Common Myths About Pet Health That New Owners Often Believe

This myth likely persists because dogs lick their wounds and people assume that means saliva is antiseptic. In reality, a dog's mouth hosts a complex bacterial environment suited to its own biology. Some of those bacteria can cause infections in humans, particularly in people with weakened immune systems, young children, or open wounds. Letting a dog lick a wound is not a safe home remedy. Keep wounds covered and wash any licked skin with soap and water.

A dog or cat's nose can be warm and dry after sleeping, during hot weather, or after exercise — all of these are entirely normal. Conversely, a wet nose doesn't rule out illness. What actually matters are behavioral changes: loss of appetite, lethargy, changes in bathroom habits, or discharge from the nose or eyes. If your pet seems unwell, trust those signs over nose texture, and call your vet.

The righting reflex allows cats to rotate their body during a fall, but it requires enough distance to activate — and it doesn't cushion impact. Falls from balconies, windows, or rooftops cause what veterinarians call high-rise syndrome, which can include fractured legs, chest trauma, and ruptured palates. Even falls from lower heights can injure small cats. Secure windows and balconies, especially in urban homes, and treat any fall from significant height as a veterinary emergency.

Pets instinctively mask discomfort, an evolutionary trait that helped wild ancestors avoid appearing vulnerable. This means your dog or cat can be experiencing real health problems while appearing outwardly normal. Annual wellness exams allow vets to catch issues early through physical examination and routine bloodwork. Preventive care is almost always less costly — financially and physically — than treating a condition that has gone undetected. The Pet Health & Vet hub is a good starting point for understanding what routine care involves.

Research suggests that most dogs who eat grass do not appear ill beforehand and do not vomit afterward. Current thinking among veterinary behaviorists is that grass-eating may be instinctive, related to fiber intake, or simply a learned habit. Occasional grass-eating in an otherwise healthy, active pet is generally not a cause for alarm. However, if your pet is eating grass obsessively, vomiting repeatedly, or showing other symptoms, that combination does warrant a vet call. Also ensure any grass or plants your pet accesses are free of pesticides and herbicides.

Waiting for bad breath to prompt dental care means the problem has already progressed. Plaque hardens into tartar within days, and tartar below the gumline can lead to infection, tooth loss, and — in severe cases — bacteria entering the bloodstream. Veterinary dental guidelines generally recommend annual professional cleanings for most dogs and cats, as well as home brushing with pet-safe toothpaste. Human toothpaste contains ingredients that are toxic to pets — never use it. See our detailed guide on pet dental health for practical steps.
