Skin Tags on Dogs

Written by Wyatt Robinson

You are lounging on the couch watching TV one evening with your companion curled up at your side. You are absentmindedly stroking his back and chest, when suddenly, your fingers brush up against something soft and fleshy. It bends and folds, and the next thing you know, you are bent over, digging through fur, trying to figure out just what this thing is. It can be disturbing to find such a growth jutting from his chest, but the truth is, skin tags on dogs are quite common.

They are usually nothing to worry about, but they can become a problem. This article will help you to identify them, lessen the chance of them occurring, and walk you through several options for getting rid of them for good.

In a nutshell, skin tags are benign growths that grow out from the body. Usually only a few millimeters long, they lie flat, be round like a mole, or even protrude from the body like a grain of half-cooked rice. They are also known as fibropapillomas and achrochordons, and in truth, they are actually quite common.

Dogs of all ages can develop these ugly little tabs of flesh on their face, chest, armpits, and legs, though the older a dog gets the more likely one is to form. They are often mistaken for tumors or canine skin cancer, but most owners need to not worry. Sure, finding one in the fur of one of your closest family members can be disturbing, but the truth is, unless it is causing your pet pain or discomfort, they are usually not harmful.

Perhaps it would be best to think of them as soft, misshapen warts than a spreading infection. In fact, by the time you found it, it probably has already grown as far as it ever will. But like any change in health status, it shouldn’t be simply ignored.

Dog’s Skin Tags

You can usually tell the difference between a life-threatening disease and a merely irritating growth by carefully examining the area. Skin cancer will appear as a lesion that has a watery discharge; it will also be painful for your pet at the slightest touch. The lesion may also change in size, texture, and color.

Skin tags, on the other hand, tend to have an extremely flexible base which allows for the upper part of the growth to be moved around with your finger and won’t cause pain unless it is inflamed or infected. A good rule of thumb, however, is “When in doubt, ask your veterinarian.” If your vet cannot tell the difference from a spot check, he or she will perform a biopsy to rule out any malignancy.

Causes of tags

So, you may be asking yourself, “Why do dogs get skin tags?” Well, there aren’t any definitive answers to that question. Many veterinarians and other animal specialists have theorized many different reasons as to why they form. Although the professionals have not been able to solve the puzzle, they do believe that there is a common link to the development of tags and the following factors.


There is a long list of parasites that attach themselves to your dog. Fleas, ticks, lice, and mites are the most common, and most owners soon know when their pets have become infested. The unwanted residents will cause itching, and if not taken care of quickly, your dog can damage his skin while attempting to scratch them away.

The damaged skin can become inflamed develop a host of infections and diseases. Once treated, tags can develop after the flesh heals.


There is so many things in your dog’s environment that can lead to the formation of tags on the skin. Exposure to pesticides, chemicals, acidic soil, and just about anything else that he can come into contact with while romping through the house or exploring the back yard can have an adverse effect on his skin.

A poor fitting or tarnished collar could cause inflammation as well. Just think of all the things that could dry out and irritate your own skin. Those same irritants can get down beneath the coat and do some horrendous damage before it cared for. But even after the initial damage heals, the new flesh especially susceptible to forming an abnormal growth.

Improper skin care

Much depends on the breed, but for the most part, dogs need to be bathed on a regular basis. The dirt and whatever else they’ve tracked into the house has to come out at some point, but there are owners who will bathe their dogs the moment they think their pets are starting to “get a smell.”

The problem with this is that too much washing can inhibit the skin from producing natural oils necessary to keep the skin and coat healthy. Here are some tips on proper dog bathing that you might be interested in, check it out.

Harsh soaps and shampoos can contribute to the development of tags by stripping away the oils and causing the skin to dry out and chafe. One great way to avoid skin problems is to use a on organic shampoo created specially for dogs, like the Oxgord Organic Oatmeal Shampoo and Conditioner with Aloe Vera — click here to see the price and place an order.

Poor diet

Along with a whole host of medical issues, a dog that is not properly fed can easily develop skin malformations. If he isn’t getting the right nutrition, or if he is eating something that he shouldn’t be eating, his weakened immune system could cause rashes, cracks in the skin, and other outbreaks that could eventually lead to tag growth. Our article on natural food for your pooch is a good read that can give you more insight.

Poor diet

Proper food and routine visits to the vet can go a long way in eliminating diet as a factor. If you haven’t thought about this aspect before, grain-free dog food is the most recommended for a healthy, happy dog. You can even order the best online, from here.


