenty of good food, exercise, and medications and with supplements likeheartgard for dogs.   If you want to give your dog the best life possible you should try to learn facts about them.  You may be surprised to learn which public accepted “facts” about dogs are nothing more than myths.
If your dog has a dry nose that means that they’re sick
Nobody knows how the wet nose myth got started, but now a lot of pet owners panic when they notice that their pooch’s nose is a little dry.  If you notice changes in texture on your dog’s nose, changes of color, or a prolonged period of nose dryness with cracked skin, it could be a sign of sickness. If your dog’s nose was wet an hour ago, but feels dry now, you most likely don’t have anything to worry about.  It’s perfectly normal for your dog’s nose to switch from being wet to being dry throughout the day.  As long as you don’t notice other symptoms (lethargy, open sores, loss of appetite) accompanying your dog’s dryness, their dry nose is nothing to worry about.
Dogs eat grass to make themselves vomit
It’s true that many dogs vomit after eating grass, but the widely believed reason behind their grass eating urges is wrong. Dogs eat grass simply because they like to eat grass. Some experts think that their grass eating behavior goes back to the days when wild dogs would eat the stomach contents of its prey.  Dogs end up vomiting after they eat grass because the grass can irritate their stomachs.  If you notice that your dog is an avid grass eater that throws up frequently, you should take them to the vet to get it checked out.  If it’s an occasional occurrence, don’t stress too much about it.
Dog mouths are cleaner than human mouths
This myth was probably spawned by someone who noticed that their dogs lick their wounds and see no signs of infection afterwards.  If a wound on your dog heals faster after licking, it doesn’t have anything to do with the cleanliness of their mouth. Their tongue managed to remove dead tissue and stimulated circulation, an effect that’s very similar to a surgeon debriding a wound.  Dog mouths contain plenty of germs, and since many dogs don’t get their teeth brushed as regularly as humans do, many dogs have a significant amount of plaque buildup. 
Spaying/Neutering your dog will make them act more masculine/feminine
This is a perfect example of humans anthropomorphizing their pets.  Dog don’t have a concept of gender or sexual identity, but their human owners do.  Maybe this myth got started because a dog owner noticed their pooch acting a little differently after getting them fixed, or maybe it’s because their owners are projecting their own feelings on to their dog.  Either way, the benefits of having your dog fixed outweighs any supposed myth about their behavior.
