How to Spot & Treat Them
Welcome to the Dog Skin Guide!
Skin problems are common in dogs and can cause a lot of discomfort. This guide is here to help you understand what to look for, learn about common conditions, and find out how you can help your furry friend. Remember, this information is for educational purposes and not a substitute for professional veterinary advice.
Itching is often the main sign that something is wrong with your dog's skin. It's not just a bad habit – it usually means there's an underlying health issue that needs attention.
Understanding Symptoms
Recognizing the early signs of skin problems can help you get your dog the care they need sooner. Below are some common symptoms. If you notice any of these, especially if they are severe or persistent, it's best to consult your vet.
Itching (Pruritus)
Persistent scratching, licking, biting, or rubbing. This is the most common sign and can be caused by almost any skin condition, including allergies, parasites, or infections.
Hair Loss (Alopecia)
Patches of thinning hair or complete baldness. Can be due to parasites (like mange), fungal infections (ringworm), allergies, or excessive licking.
Red Skin (Erythema)
Skin appears pinker or redder than usual, often inflamed. Common with allergies, infections, and irritations.
Flaky Skin / Dandruff-like Scales
Dry, flaky skin, sometimes looking like dandruff. Can be a sign of infection (bacterial or fungal), parasites, or underlying metabolic issues.
Bumps, Pimples, or Pustules
Small raised lesions, some may contain pus. Often indicates a bacterial infection (pyoderma) or parasitic issue like mange.
Wounds, Sores, or Scabs
Open skin, raw areas, or crusty scabs. Can result from self-trauma (scratching/licking) or be a primary sign of infection or other conditions.
Bad Odor
A musty, yeasty, or generally unpleasant smell from the skin or ears. Often associated with yeast or bacterial infections.
Thickened or Darkened Skin
Skin may become tough, leathery (lichenification or "elephant skin"), or change to a darker color in chronic cases. Often seen with long-standing allergies or yeast infections.
Paw Chewing or Licking
Excessive focus on the paws. A very common sign of allergies (environmental or food).
Ear Problems
Redness, swelling, discharge, bad odor, or head shaking/scratching at ears. Often linked to allergies, yeast, or bacterial infections.
Sudden Bumps or Welts (Hives)
Raised patches on the skin that appear quickly. Usually an acute allergic reaction (e.g., to an insect bite or new medication).
If your dog shows any of these signs, especially if they are severe, sudden, or don't improve quickly, please consult your veterinarian for an accurate diagnosis and treatment plan.
Common Skin Conditions
This section provides information about common skin problems in dogs. Remember, a vet is the only one who can diagnose your dog.
🦠 Parasitic Skin Problems
Parasites like fleas, ticks, and mites are very common causes of skin issues in dogs.
Flea Allergy Dermatitis (FAD)
What it is:
The most common allergy in dogs, caused by an overreaction to flea saliva. Even a few bites can trigger intense itching in sensitive dogs.
Signs:
- Intense itching, especially around the tail base, rump, and back legs ("flea triangle").
- Excessive chewing, biting, licking.
- "Hot spots" (red, moist, inflamed skin patches).
- May be hard to see actual fleas due to intense grooming.
How Vets Diagnose:
Usually based on signs and if the dog improves with strict flea control. Skin or blood allergy tests can confirm but aren't always needed.
Treatment Note:
Strict, year-round flea control is essential. Vets may prescribe medication for itching and any secondary infections. Always consult your vet.
Mange (Sarcoptic & Demodectic)
Sarcoptic Mange (Scabies):
Causes: Tiny Sarcoptes scabiei mites. Highly contagious to other dogs and can pass to humans.
Signs: Sudden, severe itching. Bumps on ear edges, elbows, hocks, belly, turning to red bumps, scabs, thick yellow crusts, hair loss. Can lead to very thick skin and weight loss in chronic cases.
Diagnosis: Deep skin scrapings (mites can be hard to find). Skin biopsies or PCR may be useful in negative cases. Especially true in scabies, where false-negative scrapings are common.
Demodectic Mange (Red Mange):
Causes: Overgrowth of Demodex canis mites (normal skin inhabitants). Often linked to genetics or a weak immune system. Not usually severely itchy in localized forms.
Signs: Patches of hair loss (often around face/eyes in localized form). Widespread form has more hair loss, red/inflamed skin ("red mange"), often with secondary bacterial infections.
Diagnosis: Deep skin scrapings to see mites.
Important: Widespread demodectic mange is often genetic. Affected dogs and their parents should not be bred.
Treatment Note:
Requires specific medications from your vet. All dogs in the household may need treatment for sarcoptic mange. Environmental cleaning is also important. Always consult your vet.
🌿 Allergic Skin Problems
Allergies are a very common cause of long-lasting skin issues in dogs.
Atopic Dermatitis (Environmental Allergies)
What it is:
A long-term, inherited allergic skin disease. Dogs react to common environmental things like pollens, dust mites, or molds. Often gets worse over time ("atopic march").
