Frisco has a few Cysts, but they don't seem to bother him when you press on them or anything....hey, at 17 years old, I would expect some sort of growth. Codi, is 8 years old, and is starting to develop quite a few of them....and some are nasty to look at....we are thinking of maybe doing something about the bigger ones. He had one on the top of his head...20 minutes at the vet, and $350, it was gone....now multiply that at how many he has !!!....we'll slowly get them done...between the 2 of them we are already spending close to $300 a month on special diets and meds
