K9 foot lesions, treatment - cause - prevention

Why do dogs get lesions on their feet?

Dogs can develop lesions on their feet for various reasons. Some common causes include:

Infections:

  • Bacterial Infections: These can arise if a small wound on the paw becomes infected. Conditions like interdigital furunculosis, which are deep-set bacterial infections, can lead to painful lumps between the toes.

  • Fungal Infections: Yeasts and other fungi can cause infections in the moist areas between the toes.


Allergies:

  • Dogs can develop allergies to certain foods, environmental factors (like pollen or grass), or even substances they walk on. This can result in itchy, inflamed paws and can lead to secondary bacterial or fungal infections due to scratching or licking.


Parasites:

  • Fleas, ticks, and mites can cause lesions or irritation on the feet.


Trauma:

  • Cuts, abrasions, or foreign objects (like thorns or glass) can result in lesions. Dogs that run on rough or hot surfaces can also get burns or blisters.


Autoimmune Diseases:

  • Conditions like pemphigus or lupus can cause lesions on various parts of the body, including the feet.


Tumors:

  • Both benign and malignant tumors can form on a dog's paws. While not all lumps are cancerous, any new growth should be checked by a veterinarian.


Pododermatitis:

  • This is a general term for inflammation of the feet. It can be caused by many of the factors listed above.


Hormonal Disorders:

  • Conditions like hypothyroidism can lead to skin issues, including those affecting the paws.


Foreign Body Reaction:

  • Sometimes, foreign materials like plant awns, splinters, or other debris can embed in the foot, leading to a persistent inflammatory reaction.


Environmental Factors:

  • Cold weather can cause frostbite, and chemicals like de-icing salts can irritate a dog's paws. In contrast, hot pavements can cause burns.


If you notice lesions, limping, excessive licking, swelling, redness, discharge, or any other unusual signs related to

your dog's feet, it's essential to consult with a veterinarian. They can diagnose the underlying cause, recommend

appropriate treatments, and provide guidance on how to prevent future issues. How do I know if my dog has foot lesions?

To determine if your dog has foot lesions or any other problems with its feet, you'll need to perform a regular and

thorough check. Here's a guide to help you recognize foot lesions or related issues:

Visual Inspection:

  • Look at each paw, including between the toes. Look for any cuts, sores, swellings, lumps, or discoloration.

  • Check the nails for any signs of breakage, splitting, or overgrowth.

  • Look for any foreign objects like thorns, glass shards, or burrs.

  • If your dog has long hair, you might need to trim it back to get a good look.


Smell the Paws:

  • A foul odor can be a sign of infection.

Feel the Pads:

  • Gently palpate the pads. They should be smooth and free of cracks. If they're rough, your dog might have been walking on hot or rough surfaces.

  • While you're feeling around, check for any areas of warmth, which might indicate inflammation or infection.


Watch for Behavioral Signs:

  • Limping: This can indicate pain or discomfort in the foot.

  • Excessive Licking or Chewing: If your dog is constantly licking or chewing its feet, it could be trying to soothe irritation, itching, or pain.

  • Reluctance to Walk: If your dog seems hesitant to walk or stand, it might have foot pain.

  • Whining or Crying: If your dog yelps when a particular paw is touched, it may be in pain.


Swelling and Redness:

  • Check between the toes and around the foot for signs of inflammation.

Discharge:

  • Pus, blood, or any other unusual discharge can be a sign of infection or injury.


If you're unsure about what you're seeing, or if you suspect your dog has a foot problem, it's always best to

consult with a veterinarian. They can provide a thorough examination, accurately diagnose any issues, and

recommend appropriate treatments. Regularly checking your dog's paws is also a good practice; it can help you

catch and address potential problems early.

What is the worst thing that can happen if foot lesions are left untreated? If foot lesions in dogs are left untreated, they can lead to a variety of complications. The severity and nature of the

complications depend on the underlying cause of the lesion, but here are some potential negative outcomes:

  1. Deep Infections: A surface wound or lesion can become a gateway for bacteria, leading to deeper infections that can spread to the underlying tissues, bones, or even the bloodstream.

