Quick Answer:
Dog skin tags are small, benign growths that hang from the skin by a thin stalk. They're soft, flesh-colored, and usually harmless. While skin tags don't require removal unless they're causing problems, any new growth should be checked by a vet to rule out warts, moles, or cancerous tumors.
When to See a Vet Immediately:
If a growth is rapidly growing, changing color, bleeding, ulcerated, firm/hard, or if your dog seems bothered by it, schedule a vet appointment promptly. These could be signs of something more serious than a simple skin tag.
What Are Skin Tags on Dogs?
Skin tags, medically known as acrochordons or fibroepithelial polyps, are small, benign growths that develop on the skin's surface. They're essentially overgrowths of skin cells and collagen fibers surrounded by a thin layer of skin.
Key characteristics of skin tags:
- Benign (non-cancerous) - they don't spread or become cancerous
- Attached by a stalk (peduncle) - they hang from the skin rather than lying flat
- Soft and moveable - they feel fleshy, not firm or hard
- Slow-growing - they typically stay the same size once formed
- Painless - unless irritated or caught on something
Skin tags are extremely common in dogs, especially as they age. Many dogs develop multiple skin tags throughout their lifetime without any health problems.
How to Identify Skin Tags on Dogs
Learning to recognize skin tags helps you monitor your dog's skin health:
Appearance
- Size: Usually 1-5mm, but can grow up to 1-2cm
- Color: Flesh-colored, pink, or slightly darker than surrounding skin
- Shape: Round, oval, or slightly irregular; hangs from a thin stalk
- Texture: Soft, smooth, moveable
- Surface: Usually smooth, may be slightly wrinkled
Common Locations
Skin tags typically appear in areas of friction or folded skin:
- Face and muzzle - especially around lips
- Eyelids - common in older dogs
- Chest and belly
- Armpits (axilla)
- Inner thighs and groin
- Legs and paws
- Ears
- Under the collar area
Skin Tags vs. Other Growths
Not all lumps and bumps are skin tags. Here's how to differentiate:
| Growth Type | Appearance | Concern Level |
|---|---|---|
| Skin Tag | Soft, hanging on stalk, flesh-colored | Low - Benign |
| Wart (Papilloma) | Cauliflower-like, rough surface, often multiple | Low - Usually benign |
| Lipoma | Soft, round, under the skin, moveable | Low - Fatty tumor, benign |
| Sebaceous Cyst | Round, may have pore, can express material | Low-Medium - Can become infected |
| Histiocytoma | Red, button-like, appears suddenly (young dogs) | Low - Usually resolves on own |
| Mast Cell Tumor | Variable, may change size, can be itchy | High - Can be cancerous |
| Melanoma | Dark colored, irregular borders, may ulcerate | High - Often cancerous |
Warning Signs of Cancer:
- * Rapid growth (noticeable change in days/weeks)
- * Hard or firm texture
- * Irregular borders or asymmetry
- * Color changes (especially darkening)
- * Ulceration, bleeding, or oozing
- * Attached to underlying tissue (doesn't move freely)
- * Multiple growths appearing quickly
What Causes Skin Tags in Dogs?
The exact cause of skin tags isn't fully understood, but several factors are associated with their development:
Known Risk Factors
- * Age: More common in middle-aged to senior dogs
- * Friction: Areas where skin rubs together
- * Genetics: Some breeds more predisposed
- * Obesity: More skin folds = more friction
- * Chronic irritation: Collar rubbing, scratching
Predisposed Breeds
- * Cocker Spaniels
- * Poodles
- * Bulldogs (English & French)
- * Boxers
- * Labrador Retrievers
- * Golden Retrievers
- * Breeds with loose skin
Some theories suggest parasites (like mites or fleas) and chronic skin infections may contribute to skin tag formation, though this hasn't been definitively proven.
When to Worry About Skin Tags
Most skin tags are harmless, but certain situations warrant veterinary attention:
See Your Vet If:
- It's a new growth - all new lumps should be checked at least once
- Rapid growth - noticeably bigger within days or weeks
- Color changes - becoming darker, red, or mottled
- Bleeding or discharge - even if caused by trauma
- Ulceration - open sore or wound on the growth
- Changes in texture - becoming hard, firm, or fixed
- Your dog is bothered - licking, scratching, or painful
- Location concerns - affecting vision (eyelid) or eating (mouth)
- Multiple new growths appearing quickly
The Importance of Diagnosis
Even if you're confident a growth is a skin tag, having your vet confirm this during a routine visit is wise. Some cancerous growths can initially look benign. A fine needle aspirate (FNA) or biopsy provides definitive answers.
