It’s a familiar scene for many dog owners: you notice your furry friend diligently licking or even chewing at their paws. Perhaps it’s occasional and seemingly harmless, or maybe it’s becoming more frequent and intense, even to the point of causing you concern. You might have tried to distract them with their favorite toy or a cheerful call of their name, but the paw-focused behavior persists. This raises a common question among pet parents: Why Do Dogs Chew Their Paws?
Understanding the reasons behind this behavior is crucial for ensuring your dog’s well-being. According to Dr. Valentina Henao, a veterinarian and medical director at Veterinary Emergency Group (VEG) in Miami, paw licking and chewing in dogs can stem from a variety of causes. These range from relatively minor issues such as fleas or allergies to more significant problems like injuries or underlying pain.
Let’s delve into the most common reasons why dogs engage in paw licking and chewing, and explore potential treatments to help your canine companion.
Unpacking the Paw-Chewing Puzzle: 5 Common Causes
Occasional paw licking is often a normal part of canine grooming and exploration. Dogs might lick their paws to clean them after a walk, as a form of self-soothing, or simply out of curiosity. However, when this behavior becomes excessive – meaning it’s frequent, persistent despite distractions, and potentially causing self-harm – it’s time to investigate further.
Here are five key reasons why your dog might be obsessively licking or chewing their paws:
1. Injuries and Pain: When Paws Hurt
While a casual lick might just be grooming, aggressive and focused chewing or licking at a paw can be a strong indicator of pain or discomfort. If you notice your dog favoring a leg, limping, struggling with stairs, or showing reduced activity levels alongside paw chewing, pain is a likely culprit. Potential sources of pain in the paws include:
- Cuts and Wounds: Sharp objects on walks or even rough play can lead to cuts on paw pads or between toes.
- Foreign Objects: Thorns, splinters, or glass shards can become lodged in the paws, causing irritation and pain.
- Insect Stings or Bites: Bee stings, wasp stings, or insect bites can be painful and cause localized reactions. Dr. Henao emphasizes checking for embedded stingers, especially in cases of suspected stings, as these can trigger allergic reactions.
- Bruises or Sprains: Just like humans, dogs can bruise or sprain their paws from missteps or overexertion.
If you suspect an injury, carefully examine your dog’s paws for visible wounds, swelling, redness, or foreign objects. For any suspected injury or persistent pain, consulting your veterinarian is essential for proper diagnosis and treatment.
2. Pesky Parasites: Fleas and Ticks
Fleas and ticks are common external parasites that can cause significant itching and irritation in dogs, leading them to lick, bite, and chew at their skin, including their paws. These pests can thrive in various environments your dog frequents, such as bedding, carpets, grassy areas, and wooded trails.

Detecting fleas often involves a visual inspection. Look for small, fast-moving dark insects in your dog’s fur and tiny black specks known as “flea dirt” (flea droppings). Ticks, on the other hand, tend to attach themselves firmly to the skin. Common tick hiding spots include between the toes, under the legs, and behind the ears.

If you find a tick, use tweezers to carefully remove it, grasping it as close to your dog’s skin as possible. Ensure you remove the entire tick, including the mouthparts, to prevent skin infections. Tick spoons are also available for easier and safer removal.
Fortunately, flea and tick infestations are readily preventable and treatable with various medications. Consult your veterinarian about appropriate flea and tick preventatives, including prescription and over-the-counter options, to protect your dog.
3. Allergic Reactions: Environmental and Food Triggers
Allergies are a frequent culprit behind excessive paw licking and chewing. Dr. Henao explains that allergic reactions can manifest almost anywhere on a dog’s body, including the skin and paws. Allergies can trigger skin infections, hot spots, and ear infections, all of which can contribute to paw irritation and chewing. Identifying the specific allergen can be complex, as they can originate from various sources:
- Environmental Allergens: Pollen, dust mites, mold, and grass are common environmental allergens that can cause seasonal or year-round allergic reactions in dogs.
- Food Allergens: Certain food ingredients, such as beef, chicken, dairy, or wheat, can trigger food allergies in sensitive dogs.
- Contact Allergens: Irritants like certain shampoos, cleaning products, or lawn chemicals can cause allergic reactions upon skin contact.

Managing allergies often requires a multi-faceted approach. Veterinarians may recommend allergy medications, allergy injections (immunotherapy), specialized hypoallergenic diets, topical treatments, and medicated shampoos to alleviate symptoms and address the underlying allergy. In cases of secondary infections caused by allergies, topical or oral medications and an Elizabethan collar (recovery cone) might be necessary to prevent further licking and allow healing.
4. Arthritis and Joint Pain: Especially in Senior Dogs
Arthritis, a degenerative joint condition, is particularly common in older dogs. While arthritis is often associated with larger joints like hips and elbows, it can also affect the smaller joints in the toes and paws. As joint cartilage breaks down, it leads to pain, inflammation, and reduced mobility, which can cause dogs to lick and chew at their paws in an attempt to soothe the discomfort.
Fortunately, various strategies can help manage arthritis pain and improve your dog’s comfort and mobility:
- Veterinary-Approved Supplements: Glucosamine and chondroitin supplements, or joint-support diets, may be recommended by your vet to support joint health.
- Weight Management: Maintaining a healthy weight is crucial for dogs with arthritis, as excess weight puts additional stress on painful joints.
- Controlled Exercise and Physical Therapy: Low-impact exercises and physical therapy can help maintain joint mobility and reduce pain.
- Pain and Anti-inflammatory Medications: Depending on the severity of arthritis, your veterinarian may prescribe pain relievers and anti-inflammatory medications to manage pain and improve quality of life.
5. Behavioral and Psychological Factors: Stress and Anxiety
Just like humans, dogs can experience behavioral and mental health issues that can manifest physically. Dr. Henao points out that even after ruling out medical causes like allergies or infections, some dogs may continue to lick and chew their paws due to underlying behavioral or psychological factors. These can include:
- Anxiety and Stress: Changes in routine, separation anxiety, loud noises, or new environments can trigger anxiety and stress in dogs, leading to compulsive behaviors like paw licking.
- Boredom: Lack of mental and physical stimulation can lead to boredom, which may manifest as excessive licking or chewing as a way to self-entertain.
- Habit: In some cases, paw licking can become a learned habit, even after the initial trigger (like an injury or allergy) has resolved.
Addressing behavioral paw licking often requires identifying and managing the underlying stress or anxiety triggers. Veterinary behaviorists or certified trainers can help develop strategies to modify behavior, reduce anxiety, and provide appropriate mental and physical enrichment for your dog.
When Paw Chewing Requires a Vet Visit
While occasional paw licking might be normal, certain signs warrant prompt veterinary attention. Dr. Henao advises seeking veterinary care as soon as possible if you observe any of the following in conjunction with paw licking or chewing:
- Bleeding from the paws
- Swollen paws
- Limping or lameness
- Pus or discharge from the paws (indicating infection)
- Whimpering, wincing, or signs of pain when the paws are touched
Prompt veterinary consultation is crucial to determine the underlying cause of your dog’s paw chewing and initiate appropriate treatment. Dr. Henao cautions that untreated paw licking can escalate into a more significant problem, potentially leading to bacterial infections of the paws, known as pododermatitis. Pododermatitis can be painful and challenging to treat, highlighting the importance of early intervention.
By paying close attention to your dog’s behavior and seeking timely veterinary advice when needed, you can effectively address paw chewing and ensure your furry companion’s paws remain healthy and happy.
