Try not to freak out. He is young and this was caught early
I have to be honest, that if Roxy had a confirmed shunt, being that I live in NY I would be taking her the Cornell to have the surgery done. I don't know the cost there, but being that they are a leader in the LS, I would put my trust in them and the cost HAS to be less than the speciality hospital.