Like so many medical conditions, skin tags can be an inherited problem. So, if this is something that is in your dog’s breeding line, it is already too late. There is nothing you can do to stop them from occurring, but you may be able to lessen the chances of them by taking preventative measures outlined in this section.

In the meantime, monitor your pet if the tags become infected or otherwise bothersome, take him to a veterinarian. Most veterinarians have had plenty of practice slicing them off.

Monitoring tags

There is a good chance that if you find one tag on your dog, then you’ll probably find some more. You should give him a thorough grooming every day. While you brush him, check out all the typical areas where these nasty things can form, and then run your fingers through the coat. Make sure to explore armpits and creases in the flesh, such as behind ears, beneath the jawline, and around the base of the tail.

If you find a bump but you can’t really get a good look at it, you should remove the hair around using grooming scissors which allow you to work without harming Fido. If you don’t have a pair at home, you can find a great product here.

If you search deep enough, and often enough, you should be able to find any suspicious bumps that may require further examination. If you believe that the tag could be a problem. Don’t hesitate to ask your vet. He or she should be able to tell you if something should be done about them.

Vet looking for skin tags

If your vet informs you that the tag is not a threat, you should still continue to monitor it for changes. It is rare, but some of them, especially ones that form around the lips and nose, can become cancerous. So watch for any changes in color or size. Also, you should pay attention to how your dog treats the growth. If he continually scratches or bites at it, it may be causing him discomfort.

Tags that have been cut or abraded can become inflamed or even infected if not treated immediately. As stated earlier, these formations aren’t typically a threat to your pet’s health, but sometimes the best way to deal with them is to get rid of them.

Large tags can pose a problem either because of their size, their location, or a combination of both. Dogs may scratch or gnaw at them, or they could get caught on a chain link fence or other object that your pet likes to crawl through or beneath.

Torn tags can bleed profusely, and are prone to infection. Tags that form on the tail are highly vulnerable to damage. Take the time to examine these on a daily basis, and if they appear to be affecting your dog, you should consider having them removed.

Removal of tags

Believe it or not, there are a few options when it comes to dog skin tag removal. The most obvious choice is to make an appointment with a veterinarian and have the annoying thing excised. One problem with this choice is that it the procedure could cost you several hundred dollars, so you may not be able to afford it.

The age of your dog may also play a factor. Your vet may tell you that he may be too old to justify the expense. Don’t be discouraged if you think money or age will in the way of your favorite fur ball living tag-free. There is another option.


For the most part, removing one of these bothersome nodes is an outpatient affair. You will go into the room with your dog, and while he lies on the table, the vet applies a local anesthetic to numb the area around the tag. If he becomes aggressive or overly skittish, you may have to hold him down throughout the procedure.

Once the anesthetic has set in, the vet will slice the tag away. One good thing about this approach is that your dog will not feel any pain, and as soon as the vet steeps away from the table, the two of you can be on your way home.

Vet removes skin tag

In this type of procedure, there is little cutting, so most vets will not sew the area shut. You will need to monitor the wound over the next week to ensure that the patient is healing as he should. Also, make sure that he doesn’t scratch the area as it heals, because that will slow healing, and even perhaps induce another tag. There will be a scar, of course, but it will fade in time.

Home remedies

A problematic tag of skin will continue to cause your dog discomfort regardless of its age or the amount of money that you might have for the time being. Or, perhaps you have just gotten sick of looking at the ugly thing dangling from your buddy’s chest and you want to take matters into your own hands.

You can’t just reach over and snip off the offending mass with a pair of toenail clippers, but it is possible for you to get rid of it without ever leaving your home.

The methods detailed below are two of many suggestions available on how to remove them, but before you decide on your approach, you should give it plenty of thought. Do the steps sound logical to you? Does it sound like it won’t harm your dog? Are you willing to see the steps through all the way to the end? If you answered “yes” to these questions, then you can give it a try unless the tag appears around the mouth or the eyes. These should only be removed by your vet.

Cutting and cauterizing

This technique is similar to how a veterinarian would approach the removal of a tag. It requires a trusting dog, a partner that can keep a firm grip on him, and for you to keep a steady hand throughout. The advantages to this method is that it is over in a matter of minutes; but you shouldn’t try it if the sight of blood, or the idea of cutting your pet disturbs you.

