Oh boy. Wags went to get his teeth cleaned today and he had some preop bloodwork done which caused his vet some concern. It seems his blood was coagulating much too quickly, so more blood was sent off to a lab for four additional tests - to the tune of a $400+ bill.
While we wait for the labs to come back, the vet told me what he anticipated: Immune Mediated Hemolytic Anemia, which basically means his immune system is attacking his own red blood cells. I'm just a tad bit terrified.
