Hello there! This is most likely a benign lump called a histiocytoma, which is a common condition that shows up on the face and paws in young dogs. This can only be confirmed by a veterinarian, by considering the size, shape, location, and the age of your dog, it's the most likely cause. I recommend a visit to your vet so that they may offer a definitive diagnosis. They will give Nikki a full exam, and most likely they will obtain a small sample of the cells inside the mass with a small needle. This is called a fine needle aspirate, or FNA. These cells will be examined under a microscope so that the vet can rule out other, more dangerous tumors. Histiocytomas most often spontaneously resolve on their own, but it can take weeks or months to go away completely. Some owners prefer to have them surgically removed, which is usually curative. If Nikki starts scratching at the lump, or if it becomes irritated or starts oozing, a visit to the vet is definitely in order as it could cause an infection. Good luck, and I hope Nikki recovers well!
