This could be a few different things. It may be a cyst or it could be a growth that is concerning. Without actually seeing the growth I can't really tell you exactly what it is. I always recommend taking an animal to the veterinarian that has a growth to have an aspirate performed. This may give an answer as to what exactly the growth is. To get the definitive answer on what this growth is Blackbear would need the growth removed and biopsied. Thank you for using Petco Pet Education Center, formerly Petcoach.
