What do we mean when we talk about skin tags on dogs? We’re certainly not talking about (nor would we ever advocate) putting a tattoo on your dog, or any other kind of physical graffiti. No, skin tags are growths that appear on the surface of a dog’s skin. Just like humans, as dogs age their skin exhibits the ravages of time, resulting in skin tags and other such growths.
The typical skin tag starts out as a small, fleshy growth, resembling a wart, any place on a dog’s body, but commonly around the face, legs, and belly. Unlike a wart, skin tags on dogs tend not to calcify, but rather remain soft and retain the color of the dog’s skin.
While skin tags and surface growths like lipomas typically consist of excess skin or fatty deposits and are normally self-contained, localized, and harmless, that does not mean they should be ignored or dismissed. Indeed, any suspicious or random growth has a chance of being cancerous.
Skin tags on dogs are common with advancing age
As dogs reach middle and senior age, their owners should be paying closer attention, especially during normal grooming and bathing, to the external signs of aging. As long as skin tags are not located in their underarms or around the eyes, where they can irritate or impede a dog’s normal functioning, removal tends to be unnecessary and pursued mainly for aesthetic reasons. The most important thing you can do as a dog owner is to be observant.
If you notice any changes, irritations, or abscesses at or around the site of a skin tag, your dog should see a veterinarian to rule out malignant possibilities. Where skin tags grow out of the surface of the skin and have generally no ill effects, there are a number of other growths that affect dogs as they age.
Lipomas and mast cell tumors, for instance, may resemble skin tags on dogs, but vary in their nature and potential long-term consequences. A quick fine-needle aspiration performed by your veterinarian can tell whether cancerous cells are present, which a biopsy will confirm if true.
Lipomas and other fatty tumors on dogs
Lipomas are fatty deposits that form just beneath the skin and fur, rather than appearing to grow out of them. Like skin tags on dogs, lipomas tend to stay soft to the touch, and like skin tags, are usually harmless and painless to dogs. That can vary, though, depending on where they form and whether the dog can scratch or bite at them. Lipomas form as the body and its standard filtration systems deteriorate, purging excess toxins through the skin.
The causes of lipomas are varied, but generally contain elements of food preservatives, medications, and other chemicals, such as traces of chlorine found in tap water. As a dog ages, the body’s ability to filter or excrete these unnatural elements in urine, feces, panting, or sweating can decline. This decline is expedited if a dog is obese or has pre-existing issues with the kidneys or pancreas.
Foreign chemicals and other such substances are isolated, displaced, and stored by the aging canine body in the form of lipomas. Like skin tags, it is usually unnecessary to have lipomas on dogs removed or treated. Lipomas provide a reliable and otherwise-unavailable service in older dogs, and removing one can lead to others appearing. If a sudden growth appears on or beneath the surface of a dog’s skin, the best thing to do is have it tested by a veterinarian. A confirmation of its nature as a fatty tumor will rule out potential diagnosis of cancer.
Mast cell tumors on dogs
Mast cells are part of the immune system, assisting in defense against allergies and in healing processes. Mast cell tumors in dogs are one reason why any strange or suddenly appearing skin growth should be tested. Mast cell tumors may be mistaken for skin tags and lipomas in dogs. Like skin tags and lipomas, mast cell tumors tend to affect mostly older dogs.
Two major differences between lipomas and mast cell tumors are that mast cell tumors can form at any time in a dog’s life and can change size rapidly. Similar to skin tags and lipomas, mast cell tumors can appear anywhere on a dog’s body, but many are found on the lower body, including the genitals, and on the legs.
Another significant difference is that mast cell tumors can be aggressive and spread through the body. Treatments vary depending on the nature of the mast cell tumor and how far it has advanced. Yet another reason to consult a veterinarian at the first sign of a strange growth.
Stay vigilant as your dog ages!
In my research, I’ve come across a number of home remedies and do-it-yourself solutions for removing skin tags on dogs. I’m a researcher, not a veterinary health specialist, and wouldn’t advise or instruct readers to do anything I wouldn’t be comfortable doing myself. Since skin tags can be confused with lipomas and mast cell tumors, the first thing you should do is make an appointment with your veterinarian for a proper diagnosis.
Have you ever dealt with a skin tag or other kinds of lumps on dogs? Have you ever taken it upon yourself to remove skin tags in the comfort of your own home? Have you ever had one removed, only later to find additional skin tags that proved to be cancerous, or to receive a diagnosis different from the varieties discussed above?