Signs:
- Intense itching, sneezing, watery eyes, paw chewing.
- Rashes, inflamed skin, excessive grooming/licking.
How Vets Diagnose:
Based on signs, history, and ruling out other itchy conditions. Allergy tests (skin or blood) can help find triggers.
Note: Atopic dermatitis is a lifelong condition with no cure, requiring ongoing management. Repeated infections can lead to antibiotic resistance.
Treatment Note:
Management involves reducing itch, controlling inflammation, and sometimes allergy shots (immunotherapy). Vets will create a long-term plan. Always consult your vet.
Food Hypersensitivity (Food Allergies)
What it is:
An allergic reaction to ingredients in food, usually proteins (chicken, beef, etc.).It can appear at any age, even with long-term foods.
Signs:
- Skin irritation and scratching (main signs).
- Can also cause stomach problems (diarrhea, vomiting, gas).
- Symptoms usually don't change with seasons.
How Vets Diagnose:
The best way is an "elimination diet trial" for 8-12 weeks, using a special "novel protein" or "hydrolyzed protein" diet. Blood tests are generally not accurate. Home-prepared diets for trials must be balanced by a vet nutritionist. Strictness is key – no other foods or treats.
Role of Furry Green Gently Processed Fresh Food:
For elimination trials and long-term management, diets using novel proteins from fresh, whole food sources can be beneficial. Furry Green's Hypoallergenic recipes contain novel proteins such as venison and ostrich, which dogs are less exposed to. These proteins are less likely to contain hidden allergens sometimes found in kibble and canned foods.
Here are our Hypoallergenic products:
Hypoallergenic Combo for dogs (Lamb x Duck x Venison)
Venison & Purple Sweet Potato
Ostrich & Potato
Lamb + Bell Pepper
Duck & Sweet Potato
Consult your veterinarian or a veterinary nutritionist to ensure any diet is complete and balanced for your dog's specific needs.
Hives (Urticaria)
What it is:
Hives (urticaria) are typically an acute allergic reaction caused by things like:
- Insect bites (e.g. bees, ants)
- Vaccinations or medications
- Food ingredients
- Contact allergens (e.g. chemicals, plants)
Signs:
- Raised bumps or welts on the skin, making fur stand up.
- Sometimes swelling around the eyes.
Treatment Note:
Treatment depends on severity and whether the dog is showing systemic signs (e.g. facial swelling, breathing difficulty).
1. First-Line Treatment (for mild to moderate cases):
Antihistamines:
Diphenhydramine (Benadryl) is commonly used.
Must be dosed based on veterinary guidance (not safe for all dogs or situations).
Corticosteroids:
Used if antihistamines don’t control signs quickly or the reaction is more moderate.
Used if antihistamines don’t control signs quickly or the reaction is more moderate.Prednisone or an injectable corticosteroid (like dexamethasone) may be given by a vet.
2. Supportive Care:
Cool water rinses or compresses may soothe discomfort, but not a treatment for urticaria. Hypoallergenic shampoo may reduce contact allergens in recurrent cases.
3. Severe or Life-Threatening Cases (Anaphylaxis):
Emergency treatment: epinephrine, IV fluids, oxygen, and hospitalization
Signs include: vomiting, diarrhea, collapse, difficulty breathing
🍄 Fungal Skin Infections
Fungi like ringworm or yeast can cause significant skin problems.
Dermatophytosis (Ringworm)
What it is:
Caused by fungi that infect skin, hair, and nails. Young animals are more susceptible. Can spread to humans.
Signs:
- Round patches, often with hair loss, flaky skin, redness, and scabs.
- Can look different and be mistaken for other issues.
How Vets Diagnose:
Fungal culture (growing samples) is common. Looking at hairs under a microscope or PCR tests can also be used.
Treatment Note:
Often involves topical (creams, dips) and oral antifungal medicines. Environmental cleaning is crucial. Always consult your vet.
Malassezia Dermatitis (Yeast Infection)
What it is:
Overgrowth of Malassezia yeast (normally on skin). Often secondary to other issues like allergies, hormone problems, or in skin folds/humid weather.
Signs:
- Intense itching, redness, strong musty/bad smell.
- Greasy/flaky patches, thick skin (lichenification "elephant skin"), dark skin.
- Ongoing or returning ear infections.
How Vets Diagnose:
Looking at skin samples under a microscope (cytology). Fungal cultures can also confirm.
Treatment Note:
Usually a mix of topical (medicated shampoos, wipes) and oral antifungal treatments. Addressing underlying causes is key. Always consult your vet.
🔬 Bacterial Skin Infections (Pyoderma)
Bacterial infections are common, often occurring as a secondary problem.
Superficial Pyoderma
What it is:
Usually caused by Staphylococcus bacteria. Triggers include scratching, allergies, or a weak skin barrier.
