If you want a second opinion, there's no harm in it. Just choose the second vet carefully. I've had as many as five opinions on a major surgery. No one minded. My primary vet is an Ivy League narcissist and he didn't care. :0) Vets are busy professionals.
Finnigan is gorgeous. I hope you have a peaceful resolution to the situation.
