Why Is My Dog Licking the Air with Head Up? Causes and What to Do

If you’ve ever caught your dog licking the air with their head tilted up, it might seem odd or even amusing at first. But while it can occasionally be a harmless quirk, persistent air licking can signal an underlying health or behavioral issue. Understanding the reasons behind this behavior can help you determine when to seek veterinary attention.

Common Reasons for a Dog Licking the Air

1. Something Tastes or Smells Interesting

Dogs experience the world through scent. If your dog licks the air with their head up, they might be picking up on a scent or taste that's lingering in the air. This can happen after eating, during a walk, or when encountering new environments. The Jacobsen’s organ in their mouth allows them to “taste” smells, and air licking helps draw scent particles in.

2. Dental or Oral Pain

Dental issues like gum disease, broken teeth, or something stuck in the mouth can lead to unusual licking behavior. Dogs may tilt their head up and lick repeatedly to relieve discomfort or attempt to dislodge debris. Check their mouth for redness, swelling, or signs of pain.

3. Nausea or Gastrointestinal Distress

When a dog feels nauseous, they may lick the air in an attempt to manage the sensation. Acid reflux (sometimes called canine GERD) or other GI issues like gastritis can cause your dog to act this way. Some owners report dogs licking the air just before vomiting or regurgitating.

4. Seizures or Focal Seizure Activity

Air licking with head movement can sometimes be a subtle sign of a partial or focal seizure, especially if the behavior is repetitive and appears “out of context.” Dogs may also seem disoriented, unresponsive, or have other brief neurological symptoms. If this behavior happens frequently or in episodes, consult your vet as soon as possible.

5. Obsessive-Compulsive Behavior

Air licking can become compulsive, especially in dogs experiencing chronic stress or anxiety. Dogs that are left alone for long periods or have a history of trauma may develop repetitive behaviors as a coping mechanism. These can include licking walls, air, or even themselves excessively.

6. Allergies or Skin Irritations

Dogs with environmental allergies, food sensitivities, or skin conditions may lick excessively due to irritation. Sometimes, the sensation might be internal (like an itch in the mouth or throat), causing them to lift their head and lick the air.

When to Be Concerned

If your dog occasionally licks the air and shows no other symptoms, it’s likely nothing serious. However, persistent, frequent, or sudden-onset air licking—especially when paired with symptoms like drooling, vomiting, head shaking, or lethargy—should prompt a veterinary evaluation.

Signs that warrant a vet visit include:

• Repeated episodes of air licking
• Changes in appetite or weight
• Vomiting, diarrhea, or excessive drooling
• Behavioral changes (withdrawn, anxious, agitated)
• Signs of pain when eating or chewing

How Vets Diagnose the Issue

Your veterinarian may perform:

• A dental exam and oral inspection
• Blood tests to check for GI or metabolic conditions
• Imaging (like X-rays or ultrasound) if seizures or internal issues are suspected
• Neurological evaluation, especially if seizure activity is suspected
• Review of behavioral patterns and history for OCD or anxiety

What You Can Do at Home

• Keep a behavior log: Note when and how often the behavior occurs.
• Record a video: This can help your vet better understand the pattern.
• Provide enrichment: Boredom and stress can worsen compulsive licking.
• Check for allergens: Food trials or allergy testing may be needed.
• Avoid punishment: This may increase stress and worsen the behavior.

Don’t Panic

A dog licking the air with their head up may look strange, but it’s not always a cause for alarm. Still, because it can point to issues ranging from nausea and dental pain to seizures or anxiety, it’s best to observe closely and consult your vet if the behavior is frequent or changes suddenly. Early diagnosis can help resolve the underlying problem and improve your dog’s well-being.
