I have 2 female Scotty dogs. Within the last week, I have noticed a white 0.5" worm like grown near the neck on my 12 year old, and today found one on the neck near the shoulder on my 6 yr old. The 12 yr old also has one on her ear that I just found. They have never had these before and for both of them to now have them at the same time is a concern to me. Does anyone have any experience with this type of grown?
