What are Skin Tags?
Skin tags are a type of growth comprised of fibrous tissue that can appear as a single or multiple lump or bump. This connective tissue is made up of collagen proteins, and is essential in the formation of such specialized tissues as bone and cartilage, as well as provides the connective support for the various organs and systems in the body. While some skin tags are considered to be benign cancers, termed fibromas, most are deemed non-cancerous, and can be referred to by several names. These include acrochordons, fibrovascular papillomas, collagenous hamartoma, hyperplastic or hypertrophic scar, and fibroepithelial polyp.
Just like their human owners, dogs can develop small skin lumps on the surface or just under their skin. These skin tags often appear as a dog ages, and though they can be unsightly, they are quite harmless. Very often, these growths are connected to the body by a stalk-like tissue.
Symptoms of Skin Tags in Dogs
Skin tags grow slowly and can take a long time to be noticeable. They are located on the skin, or just under the skin, and can vary in size and appearance. While harmless, they can cause distress if they grow too large or in a location that compromises your dog’s normal daily activity, or if they become damaged, in which case they can bleed and possibly become infected. Signs your dog may have a skin tag include:
- Stalk-like growths
- Growths with a wart-like surface
- Single or multiple growths
- Growths that include hair follicles
- Flattened plaque-like growths
- Growths that can bleed if damaged
- Secondary infections of growths
Types
Skin tags are often referred to as hamartomas, which are described as a nodule of redundant tissue. Two types of these are:
Fibroadnexal Hamartomas – Also called collagenous hamartomas, these are the common skin tags seen in many dogs. Often, these are hairless growths, and form near the lower limb regions and pressure points.
Follicular Hamartomas – This is a type of fibroadnexal hamartoma, and more rare in dogs. These growths are often found in multiples, and can be characterized by flattened masses with thick hairs.
Causes of Skin Tags in Dogs
Skin tags are composed of fibrous tissues made up of collagen proteins. This fibrous tissue is a normal component of the body, and creates the supportive connections and tissues that hold the organs and body systems into place. The cells responsible for the production of the fibers that makes this connective tissue are called fibroblasts, and if these cells are overactive, this can cause an abundance of fibrous tissue, resulting in a slow-growing mass near or on the skin.
Though skin tags can appear on any breed of dog, there seems to be an increased risk in larger breeds. Skin tags more commonly appear in dogs that are middle-aged and older.
Diagnosis of Skin Tags in Dogs
If you see a growth on your dog, it will be vitally important to determine if such a growth is a harmless skin tag, or if it is a tumor or other growth that is signaling a more serious problem, such as cancer. While it is common to see growths appear on aging dogs, monitoring certain factors can be helpful to you and your veterinarian when making a determination about your dog’s condition. Once you see a bump or lump on or under the skin, take notes on the appearance, size and location of the bump. Taking pictures with an object of a fixed size next to it, such as a coin or ruler, can help to determine growth when compared to a later picture. Never use scissors or a razor to remove any hair near the growth, but instead, use electric clippers or a beard trimmer to prevent damage to the growth.
If you notice certain characteristics about the growth, you should not delay in seeking a medical opinion. These can include a rapidly growing lump, a dark colored growth, or a bump near your dog’s ear, nose, mouth, or mammary glands. Other symptoms concurrent with the growth can also cause alarm, such as changes in appetite, weight and energy levels, signs of discomfort and pain, or vomiting and diarrhea.
Be sure to tell your veterinarian details of all symptoms you’ve noticed, including any changes you’ve seen in the growth. Your vet will examine your dog and evaluate the lump. A fine needle aspirate may be performed to collect a sample to analyze. Usually, a biopsy is recommended to determine if the growth is benign or malignant, the examination of which can confirm a diagnosis of a skin tag.
Treatment of Skin Tags in Dogs
While some skin tags can shrink in size over time, most of them will remain unless they are surgically removed. Surgery to remove these growths is optional, as often skin tags cause no harm to your dog. However, removal can be recommended in certain cases, such as to confirm a diagnosis with a biopsy, or if the size or location of the growth is causing physical problems, pain, or secondary infections.
Another method of removal is through cryosurgery. Nitrous oxide or liquid nitrogen is used to destroy the unwanted tissue by freezing it. The tissue then falls off or dissolves within four weeks. This procedure can be attractive for those dogs who are at an increased risk of complications due to anesthesia, as only a mild local anesthetic may be needed. The process is only temporarily painful during the freezing with no pain during recovery. Sometimes, the first treatment is not sufficient and may be repeated within two to three weeks.
Recovery of Skin Tags in Dogs
While occasionally, skin tags can shrink on their own, more often they will be a harmless addition to your dog’s skin until removed. After any type of removal, prevent your dog from licking, chewing, or scratching at the area to prevent any further damage. An Elizabethan collar can be used. Keep the area clean and monitor it for changes. Be aware that once your dog has developed a skin tag, he may be more prone to develop others.
Skin Tags Questions and Advice from Veterinary Professionals

We have a 13 year old Cock-a-poo who is good health but a couple of years ago from one grooming to another he came out with over 30 skin tags. While he's been on an elder dog prescription food, we thought he might have an allergy so we switched him over to Northern for senior dogs, but it actually seems to have gotten worse?!?!? While we have taken him to the vet and were told that they are not cancerous, but that there was nothing we could do about it?!?!? Now I'm wondering if his flea and tick pill might be the problem?!?

