Why Do Dogs Chew Their Paws? 8 Reasons (And When to Worry)

Your dog won't stop chewing his paws. They're red, raw, and you're worried. Here's what's actually causing it—and how to help.

If you like this kind of honest, obsessive dog-behavior breakdown, there’s more of it over on the GREET Dog blog.

Scout's Raw, Red Paws

I noticed it on a Wednesday evening.

Scout was lying on his bed, chewing his front paw. Not just licking—chewing. Biting at it like he was trying to get something off.

"Scout, what's wrong?"

He looked up at me with those big, worried Australian Shepherd eyes, then immediately went back to chewing. Obsessively. Frantically.

I checked his paw. It was red. Raw. The fur between his toes was wet and stained brown from constant licking and chewing.

My first thought: "Did he step on something? Is there a cut? A thorn?"

I examined every inch of his paw. Nothing. No visible injury. No foreign object. Just red, irritated skin.

But he wouldn't stop. All evening, he kept chewing. By bedtime, his paw looked even worse.

The next morning, I Googled: "Why do dogs chew their paws?" "Why is my dog biting his paws?" "Dog licking paws remedies."

What I discovered was that paw chewing is rarely simple. It's not just one thing. It could be allergies, anxiety, pain, infection, parasites, or a combination of all of the above.

After three vet visits, two rounds of medication, and a lot of trial and error, I finally figured out what was causing Scout's paw chewing—and how to stop it.

Here's everything I learned about why dogs chew their paws, when it's serious, and what actually works to help them stop.

Paw Licking vs. Paw Chewing: What's the Difference?

Before we dive into causes, let's clarify the difference between licking and chewing—because they often indicate different problems.

Paw Licking:

• Gentle, repetitive licking
• Usually focused on one or two paws
• Can be soothing behavior
• Common with anxiety or mild irritation

Paw Chewing/Biting:

• Aggressive, intense gnawing or biting
• Often targets specific spots (between toes, paw pads)
• More likely to cause visible damage (redness, rawness, hair loss)
• Usually indicates stronger discomfort or irritation

Scout wasn't just licking—he was chewing. That told me something was actively bothering him.

8 Reasons Dogs Chew Their Paws

1. Allergies (The Most Common Cause)

This was Scout's problem.

Dogs can be allergic to:

• Environmental allergens: Pollen, grass, dust mites, mold
• Food allergies: Chicken, beef, dairy, wheat, soy
• Contact allergies: Cleaning products, lawn chemicals, carpet treatments

Why allergies cause paw chewing:

When dogs have allergies, their paws are one of the first places to show symptoms. Why? Because paws come into direct contact with allergens, and allergens can also make their whole body itchy—but paws become the easiest place to fixate on.

Signs it's allergies:

• Chewing happens seasonally
• Multiple paws affected
• Red, inflamed skin between toes
• Brown staining on paws
• Other symptoms: itchy ears, face rubbing, skin rashes
• Worsens after walks or being outside

What worked for Scout:

After allergy testing, we discovered he was reacting to grass and pollen. During allergy season, I rinse his paws with water after every walk. And when I’m looking at the food side too, I’d rather simplify that first than keep guessing forever → Vital Essentials Dog Food

2. Skin Infections (Bacterial or Yeast)

When dogs chew their paws constantly, they create a moist, warm environment between their toes—perfect for infections.

Types of infections:

Bacterial infections:

• Often secondary to allergies or injuries
• Cause redness, swelling, pus, or oozing
• May have a foul odor

Yeast infections:

• Common in dogs with allergies
• Distinctive "Frito feet" or "corn chip" smell
• Cause intense itching and redness
• Often affect skin folds and between toes

Signs it's an infection:

• Strong odor
• Visible discharge or pus
• Swelling or warmth in the paw
• Pain when you touch the paw
• Skin looks crusty, scaly, or oozing

Treatment:

Infections need real treatment, not guessing. If I were trying to get oriented fast on the health side while waiting on or working with a vet, this is one of the first places I’d look → Pet MD

If the smell part sounds familiar, this one pairs really well with that too → Why Do Dogs’ Paws Smell Like Fritos?

3. Parasites (Fleas, Ticks, Mites)

Parasites can cause intense itching that leads to obsessive paw chewing.

Common culprits:

• Fleas: Even one bite can set off a huge reaction
• Ticks: Can embed between toes
• Mites: Mange mites can cause severe itching

Signs it's parasites:

• Visible fleas or flea dirt
• Sudden onset of chewing
• Scratching other parts of the body too
• Hair loss or scabs

And if you think fleas might be part of it, this article fits hand-in-glove with that → Why Do Dogs Get Fleas?

4. Injuries or Foreign Objects

Sometimes paw chewing is a response to plain physical discomfort.

