10 Common Canine Care and Behaviour Myths Debunked

Old wives tales often circulate as dog care wisdom, but many are incorrect or even harmful. Understanding the truth behind common canine care and behaviour myths helps dog owners make informed, responsible decisions for their pets. This guide debunks 10 widespread myths with current veterinary advice.

1. Dogs Should Be Bathed Frequently

While washing a dirty or smelly dog is necessary, frequent bathing can strip natural oils from the skin, causing irritation and dandruff. Regular brushing maintains cleanliness and coat health by distributing oils evenly and stimulating circulation. Bath your dog only when truly needed, and use gentle dog shampoos.

2. Bad Breath Is Normal for Dogs

Bad breath is not a normal or healthy state for dogs and may signal dental disease. Establish a teeth cleaning routine early, use veterinary-recommended dental chews, and provide safe chew toys to reduce plaque. Persistent bad breath, inflamed gums, or trouble eating warrant a vet dental check and cleaning.

3. A Wagging Tail Always Means a Friendly Dog

Tail wagging does often indicate friendliness, but not always. It can also reflect excitement, submission, anxiety, or appeasement. Combine tail cues with other body language—such as ear position and facial expressions—to correctly interpret a dog's mood and avoid misjudging nervous or stressed dogs.

4. Garlic Gets Rid of Intestinal Worms

Despite old beliefs, garlic is ineffective against intestinal worms and can be toxic if overused. Use professional, vet-approved worming treatments on a recommended schedule to protect your dog. Garlic does have some benefits such as repelling biting insects when given in small safe amounts, but it’s not a worming solution.

5. Eating Grass Means My Dog Is Sick

Many dogs eat grass occasionally and may vomit afterward, but grass eating is a natural behaviour with unclear reasons. It might provide fibre or be a behavioural quirk. Watch for excessive grass eating or frequent vomiting, which can indicate health problems needing vet attention, but occasional grass consumption alone isn’t cause for concern.

6. Licking Helps Heal Wounds

Minor licking of small wounds can soothe and provide saliva enzymes aiding skin repair. However, excessive licking delays healing by causing irritation or infection. If your dog tends to lick wounds too much, your vet may recommend an Elizabethan collar (buster collar) to prevent further damage and allow proper healing.

7. A Dry Nose Indicates Ill Health

A wet, cool nose is often thought to signify a healthy dog, and dry noses indicate illness. In reality, nose moisture varies naturally with activity, environment, and sleep. Dry noses are common in restful periods and are not reliable signs of sickness. Always consider other symptoms like lethargy, appetite loss, or behavioural changes for health assessment.

8. Dogs Misbehave Out of Spite

Dogs lack the cognitive ability to act spitefully. Unwanted behaviours, such as barking or chewing, often stem from anxiety, boredom, or insufficient exercise. Addressing causes with enrichment, training, and routine reduces problems far better than punishment based on misconceptions.

9. Puppies Are Easier to Train Than Adult Dogs

While puppies may absorb new commands quickly, adult dogs often learn equally well or better, thanks to longer attention spans and prior socialisation. Training at any age requires patience, consistency, and positive reinforcement. Never assume an older dog is less trainable.

10. Tail Wagging Always Means a Happy Dog

Tail wagging can also signal alertness, uncertainty, or anxiety depending on how the tail moves and the dog's overall body language. Happy tail wags tend to be loose and fluid, whereas stiff or rapid wags might indicate nervousness or excitement. Look for the full body context before approaching.

Understanding and debunking these myths can improve dog welfare and strengthen the bond between you and your pet. Always consult your reputable breeders for healthy puppies, follow modern, science-based care, and seek veterinary advice when in doubt.
