Worried About Skin Tags and Moles On Your Pet’s Skin?

Most people know that skin tags and moles are common on human skin, but did you know that they can also grow on pet skin? While it's not uncommon for healthy animals to have a few of these benign growths, you may be wondering why they appear. In this post, we'll briefly look at what skin tags and moles are and the most common reasons they appear in your pets. 

What are Skin Tags and Moles

Pet skin tags and moles are growths that can occur on the skin of animals. They are usually benign, meaning they are not cancerous. Skin tags are small, fleshy growths that protrude from the skin. 


Moles are darker than the surrounding skin and may be raised or flat. They can also occur anywhere on the body but are most common on the face, chest, and back. Pet skin tags and moles are generally harmless, but if you notice changes in size, shape, or colour, you should have your pet examined by a veterinarian.


Why Do Skin Tags And Moles Grow in Pets?

The exact cause of skin tags and moles isn't clear, but several factors seem to contribute to their development. These include:


  • Excessive sun exposure: Pets with short fur or who spend a lot of time outdoors may develop lesions on their skin due to sun exposure. Skin tags are one such growth that may appear on your pet's body after too much sun exposure. If you notice that a particular spot on your pet's skin is constantly exposed to the sun, be proactive by applying sunscreen or keeping them indoors during peak hours.
  • Weight gain: Extra pounds add not only to your pet's waistline but also to its skin. This excess skin can lead to growths of fat cells and the development of skin tags and moles. Pet owners should make sure their pets maintain a healthy weight. 
  • Side effects from medication: Some medications can cause an increase in the development of skin tags. Skin tags are a side effect of long-term prednisone treatment in humans, cats, and dogs.
  • Friction: Skin tags and moles on dogs or cats are most commonly found in areas where clothes rub against the skin, such as under the arms or under a collar.
  • Genetics: A genetic predisposition can contribute to the growth of skin tags. These benign growths seem to run in families, and some breeds are more prone to them than others. Boxers and Cocker Spaniels seem to be especially prone to this condition.


Most skin tags and moles are nothing to worry about. But if you notice a change in size, colour or shape that persists for several weeks, it's best to have your pet examined by a veterinarian.
