There is a lot of pervasive information available about dogs and their health. Unfortunately, a lot of it is simply untrue. Though sources may be well-intentioned, it is also possible for them to be misinformed. That is why it is so important to consult your dog’s vet when you need advice about pet health. Here are some dog health myths you’ve probably heard before that you should know the truth about.

1. Dogs Eat Grass to Make Themselves Vomit

There is a prevailing idea that dogs eat grass when they are nauseated to help themselves throw up something they shouldn’t have eaten. However, there is no evidence to suggest that this is true. In fact, most dogs don’t throw up every time they eat grass. Instead, there are many other theories that are much more likely.

Dogs may eat grass because they lack certain vitamins or minerals, such as iron. This is a condition known as pica, and it is generally not considered harmful — though you may want to supplement your dog’s diet with a multivitamin (with vet approval, of course). Dogs may also eat grass because it helps improve their digestion or because they have intestinal parasites. While you should certainly talk to your dog’s vet if your pet is eating grass regularly, it’s also possible that there is nothing wrong with your pet — some dogs just like to eat grass.

2. Your Dog’s Mouth Is Cleaner Than Your Mouth

No one is quite sure how this myth started. Dogs lick everything — their toys, their food and water bowls, your car windows, your face and everything in between. It is very likely that this myth began because it made pet owners feel better about their constant contact with dog saliva. Unfortunately, it simply isn’t true; your pet’s mouth is just as grimy as anyone else’s. After all, dogs lick everything, including some really disgusting stuff. Some dogs even eat feces! While your dog’s mouth may not naturally be full of bacteria, all the stuff they come in contact with on a daily basis certainly is, so you should stay far away from the licking or at least wash your face afterward if you can.

3. Dogs Are Healthier Than Humans

Dogs are naturally happy-go-lucky, resilient animals, so it naturally follows that they are rarely sick too. However, that isn’t always the case. While some dogs may never have a serious health condition, other dogs suffer from chronic ailments. They are really just like their owners in this way. Dogs can have any number of illnesses or diseases, including chronic ones such as autoimmune disorders and even cancer. Fortunately, you can prevent many common canine health conditions by scheduling regular vet visits and keeping your pet up to date on all his vaccines. If your dog is diagnosed with a serious illness, there are usually treatments available. For example, dogs with Cushing’s disease are often prescribed a daily medication such as Vetoryl 30mg to help control the symptoms.

Do Your Own Research

No matter what you hear, you should always do your own research when it comes your pet’s health. Only trust reliable sources (like your vet), and question any information that seems untrustworthy. If you have questions or concerns about your dog’s health, schedule an appointment with your veterinarian as soon as possible — it’s always better to be safe than sorry.