Signs:
- Red, itchy skin, round scabs, flaky skin, patches of hair loss.
- Pimple-like bumps (pustules).
- "Hot spots" (wet, inflamed areas from licking/scratching).
How Vets Diagnose:
Seeing bacteria and inflammation in skin samples under a microscope. Vet exam and history help find underlying causes.
Treatment Note:
Often involves topical treatments (antiseptic shampoos/sprays) and sometimes oral antibiotics. Addressing the underlying cause is crucial. Always consult your vet.
Deep Pyoderma
What it is:
More serious bacterial infections going deeper into skin layers. Often a complication of long-term issues like allergies, parasites, or hormone problems.
Signs:
- Swelling, oozing sores, pain, low energy, not eating.
- Skin might become darker and much thicker in long-term cases.
- Specific types include infections between toes, acne, lick granulomas.
How Vets Diagnose:
Seeing bacteria/inflammation in samples. Bacterial culture and sensitivity testing is very important to choose the right antibiotic, especially due to antibiotic resistance risk.
Treatment Note:
Requires appropriate antibiotics, often for a longer duration. Addressing the underlying cause is critical. Always consult your vet.
Care & Prevention Strategies
Proactive care can significantly reduce the risk of skin problems and help manage existing conditions. Here are some key strategies:
🧼 Regular Grooming & Hygiene
- Brushing: Regular brushing (daily for some breeds, weekly for others) helps remove loose hair, dirt, and dander, and distributes natural skin oils. This can prevent matting, which can trap moisture and lead to infections.
- Bathing: Bathe your dog as needed, but not too frequently, as this can strip natural oils. Use a veterinarian-recommended or gentle, hypoallergenic dog shampoo. If your dog has a specific skin condition, your vet may prescribe a medicated shampoo.
- Paw Care: Check paws regularly for irritants, cuts, or signs of licking/chewing. Keep paw fur trimmed if it tends to collect debris.
- Ear Cleaning: Clean ears as recommended by your vet, especially for breeds prone to ear infections. Use a proper canine ear cleaner.
🥗 Nutrition & Diet
- High-Quality Diet: Feed your dog a balanced, high-quality commercial dog food appropriate for their age, breed, and activity level. Good nutrition is the foundation of healthy skin and coat.
- Essential Fatty Acids: Omega-3 and Omega-6 fatty acids can support skin health. These are often included in good quality foods, or your vet might recommend a supplement.
- Allergen Avoidance: If your dog has known food allergies, strictly avoid those ingredients. Read labels carefully on all food and treats.
🛡️ Parasite Control
- Year-Round Prevention: Use effective flea and tick preventatives year-round, as recommended by your veterinarian. Even indoor pets can be exposed.
- Environmental Control: Regularly wash your dog's bedding in hot water, vacuum frequently, and treat your home and yard if a flea infestation occurs.
🏠 Environmental Management
- Clean Living Space: Keep your dog's living environment clean. Wash bedding, blankets, and toys regularly.
- Avoid Irritants: Be mindful of potential irritants in your home and yard, such as harsh cleaning chemicals, certain fabrics, or lawn treatments.
- Manage Allergens: If your dog has environmental allergies, work with your vet to identify and minimize exposure to triggers like pollen, dust mites, or molds. This might involve using air purifiers or wiping your dog down after walks.
🩺 Regular Veterinary Check-ups
Routine wellness exams allow your vet to spot early signs of skin issues and discuss preventative care tailored to your dog's specific needs and lifestyle.

When to Call the Vet
While some minor skin irritations might resolve on their own with good home care, many skin problems require professional veterinary attention for accurate diagnosis and effective treatment. Don't hesitate to contact your vet if you notice any of the following:
- Persistent Symptoms: Itching, scratching, licking, or chewing that lasts for more than a few days, or seems to be getting worse despite home care.
- Sudden or Severe Onset: If symptoms appear suddenly and are intense (e.g., widespread hives, severe redness, acute pain).
- Spreading Lesions: Any rashes, bumps, hair loss patches, or sores that are increasing in size or number.
-
Signs of Infection:
- Pus or discharge from the skin or ears.
- A foul or unusual odor from the skin or ears.
- Skin that is hot to the touch.
- Fever, lethargy, or loss of appetite accompanying skin issues.
- Pain or Significant Discomfort: If your dog seems to be in pain, is yelping when touched, or is unusually agitated or withdrawn due to their skin.
- Changes in Skin Texture or Color: Such as thickening, crusting, scaling, or darkening of the skin.
- Non-Healing Sores: Any open wounds or sores that aren't healing or are getting worse.
- Bleeding or Oozing: From any skin lesions.
- If You're Unsure: It's always better to err on the side of caution. If you're concerned about your dog's skin, a vet visit can provide peace of mind and ensure your pet gets the care they need promptly.
Early veterinary intervention can often prevent minor issues from becoming more serious and can lead to quicker relief for your dog.