  2. Abscess Formation: Pockets of pus can form if infections are not addressed, leading to painful abscesses.

  3. Cellulitis: This is a painful condition where the skin and soft tissues become inflamed and infected.

  4. Septicemia: If an infection spreads to the bloodstream, it can lead to sepsis, a life-threatening condition that requires immediate medical attention.

  5. Chronic Pain and Discomfort: Persistent lesions can cause ongoing pain, which can affect the dog's quality of life and behavior.

  6. Lameness or Permanent Limping: Untreated lesions, especially those that become infected or lead to deeper tissue damage, can result in permanent limping.

  7. Spread of Diseases: If the lesion is caused by autoimmune diseases, tumors, or certain systemic infections, delaying treatment can result in the disease progressing or spreading.

  8. Behavioral Changes: Chronic pain or discomfort can lead to behavioral changes like increased aggression, anxiety, or depression.

  9. Tissue Necrosis: In severe cases, untreated lesions and infections can lead to tissue death, requiring surgical intervention or amputation.

  10. Potential for Malignancy: If the lesion is a tumor, delaying diagnosis and treatment can allow a potentially benign tumor to become malignant or allow a malignant tumor to metastasize.

  11. Aggravation from Self-Trauma: Dogs often lick, bite, or chew at uncomfortable areas. This self-trauma can exacerbate lesions and introduce new infections.

  12. Scarring: Even if the lesion eventually heals on its own, it might leave behind significant scarring, which can impact the function and appearance of the foot.

Given these potential complications, it's essential to consult with a veterinarian if you notice any foot lesions or

related symptoms in your dog. Early detection and treatment can prevent many of these severe outcomes and

ensure the best possible health and comfort for your pet.



What is the best way to prevent canine foot lesions? Preventing canine foot lesions involves a combination of regular care, environmental management, and

awareness of potential hazards. Here are some strategies to help minimize the risk:

  1. Regular Paw Checks: Examine your dog's paws frequently to catch and address problems early. Look for cuts, abrasions, foreign objects, swelling, and signs of infection.

  2. Paw Cleaning: After walks, especially in muddy or dirty environments, clean your dog's paws with a damp cloth. This removes debris and reduces the risk of infection.

  3. Trim Hair Between Pads: For breeds with long hair, trim the fur between the pads to prevent matting and accumulation of debris.

  4. Nail Trimming: Regularly trim your dog's nails to prevent overgrowth, which can lead to pain and abnormal walking patterns.

  5. Avoid Harsh Surfaces: When possible, keep your dog off hot pavements, icy roads, or rough terrains. These can cause burns, frostbite, or abrasions. If your dog is sensitive, consider protective dog booties.

  6. Address Allergies: If your dog has environmental or food allergies, work with your vet to manage them. This might include diet changes, medications, or allergen avoidance.

  7. Provide Proper Nutrition: A balanced diet supports overall health, including skin and paw health.

  8. Maintain Healthy Weight: Overweight dogs are more likely to experience foot and joint issues.

  9. Parasite Prevention: Use flea and tick preventatives as recommended by your veterinarian.

  10. Avoid Chemical Irritants: Be cautious about walking your dog in areas recently sprayed with pesticides, herbicides, or other chemicals. During winter, wash your dog's feet after walks to remove any de-icing chemicals or salts.

  11. Provide Proper Footwear: In harsh conditions, dog boots can protect against rough terrains, snow packed with ice-melting agents, and extremely hot surfaces.

  12. Environmental Enrichment: Ensure your dog has toys and activities to prevent boredom, which can lead to excessive licking or chewing of the paws.

  13. Regular Veterinary Check-ups: Routine vet visits can catch potential problems early, including those that might lead to foot issues.

  14. Moisturize Pads: If your dog's pads become dry and cracked, ask your vet for a recommendation on a safe moisturizer.

  15. Training: Train your dog to allow you to handle its paws. This makes inspections, cleaning, and treatments easier.

Remember that even with preventative measures, dogs can still occasionally experience foot issues due to their

active nature. Regular checks and prompt attention to any abnormalities are key to ensuring your dog's paws

remain healthy.


What is the best way to treat canine foot lesions? The best way to treat canine foot lesions depends on the underlying cause and severity of the lesions. However,

general steps and recommendations include:

  1. Consult a Veterinarian: Always consult with a veterinarian if you notice a foot lesion or any abnormalities on your dog's paws. They can provide a definitive diagnosis and recommend specific treatments.

