I think it was very reasonable of your vet to inform you of the problem and recommend other testing. It sounds like the vet is most suspicious of liver shunt that is very common in the breed and wants to check the bile acids as a way to see if that could be causing the clotting factors to be off. I think an immediate referral to a specialist is great advice. She may need an ultrasound or other diagnostic type of testing. A specialty hospital may be more comfortable to spay her as the hospitals usually do more high risk type of procedures. Please keep us posted.
