I recently discovered a lump on my 4 yr old spayed Border Collie's belly, which two vets have independently diagnosed as a hernia. She has no apparent side effects and does not seem to be bothered by it. Both vets said that usually they leave hernias alone, however one said that because she is a fairly active dog (trail riding and agility), that he recommends surgery to fix the hernia. How should I decide if it is worth the risks of surgery?