Before you start, make sure that you have following:

  • a pair of curved (mayo) scissors
  • a disposable razor
  • isopropyl (rubbing) alcohol
  • 10% iodine solution
  • bottle of water (12 oz)
  • cotton balls
  • plastic bowl wide enough for scissors to lay in
  • electro-cauterizing pen or soldering iron
  • bandages

After your partner has calmed your dog, trim and shave the hair around the tag and then swab the area with a cotton ball soaked in alcohol. Next, sterilize the scissors by letting them sit for at least a minute in a bowl of water and a teaspoon of iodine. Then, with the dog held firm, cut the tag at its base and then press a bandage to the wound to staunch the bleeding.

Finally, cauterize the place that you cut with the pen or soldering iron by touching the hot end to the wound for two seconds. Cover it with a bandage and monitor it throughout the week. If you have done this properly, the tag will not grow back.

Tying off tags

This procedure is most effective for tags that protrude enough that you can pinch it between your fingers. It may seem a little strange at first, but it is rather simple to do and does not involve cutting your beloved family member. Before you start, make sure that you have someone with you who has a good relationship with your dog and the strength to hold him down.

You will also need to gather the following:

  • a foot of fishing line, or dental floss
  • a pair of scissors
  • a disposable razor
  • isopropyl (rubbing) alcohol
  • cotton balls
  • a cone collar (like the one vets use after spaying/neutering)

Once you have gathered your materials, have your partner hold your dog down while you trim and shave the hair around the tag. You don’t need a bald patch; however, make sure there is no hair around the base of the formation.

Then, dab the area generously with isopropyl alcohol. You and your partner should be talking and stroking him to ensure that he remains calm and that his movement is kept to a minimum. By this time, he has sensed that something unusual is about to happen, and he probably won’t like it.

As long as he is calm, tie the fishing line as tight as you can around the base of the tag. Wrap it around several times, and tie it once again. This will hurt for a minute or two, but he will soon forget that it is there.

Place the collar around his neck (or a dog shirt if it’s in the chest area) to keep him from biting at the tag as it swells up. It will likely turn a shade of purple that causes you to regret your decision, but in three days, it will begin to shrivel. A few days later, it will fall off, leaving hardly a mark.


Skin tags can be unsettling for any dog owner. They are unpleasant to look at, and some people may even view you as a poor master because one or more has formed on your companion. Take heart that they are quite common, and they usually aren’t a serious threat to your pet’s overall health, though they can be symptoms caused by a different issue.

Look for skin tags

Tags should be monitored for damage or inflammation, and if found, it should be brought to your vet’s attention immediately. And remember, you have more than one option to have the tag removed, if necessary. So, now that you know what skin tags are and what you can do about them, you can be prepared the next time you find one.

    My brother’s Collie seemingly developed what looked like a mole or a large skin tag on the left side of his lips.
    There’s also a smaller one inside his cheek flap on the opposite side of his mouth. Do we have to get this checked out? We’re thinking of the cost, it might be expensive. :(

    • Early assessment will help save you from all the trouble. It is better to have those checked by the veterinarian for further intervention that might be required. It can cost you some money, but it will save you from all the stress and worries.

    When we find skin tags on ourselves, we usually wet a bandaid with vinegar and leave it on for half a day for a couple of days until it shrivels. Vinegar is pretty effective for humans, I’m thinking may be it will help as well with dogs, won’t it? While I haven’t encountered a skin tag problem with our pooches, I believe it’s time to give them more attention.

    • It will not yield the same effect for dogs. Vinegar is often used as a home remedy for warts but it is not effective at all for skin tags. The acidic nature of the solution might also irritate the dog’s skin so I really don’t recommend it.

  • Patricia Parket

    Our dog suddenly developed a skin tag near the right muzzle of his lip. We thought it was a tick so we removed it. However, we soon realized that it’s a skin tag. After a few days, it appeared again on the same spot. What could be causing this? What do we do?

    • Some skin tags can be persistent and may require special procedures being done in the clinic. What you did is just cutting the part that has grown, but not completely addressing the base of the skin tag. The procedure is usually short, and your veterinarian will take specimens for further testing.

      My Yorkiepoo occasionally gets small skin tags on her back which become flexible and either fall off by themselves or I can «worry» them until they come off, unfelt by the dog. A more bothersome problem is that she develops warts on her back and sides and even around the toes of her feet. She has one on her side right now that hasn’t responded to freezing, so we’ll go to the vet who can cauterize them.

  • Harvey Bellamy

    I rescued a dog tied to a tree and noticed that he had a fatty, large piece of skin hanging from is stomach. It did not change but on 8/5 he had a rabies shot. The next day that tag had tripled in size, felt warm, and was a red tint. I took him to the vet because of infection and they want to charge $767 USD to remove it. Are there any alternatives to get rid of it without breaking the bank??

