What is this new hard spot on my dog's skin? Should I worry?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | neutered | 8 years and 11 months old | 80 lbs

Hi, my lab has a lot of lipomas which we have had tested and are not cancerous. He does have this new spot (which I know is not a lipoma) that started as more of a pink/red spot and then changed to pretty much the same color as his skin so I thought it was healing, but is now hard, its only maybe the size of a pencil eraser. Should I be worried?

Ouch! Any new change should always be checked out by your vet, especially if it's different from any other growths seen on the body. Skin tags and other growths can sometimes cause pockets of hair loss like this, however, other issues such as bacterial or fungal infections (like ringworm) can also cause round patches of hair loss like this as well, which need to be treated by a vet. A quick fine-needle aspirate can determine if there are any concerns, and if your vet suspects something bacterial or fungal, it can be treated with oral antibiotics and cleaning of the area. Until you get to your vet, keeping an eye on the spot for any changes in size/shape, and keeping Eddie from licking it can help monitor for changes and reduce the chances of a secondary issue. It's also important to keep the area clean and dry, and thoroughly wash your hands after handling the area as some bacterial/fungal causes can be contagious to people.