Removal Options & Costs
Skin tags don't require removal unless they're causing problems. However, removal may be recommended if the tag is:
- Getting caught on things and bleeding
- Irritated or infected
- In a problematic location (eyelid affecting vision)
- Bothering your dog
- Cosmetically concerning to owner
Removal Methods
| Method | Description | Cost |
|---|---|---|
| Surgical Excision | Cut off with scalpel, may need stitches | $200-$500 |
| Ligation | Tie off base to cut blood supply | $75-$150 |
| Cryotherapy | Freeze with liquid nitrogen | $50-$100/tag |
| Electrocautery | Burn off with electric current | $100-$200 |
| Laser Removal | Vaporize with laser (precise) | $150-$400 |
Additional costs may include:
- Examination fee: $50-$100
- Sedation/anesthesia: $50-$200 (if needed)
- Biopsy/histopathology: $100-$250 (if tissue is tested)
- Follow-up visit: $50-$75
Never Remove Skin Tags at Home
Do not attempt to cut, tie off, or remove skin tags yourself. This can cause significant bleeding, infection, pain, and incomplete removal. What looks like a skin tag could be something more serious. Always have a veterinarian perform removal.
Home Care & Prevention
While you can't completely prevent skin tags, you can minimize risk factors and monitor existing ones:
Monitoring Tips
- Regular skin checks: Examine your dog weekly during grooming
- Photograph growths: Document size for comparison over time
- Note the location: Keep track of where growths are
- Watch for changes: Size, color, shape, texture
- Maintain grooming records: Your groomer can help spot new growths
Prevention Strategies
- Maintain healthy weight: Reduces skin folds and friction
- Proper-fitting collar: Avoid chronic rubbing
- Keep skin clean and dry: Especially in skin folds
- Address allergies: Reduce scratching and irritation
- Regular grooming: Helps identify new growths early
If a Skin Tag Gets Injured
- Apply gentle pressure with clean cloth to stop bleeding
- Clean the area with mild antiseptic
- Prevent your dog from licking (cone if needed)
- Monitor for signs of infection
- See your vet if bleeding won't stop or infection develops
Frequently Asked Questions
What do skin tags look like on dogs?▼
Dog skin tags are small, soft, flesh-colored or slightly darker growths that hang from the skin by a thin stalk (peduncle). They're typically 1-5mm in size but can grow larger. They feel soft and moveable, unlike harder lumps. Skin tags are most common on older dogs and often appear on the face, eyelids, chest, legs, and armpits.
Are skin tags on dogs dangerous?▼
Skin tags on dogs are almost always benign (non-cancerous) and harmless. They're simply overgrowths of skin cells. However, any new growth should be checked by a vet to rule out other conditions like warts, moles, or cancerous tumors that can look similar initially.
What causes skin tags on dogs?▼
The exact cause isn't fully understood, but skin tags are associated with friction (areas where skin rubs), aging, genetics, and possibly parasites or chronic irritation. Overweight dogs and certain breeds like Cocker Spaniels and Poodles may be more prone to skin tags.
Should I remove my dog's skin tag?▼
Skin tags don't need to be removed unless they're causing problems - getting caught on things, bleeding, becoming irritated, or bothering your dog. Never try to remove a skin tag at home as this can cause infection, bleeding, and pain. Always have a vet remove skin tags if needed.
How much does it cost to remove skin tags on dogs?▼
Skin tag removal typically costs $75-$500 depending on the method, location, and whether sedation is needed. Simple removal during a routine visit may cost $75-$150. Surgical removal with anesthesia costs $200-$500. Cryotherapy (freezing) costs $50-$100 per tag. Multiple tags may be discounted.
How can I tell a skin tag from cancer on my dog?▼
Skin tags are soft, moveable, and grow slowly on a stalk. Warning signs of cancer include: rapid growth, hard or firm texture, irregular borders, color changes, ulceration or bleeding, attachment to underlying tissue, and changes in your dog's behavior. Any suspicious growth should be examined by a vet - a biopsy may be needed for diagnosis.
The Bottom Line
Skin tags are extremely common, benign growths that most dogs develop as they age. They're typically harmless and don't require treatment unless they're causing problems. However, because other growths can look similar, it's important to have your vet examine any new lump or bump.
Regular grooming and skin checks help you catch new growths early. Document any changes with photos and measurements, and don't hesitate to contact your vet if something looks concerning.
When in doubt, get it checked out - early detection of any problematic growth leads to better outcomes.
