When an older dog begins licking excessively, it can be concerning and puzzling for pet owners.
While some licking is a normal behavior in dogs, constant or obsessive licking in a senior dog can signal an underlying health issue that needs attention.
We outline the common reasons why an old dog may excessively lick, what you can do at home, and when to seek veterinary help.

Old Dog Licking Excessively — Why It Happens
Excessive licking in older dogs is often linked to medical, behavioral, or emotional changes that come with age. Dental disease, gastrointestinal upset, joint pain, anxiety, and even neurological issues can all trigger persistent licking.
Sometimes, a dog may lick themselves, objects, or even their owners as a way of self-soothing. In senior dogs, these behaviors may be more pronounced due to age-related discomfort or stress.
Old Dog Licking Excessively: Common Causes
Dental Disease
Dental disease is one of the most common issues in older dogs. Gum infections, broken teeth, or painful abscesses can cause a dog to lick excessively in an attempt to ease oral discomfort.
You may also notice bad breath, drooling, or difficulty eating. Left untreated, dental disease can worsen quickly and impact a dog’s overall health.

Gastrointestinal Upset
Stomach discomfort or nausea often leads dogs to lick excessively. Older dogs may develop sensitive stomachs, acid reflux, or chronic conditions like inflammatory bowel disease.
If your dog is licking floors, carpets, or their lips frequently, it may be a sign of nausea or gastrointestinal pain.
Arthritis and Joint Pain
As dogs age, arthritis and joint pain become more common. Dogs sometimes lick or chew at the painful area as a way to cope with discomfort.
For example, a dog with hip arthritis may constantly lick their flank or paw. Over time, this can cause irritation, hair loss, or skin infections.
Anxiety and Stress
Senior dogs can develop anxiety as they age, especially if they experience cognitive decline, vision loss, or hearing loss.
Excessive licking can be a self-soothing behavior similar to nail-biting in humans. Triggers may include changes in routine, new environments, or separation from their owner.
Neurological Disorders
Neurological issues such as canine cognitive dysfunction (similar to dementia) can cause repetitive behaviors, including excessive licking.
These dogs may seem confused, pace, or struggle with sleep changes. The licking is often compulsive and not easily redirected.
Skin Allergies or Irritations
Older dogs can also develop allergies or skin conditions that cause itching and irritation. In response, they may lick their paws, legs, or other areas nonstop.
While allergies are common in all ages, they may worsen in older dogs due to a weakened immune system.
What to Do If Your Old Dog Is Licking Excessively
If your older dog is licking excessively, start by gently examining the area they focus on. Look for signs of redness, swelling, or wounds. If the licking is generalized, consider whether nausea, anxiety, or dental issues might be involved.
At home, you can try providing mental stimulation with toys or food puzzles to distract them. Regular grooming and skin care may also help if irritation is suspected.
Ensure your dog has a comfortable resting area, especially if arthritis pain may be a factor.
If stress or anxiety seems to be the cause, keeping a consistent routine and offering calming aids (like pheromone diffusers) may reduce licking behavior. However, if the licking persists, medical evaluation is essential.
When to Call or Visit Your Vet
You should contact your veterinarian if your dog’s licking is constant, causes hair loss, or results in open sores. Licking linked to nausea, weight loss, or changes in appetite also requires urgent veterinary care.
Dogs with sudden changes in behavior, such as compulsive licking paired with confusion, pacing, or disorientation, should be checked for neurological conditions.
Any sign of pain, bad breath, drooling, or difficulty eating warrants a dental exam. Skin infections, hot spots, and allergies also require prompt treatment to prevent worsening discomfort.

Key Takeaway
Excessive licking in older dogs should not be ignored. While sometimes it may be a mild behavioral quirk, it often signals underlying health issues such as dental disease, arthritis, nausea, anxiety, or skin irritation.
By monitoring your dog closely and seeking veterinary care when needed, you can ensure they stay comfortable and healthy in their senior years.
With proper attention, treatment, and care, many causes of excessive licking can be managed effectively, improving your dog’s quality of life.
