10 common pet myths veterinarians want you to stop believing for your pet’s well-being

What if some of the most “helpful” guidance you’ve ever received about caring for pets isn’t just slightly outdated—but quietly inaccurate in ways that actually matter? Advice that sounds comforting, gets repeated across generations, and feels too familiar to challenge can sometimes drift far from what modern veterinary science supports. From everyday habits to deeply rooted assumptions about animal health and behavior, many pet owners may unknowingly rely on ideas shaped more by tradition, anecdotes, or social media than by evidence. The unsettling part is that these misconceptions rarely appear questionable at first glance—they often come wrapped in confidence and familiarity, reinforced by the belief that “this is just how pet care works.”
We share our homes, routines, and emotional lives with our pets, yet much of what we believe about their care doesn’t always come from scientific understanding. Instead, it is often passed along through word of mouth, internet posts, or long-standing beliefs that continue to circulate despite being debunked. While these ideas usually stem from genuine concern for animals, they can still lead to misunderstanding and, in some cases, prevent proper care. That’s why separating fact from fiction is so important when it comes to the well-being of our companions.
Building a clearer understanding of a pet’s health, instincts, and needs is a key part of responsible ownership. Misconceptions such as “dogs have cleaner mouths than humans” or “cats always land safely after a fall” remain widespread, even though veterinary experts consistently clarify otherwise. Replacing these long-held beliefs with accurate, science-based information helps ensure pets receive safer, more effective care throughout their lives.
To explore these myths in greater detail, we spoke with Dr. Rory Lubold, DVM, MBA, CCRT, Head of Veterinary Services at Yourgi, a pet care platform that connects owners with trusted professionals. He outlined several of the most common misconceptions veterinarians wish people would stop believing. Cats always land on their feet

This widely repeated idea is not entirely true. Although cats have a remarkable ability to reorient themselves mid-air using their righting reflex, Dr. Lubold notes that this does not make them invincible. Falls—especially from significant heights or awkward surfaces—can still result in serious injuries despite their agility.
A dog’s mouth is cleaner than a human’s
A common misconception suggests that dogs have “cleaner” mouths than humans, but this is
not supported by veterinary science. A dog’s mouth contains a complex mix of bacteria, and exposure through bites or licking open wounds can easily lead to infection. While normal affectionate contact is generally safe for healthy individuals, extra care should be taken around broken skin or vulnerable immune systems.

Table scraps are always unsafe for dogs
Many owners believe dogs should never eat human food, but the reality is more balanced. Certain fresh, minimally processed foods can be safely included in a dog’s diet when offered appropriately. However, ingredients such as grapes, onions, and garlic are toxic even in small quantities. When given consistently and in moderation, some table foods can be incorporated without harm, depending on the dog’s overall diet.
Senior pets are too old for dental care
Age alone should not prevent dental treatment. In fact, dental disease tends to worsen over time and can contribute to broader health complications affecting organs such as the heart, kidneys, and liver. With proper veterinary evaluation and adjusted anesthesia protocols, dental cleanings can still be performed safely in older pets, often greatly improving comfort and quality of life.

Indoor pets don’t require parasite prevention
Even pets that remain indoors are still at risk of parasite exposure. Fleas, ticks, and mosquitoes can enter homes and act as disease carriers. While staying indoors lowers exposure, it does not eliminate it entirely. Preventive care remains important regardless of a pet’s environment or lifestyle.
Cats don’t need veterinary checkups if they appear healthy
Cats are known for hiding signs of illness, which means health issues can progress unnoticed for long periods. Routine veterinary exams and diagnostic testing play an important role in detecting early changes that are not visible at home. Relying solely on outward behavior can delay diagnosis and treatment.
Occasional vomiting in cats is always normal

While occasional vomiting—such as hairballs—can occur, frequent or repeated episodes should not be dismissed. Ongoing vomiting may signal underlying conditions such as digestive disorders, food intolerance, or other medical concerns that require attention.
Mixed-breed dogs cannot inherit genetic conditions
Although mixed-breed dogs may benefit from greater genetic diversity, they are not immune to hereditary diseases. They can still develop conditions linked to their genetic background, as well as other inherited disorders. Regular veterinary screenings remain important regardless of breed type.
Dogs do not need sun protection

Dogs can experience sunburn, particularly on areas with thinner fur such as the nose, ears, and belly. Short-coated breeds are especially vulnerable. Using pet-safe sunscreen and limiting exposure during peak sunlight hours can help protect their skin from damage.
Bad breath in older dogs is just normal aging
While bad breath is common in senior dogs, it should not be accepted as normal. It often indicates dental disease or other underlying health issues. Identifying the root cause early can prevent discomfort and help avoid more serious complications. By distinguishing fact from fiction, pet owners can make better-informed decisions and provide more effective care for their animals. Veterinary professionals consistently emphasize that staying informed—and being willing to question long-held assumptions—is one of the most important steps toward ensuring pets live healthier, safer, and happier lives.
