Skin tags should not be removed at home. What appears to be a skin tag could actually be a cancerous lesion. In addition, there is a high likelihood that complications can occur such as excessive bleeding after removal and infection at the area of removal. Your veterinarian can identify if this is just a skin tag and remove it using a scalpel and may place sutures to close the skin. If they are worried that it may be a cancerous lesion it may be sent out for a biopsy.
