Chloe is adorable! The lump on her face could be due to a number of issues, including a benign or malignant mass, cyst, granuloma, among others. Given her young age, a benign mass like a histiocytoma seems most likely, but the only way to definitively determine the cause of this lesion is through a fine needle aspirate. This procedure is performed by drawing a few cells from the lesion with a needle so that the sample can be examined microscopically. From there, the vet will be able to provide more information as to whether it is better to monitor the lesion (histiocytomas typically go away without intervention within 3 months) or surgically remove it. I do recommend taking Chloe to her vet to get to the bottom of this issue. I hope this helps and that all goes well!
