Hi Ed,

Based on the image, it appears that the sore on your dog’s leg has a rough, dry, and crusted surface with some pigmentation changes. Given that it's a painless lesion that has been present for several years and has slowly grown, this could likely be a condition called a cutaneous hyperkeratosis or possibly a benign seborrheic keratosis. These are generally harmless but can grow over time and may become more noticeable. However, because it’s expanding, you should consider a few additional possibilities, including benign skin tumors or, less commonly, malignant growths.

Most Likely Condition: Cutaneous hyperkeratosis or seborrheic keratosis

Recommended Action: Apply a pet-safe moisturizing ointment, such as one containing aloe vera or vitamin E, to help soften the dry, crusty area. This can prevent cracking and further thickening. Avoid picking at or trying to remove the crust as this can lead to irritation or infection.

Alternative Possibilities: Benign Skin Tumor (such as a histiocytoma or papilloma): These are generally harmless but can sometimes become irritated or infected.

Recommended Action: If the growth continues to expand or becomes irritated, a visit to the vet for a biopsy might be helpful to rule out any malignancy.

Rare Possibility of Malignant Skin Growth: Although unlikely, any skin growth that changes over time should be monitored.

Recommended Action: Schedule an appointment with your vet for a full examination. They may recommend a biopsy if they find any concerning signs.
In terms of medication, over-the-counter creams for moisturizing can be helpful, but avoid any human ointments that contain steroids or other active ingredients unless advised by your vet. If there's any bleeding or signs of infection, your vet might prescribe a topical antibiotic.

All the best to you and your dog!