Common causes:

• Cuts or abrasions: From rough surfaces, glass, sharp rocks
• Thorns or splinters: Embedded in paw pads or between toes
• Broken nails: Painful and easy to irritate
• Burns: Hot pavement in summer or chemicals in winter
• Insect stings: Bee or wasp stings on paws

Signs it's an injury:

• Sudden onset after a walk or outdoor activity
• Focused on one specific paw
• Limping or favoring one leg
• Visible wound, swelling, or bleeding
• Dog yelps or pulls away when you touch the paw

What to do:

Carefully examine the paw. Look between toes, check paw pads, inspect nails. If you find something obvious, deal with that first. If you can’t, or it looks worse fast, don’t drag it out.

5. Anxiety or Boredom (Behavioral Causes)

This was part of Scout's issue too.

Dogs with anxiety often develop compulsive behaviors—and paw chewing is one of them.

Why anxiety causes paw chewing:

Chewing releases endorphins that provide temporary relief from stress. It becomes a self-soothing behavior, similar to humans biting their nails or picking at their skin.

Signs it's anxiety or boredom:

• Chewing happens during specific situations
• No clear physical cause
• Dog seems restless, paces, or shows other anxiety signs
• Chewing worsens when understimulated
• Other compulsive behaviors show up too

Common triggers:

• Separation anxiety
• Changes in routine or environment
• Lack of exercise or mental stimulation
• Stressful situations

What helped Scout:

Once we realized the physical side wasn’t the whole story, I started treating the stress and boredom side like a real issue too. That meant more movement, more structure, and more enrichment instead of just telling him to stop. This is where I’d usually start → KONG Dog Toys and Outward Hound Dog Puzzles and Toys

6. Arthritis or Joint Pain

This is more common in senior dogs but can happen at any age.

Why joint pain causes paw chewing:

Dogs with arthritis or joint pain might lick or chew their paws as a way to cope with discomfort. The paw isn't always the actual source of the pain—but dogs often focus there anyway.

Signs it's arthritis:

• Older dog
• Stiffness, especially after resting
• Difficulty getting up, climbing stairs, or jumping
• Reluctance to walk or exercise
• Chewing happens more after activity

7. Dry Skin or Cracked Paw Pads

Environmental factors can irritate paws enough to trigger chewing.

Common causes:

• Winter weather: Cold, dry air and salt
• Summer heat: Hot pavement
• Over-bathing: Strips natural oils
• Harsh cleaning products: Irritate sensitive pads

Signs it's dry skin:

• Visible cracks or roughness on paw pads
• Dry, flaky skin
• Seasonal pattern
• No major signs of infection

Treatment:

8. Hormonal Imbalances

Rare, but possible.

Conditions that can show up through skin and paw issues:

• Hypothyroidism: Can cause skin issues and itching
• Cushing's disease: Can affect skin health too

Signs it might be hormonal:

• Other symptoms: weight gain, hair loss, lethargy, excessive thirst
• Chronic skin issues that don't respond normally
• Middle-aged to senior dog

What Does It Mean If My Dog Chews on His Paws?

Short answer: Something is bothering him.

Paw chewing is always a symptom, never a standalone behavior.

Your dog isn't chewing his paws for fun. He's trying to relieve discomfort—whether that's physical or psychological.

The challenge is figuring out what is bothering him. And sometimes, it's more than one thing.

Scout's paw chewing was caused by both allergies and anxiety. We had to address both to stop it.

When Should I Worry About My Dog Chewing His Paws?

See your vet if:

• Paws are red, raw, or bleeding
• There's visible swelling, discharge, or pus
• Your dog is limping or won't put weight on the paw
• Chewing is constant and obsessive
• There's a foul odor
• Home remedies haven't helped after 1-2 weeks
• Other symptoms appear
• Your dog is chewing so much he's damaging the skin

Don't wait if you're concerned. Chronic paw chewing can turn into a much bigger mess fast.

My Dog Keeps Licking His Paws and They Are Red

This is a sign of active inflammation or infection.

What causes red paws:

• Allergies: Environmental or food allergies
• Infection: Bacterial or yeast infection from constant moisture
• Chemical irritation: Contact with harsh cleaners or lawn treatments
• Self-trauma: The licking itself keeps making it worse

What to do immediately:

1. Stop the licking: Use a cone or protective barrier
2. Clean the paws: Rinse with lukewarm water
3. See your vet: Red, inflamed paws need real evaluation

Don't let this just keep rolling. Red paws can turn into infection territory fast.

Why Does My Dog Chew His Paws at Night?

Nighttime paw chewing is really common and usually points to one of a few things:

1. Anxiety or Stress

Dogs with anxiety often get worse at night when the house is quiet and they have nothing else to focus on.

2. Allergies or Itching Worsens at Night

Allergy symptoms can feel worse once the day slows down. Plus, whatever they walked through is still sitting on their paws if you didn’t rinse it off.

3. Boredom

An under-stimulated dog can absolutely turn nighttime into chew-my-own-feet o’clock.

What helps:

• Rinse paws before bed
• Evening exercise to tire them out
• Calming support
• Mental enrichment before bed

How to Stop Dog from Licking Paws: Home Remedies

Important note: Home remedies can help with mild paw chewing. If your dog has severe symptoms, don’t guess.