  2. Clean the Area: Gently clean the affected foot with a mild antiseptic solution or saline (salt water). This helps prevent secondary infections.

  3. Topical Treatments:

    • Antibiotics or Antifungal Creams: Depending on whether the lesion is bacterial or fungal, your vet may prescribe a topical treatment.

    • Steroid Creams: For inflammatory conditions or allergies, a topical steroid may be prescribed to reduce swelling and itching.


Oral Medications:

  • In some cases, oral antibiotics, antifungals, or anti-inflammatory medications might be needed.

  • If allergies are the underlying cause, antihistamines or other allergy medications may be prescribed.

Protect the Foot:

  • Use a protective bootie or bandage to keep the area clean and to prevent your dog from licking or biting the lesion.

  • Ensure the bandage isn't too tight and check regularly for signs of swelling above or below the bandage.


  1. E-collar (Elizabethan collar): This cone-shaped collar prevents your dog from reaching its paws and can help in cases where the dog excessively licks or chews the lesion.

  2. Soaks and Compresses: Warm soaks or compresses with Epsom salts or medicated solutions can help with certain conditions, like interdigital cysts. Your vet will provide guidance if this is recommended.

  3. Surgery: In some cases, especially with tumors or deep abscesses, surgical intervention may be necessary.

  4. Dietary Supplements: Omega-3 fatty acids and other skin-health supplements can support skin healing and overall skin health.

  5. Avoidance: If an environmental allergen or irritant is the cause, try to identify and eliminate it. This could be anything from a specific type of grass or plant to household cleaning agents.

  6. Regular Follow-up: Ensure you follow up with your vet as recommended to check the healing progress and adjust treatments if necessary.

  7. Monitor for Secondary Issues: Watch for signs of secondary infections, increased pain, or other complications.

It's essential to address the underlying cause of the lesion to prevent recurrence. Whether it's an allergy, an

infection, or another issue, working with your vet to identify and manage the root cause will ensure the best

outcome for your dog.



Are certain breeds of dog more likely to get foot lesions?



Yes, certain dog breeds are more prone to specific health issues, including foot lesions, due to their genetic

predispositions, physical characteristics, and historical purposes. Here are some examples:

  1. Brachycephalic Breeds: Breeds like Bulldogs, French Bulldogs, and Boston Terriers have tightly spaced toes, which can create warm, moist environments. These conditions can increase the risk for interdigital cysts and infections.

  2. Hairy Breeds: Breeds with long hair between their toes, like Cocker Spaniels or some Terriers, can get matting and trapped debris, which can lead to infections or irritations.

  3. Working and Hunting Breeds: Breeds that historically worked in rough terrains, like German Shepherds, Golden Retrievers, and Labrador Retrievers, might be more prone to injuries, such as cuts or abrasions.

  4. Breeds with Allergies: Some breeds are more genetically predisposed to allergies, which can lead to foot lesions due to excessive licking and chewing. Breeds often associated with higher allergy risks include West Highland White Terriers, Boxers, Dalmatians, and Shar-Peis.

  5. Breeds with Autoimmune Disorders: Certain breeds are more likely to develop autoimmune skin disorders, which can manifest as foot lesions. For example, lupus, which can affect the skin and cause lesions, is more commonly reported in breeds like Shetland Sheepdogs, German Shepherds, and Collies.

  6. Large, Heavy Breeds: Giant breeds or heavy breeds, like Mastiffs or Saint Bernards, may experience pressure sores on their feet, especially if they lie down on hard surfaces frequently.

  7. Breeds with Specific Genetic Disorders: Some breeds have genetic predispositions to certain skin disorders. For instance, the Norwegian Lundehund can develop a condition called Lundehund Syndrome, which, among other symptoms, can cause foot lesions.


While these predispositions exist, it's crucial to remember that any dog, regardless of breed, can develop foot

lesions due to various external factors such as trauma, environmental irritants, or infections. Regularly

inspecting your dog's paws and providing preventative care can help mitigate risks. If you suspect any issues,

consult with a veterinarian for proper diagnosis and treatment.