  • Hi, Harvey,

    It can be something systemic. If it still increased in size now or significantly changed in appearance or color, it would be better to seek for a second opinion, or set terms if the preliminary bill is way too high.

  • Let us know what happened to your dog’s preliminary visit to the vet who will cauterize the skin tag. Some skin tags and warts can be very stubborn and cannot be removed easily.

  • derel schrock

    Well, the skin tags are small and on her back & sides, and only occasionally. Yesterday, I worried a small one off her shoulder. The wart is more stubborn, but I haven’t booked an appt to have it cauterized. I spray it with something that was supposed to eventually make it go away. It’s called GentaSpray, and the generic may be Gentamicin Sulfate.

    • Thanks for keeping in touch, Derel. Gentamycin is one of the most common management for warts. However, there are some warts that don’t respond to Gentamycin. You can observe if considerable change can be seen after several days of treatment.

    I put a robberband to tie the tag to cut the circulation to it. It got nasty purple and a bit bigger. Also was bleeding but not excessive. I got kinda scared and took the robberband off cause he seemed very uncomfortable and kept licking it. Did I do the right thing to take it off? Will what was in that tag go up into his body? Someone please help me understand so I can make my next move. Thank you

  • Make sure to put an ointment to the wound to inhibit the development of infection. What you did is the usual home remedy which often works. For now, just keep the wound clean and observe for signs of worsening.

    Hi i discovered a piece of approximately 3cms wide and 2 cms long behind my GSD 8 months old pup. Please help!?

    • Wyatt Robinson

      If the neck (the connecting portion between the body of the skin tag and the body) is narrow enough, you can do the rubber band technique for this.

  • Rachel

    It’s a little concerning that you would suggest to us removing anything from an animal without pain medication… that seems cruel. As untrained people we have no idea if what we are removing is going to be super painful or not.

    • Wyatt Robinson

      Ideally, skin tags should be removed by the veterinarian. However, smaller skin tags can be safely removed without anesthetics because they lack the nerves you usually find in cysts or other bumps.

  • Oscar Patton

    Can a person use the tool farmers use to castrate cows and pigs on large skin tags on dogs. My dog has one the size of a small plumb. Thanks

    • Wyatt Robinson

      Hi Oscar,
      Castrating tools can be used to remove skin tags. Just implement the similar precaution, including proper sterilization of the tools before and after use.

  • Anonymous

    Do the dogs feel this at all.. I mean my dog has one as wide as a green grape and almost 2″ length. Ut hangs between her to front tweets and looks like a pair of old mans.. Well it quite unsightly. And worse over it doesn’t seem to be stoppingits growth since it showed up and went from pimple one night to the morning being a quarter of inch legbth aroubf 13-16 months ago. I want to remove it am not financially capable right now to bet her for this and worry a lit it is too large to not hurt her terribly.

    • Sallie

      It may be a clogged pore if it grew that quickly, is it dry looking at the very end? If you squeeze it at the very end see if you can scrape off the plug.

      • Wyatt Robinson

        Thanks for pointing that out, Sallie. Some skin tags are often confused with clogged pore or an infection. Clogged pores can be extracted and applied with topical ointments and will eventually heal on its own.

    • Wyatt Robinson

      Like skin tags found in humans, skin tags on dogs, in general, can be removed without application of anesthetics. Its growth can be deterred with topical medication which can prepare it for a quick removal. If you intend to DIY the skin tag removal, make sure your equipment are clean and sterilized. If the skin tag further progresses in size, it would be best to have a quick assessment from the veterinarian.

  • Douglas Stokes

    My fur baby has a large cluster of skin tags on the rear leg and a large tag right above it….with her being 11 years old could there be an issue?

  • Ally & Boo

    My pibble had had a tiny little tag on the inside of her hind leg for about a week. I don’t think she even notices it, apparently I’m just the overprotective»pawrent» type. No change in size or color but reading this article has definitely put my mind at ease until we see the vet. Thank you!!

  • Nicole Casalino

    Do not remove skin tags at home!! That is a terrible suggestion!!

    I’ve removed my own skin tag, and it’s very painful and bleeds quite a bit. Do not take the advice suggested in this article to do this yourself. If it’s painful for a human then it’s painful for a dog. A human can monitor and keep the wound clean. A dog cannot. Ignore this article regarding the home remedy, go to a vet and have them provide proper pain medication and have it remove. The vet will also help prevent infections.