Here's what actually helped Scout once we knew what we were dealing with:

1. Paw Rinses After Walks

Why it works: Removes allergens before they keep irritating the skin.

How to do it: Fill a shallow container with lukewarm water. Dip each paw for 30 seconds. Pat dry thoroughly.

2. Apple Cider Vinegar Soak (For Yeast)

Why it works: Can help with mild yeast overgrowth.

How to do it: Mix 1 part apple cider vinegar with 1 part water. Soak paws for 5 minutes. Pat dry completely.

Warning: Don’t use on open wounds or really raw skin.

3. Coconut Oil

Why it works: Helps with dry paw pads and irritated skin.

How to do it: Apply a small amount to paw pads. Massage in gently.

4. Epsom Salt Soak

Why it works: Helps reduce inflammation and soothe irritated skin.

How to do it: Dissolve Epsom salt in warm water. Soak paws for 5-10 minutes. Dry thoroughly.

5. Protective Booties

Why it works: Keeps allergens, chemicals, or rough surfaces off the paws during walks.

6. Elizabethan Collar (Cone)

Why it works: Stops the chewing long enough for the skin to calm down and heal.

7. Increase Exercise and Mental Stimulation

Why it works: Reduces anxiety and boredom, which are huge triggers for compulsive chewing.

This is usually where I’d start instead of hoping the behavior somehow disappears on its own → KONG Dog Toys, Outward Hound Dog Puzzles and Toys, and for better daily movement Ruffwear Dog Harnesses

8. Omega-3 Supplements

Why it works: Helps support skin health and reduce inflammation over time.

Treatment for Dog Biting Paws (Veterinary Options)

If home remedies aren't cutting it, your vet may recommend:

For Allergies:

• Antihistamines
• Cytopoint injections
• Apoquel
• Immunotherapy
• Food trials

For Infections:

• Antibiotics
• Antifungal medication
• Medicated shampoos
• Topical treatments

For Anxiety:

• Calming supplements
• Prescription anxiety medication
• Behavior modification
• Pheromone diffusers

For Pain or Arthritis:

• Pain medication
• Joint supplements
• Physical therapy

Why Is My Female Dog Biting Her Paws?

Female dogs deal with all the same main causes as males, but there’s one extra angle sometimes:

Hormonal fluctuations:

• Some unspayed females get more anxious or more compulsive during heat cycles
• Pregnancy or false pregnancy can change behavior a lot
• Post-spay hormonal shifts can temporarily affect skin and behavior too

If the timing lines up with a heat cycle or a recent spay, that’s worth mentioning to your vet.

Dog Licking Paws Remedies: What Actually Works

3. Paw rinses after every walk: Huge help for environmental allergies
4. Cone during healing: Break the chewing cycle
5. Increase exercise and enrichment: Reduced the stress side a lot
6. Consistent routine: Dogs with anxiety do way better with predictability
7. Patience: This wasn’t fixed overnight

What didn't work:

• Yelling at him to stop

FAQs About Dogs Chewing Their Paws

Q: Is it normal for dogs to lick their paws occasionally?

A: Yes, occasional paw licking is normal grooming behavior. It becomes a problem when it's frequent, obsessive, or causing visible damage.

Q: Can I use human antibiotic cream on my dog's paws?

A: No. A lot of human products are not meant for dogs. Stick with vet-approved stuff.

Q: How long does it take for paw chewing to stop?

A: Depends on the cause. Allergies can take weeks to settle down. Infections can improve within a week or two with treatment. Anxiety-driven chewing can take much longer.

Q: Should I stop my dog every time I see him licking his paws?

A: Not by just scolding him. Redirect instead. If he’s damaging the skin, use a cone and handle the actual cause.

Q: Can food allergies cause paw chewing?

A: Yes. Food allergies often show up through itchy paws, ears, and skin.

Q: Why do dogs chew the inside of their paws between the toes?

A: That area is super sensitive and really prone to allergies, moisture buildup, and yeast issues.

Q: Is paw chewing worse in certain seasons?

A: Yes. Spring and summer are brutal for environmental allergies. Winter can wreck paws too because of cold air and salt.

Q: Can I give my dog Benadryl for paw licking?

A: Ask your vet first. It can help some dogs, but dosage matters and it’s not the right answer for every case.

Q: What if my dog only chews one paw?

A: That usually points more toward a localized problem—injury, foreign object, or one specific irritated spot.

Q: Will my dog outgrow paw chewing?

A: Usually not. Left alone, it usually gets worse, not better.

The Bottom Line on Paw Chewing

After the vet visits and the trial and error with Scout, here's what I learned:

Paw chewing is never "just a habit." It’s information. It’s your dog telling you something is off—physically, emotionally, or both.

Scout's chewing came from a mix of environmental allergies and anxiety. We had to handle both. Once we did, the paws finally started calming down.

It took time. It took consistency. And it definitely wasn’t fixed by just trying to stop the chewing itself.

If your dog is chewing his paws, don’t sit on it. The longer it keeps going, the harder it gets to untangle.

Your dog isn’t being dramatic. He’s trying to deal with something the only way he knows how.