My 7 year old Cockapoo has had a skin tag on his paw for over a year and the size has not changed. It was never a concern until last week when we saw the very same skin tag very swollen tripled in six. The skin tag was about bread crumb size and now the size of a skittle or bigger. The biggest problem and that he keeps messing with it. He likes to lick it not stop and I can see that it is getting irritated.

Pearl has calluses on both elbows. She also has skin tags on top of the calluses which she scratches with her nails and they bleed.
This week one skin tag bled so much we though she may die from loss of blood. We could not get it to stop which was extremely scary for us not to mention disgusting! It looked like we had dissected her in our living room. Our vet said there was nothing to be done.
She is 11 years old so he may not want to do surgery but it has bleed 3 more times and out lives are literally turned upside down! We keep it wrapped at all times and apply liquid bandage but we are fearful one could erupt when we are away and we would then come home to a dead dog and a house that looks like a murder scene.
Can they be frozen off?
She has always had a dog bed or our couch or bed.
My Weimaraner has the same problem, snleeding skin tag on her leg and yes my house has looked like a murder scene. Thank goodness for peroxide for the clean up

My yorkie has a skin tag near anus. It seems not to bother Cosmo. My vet wants to operate & am leery because of his age. Also, Cosmo has respiratory issue. Should I get a second opinion?
I read that freezing the tag may be a lot safer then operations! Now they have kits to do it yourself! Cool right! Pardon the pun!
Hi I have a yorkie his name is bebo he 8 going be 9 he has skin tag but he continued growing more all over I don’t know what to do in this case. I took him two time to pet smark but now he is in a point where he limped also any idea how
My dog, Sammie, has skin tags in several places. Our vet hasn't recommended removal, however, they are not near her anus. She does chew on one near her paw, but it has never caused bleeding or anything else. I would personally get a second opinion because the surgery seems to be more risky than the issue itself.

Casey has a skin tag on the corner of her eye on her eyelid. She keeps scratching it or opening it. It keeps bleeding in her eye and she cant stop blinking. I dont know where to get it removed and how much it would cost to get it off. Its really bugging her and she now has to sleep with her eye partially open. We try to wipe it and clean it as best we can but i dont know what else to do.
It seems most likely that the tag is irritating her from the inside out! If it’s wont stop bleeding when after she scratches it, then buy some WoundSeal Topical power for minor external bleeding! Later, I would think about freezing it! The freezing should help out with the irritation and I think have her sleep better. But, these are my experiences from my own life and are by no means medical professionall help. Ok?

I was recently cleaning out my dogs ears when I noticed he has four little 1 centimeter growths which are pretty concealed by his fur but idk if it is cancerous and am kind of worried. He has also had a little bump on the side of his nose that went away while another one appeared. They done give him any discomfort or pain as far as I know but I would still like to know what to do about it

We just noticed a skin tag on our lab mix. The end of it is black, but the rest of it is pink. It is about an inch long, and didn't seem to bother her when we examined it. The black at the end seems to be protruding from it, but not oozing or coming off of anything. Should we be worried? I have a pic, but don't know how to send it here.

Hello. My beagle has several skin tags on her body and they’ve already been identified as harmless by her vet. There is a large one on her front paw that looks like a mini brain. Lots of small tags on top of each other. Last night a few of those turned dark red and now blackish. It looks like blood is pooling inside. What can I do at home (prick them?)? Should I take her to the vet? How urgently?

My dog has a large skin tag on jhis neck. Over time it started to dry out and now it has cracked and there is some bleeding which I cleaned. Is this normal for a skin tag? Do they dry out and end up cracking or falling off?

My 3 yr old female schnauzer has been acting like something bit her on the backside and she will jump up or suddenly sit down. The groomer noticed something long and black hanging from her vulva. It looks like a black maggot, but is obviously part of her skin. The vet says it's a skin tag, but it doesn't look like any tag I've ever seen. What else might it be?

I just found what appears to be a skin tag on my 6 yr old American Pit Bull Terrier. It is black (like tar) in color and not round shape on her lower side near pelvic region. With it not being the same color as her skin, should this be investigated by the local vet?
