Sorry it took a few days to reply, and thank you everyone for the responces, it's been a crazy few days. They did the bile acid test on Monday, The vet didn't think the levels came back too abnormal and doesn't think that he has a shunt. He said normally in dogs with shunts they are typically smaller(Carl is 9lbs) and they have low energy, yellowish eyes(in the white part) and do a "face pressing" against the wall...Carl doesn't have any of those symptoms. The levels were only mildly high which he didn't think showed a shunt. Also, his bilirubin levels were a little high, but otherwise everything else was normal.
He was put on a antibiotic for 7 days and a liver supplement (Denamarin) for 30 days. It doesn't seem like the medications have really helped anything so far, so I have a call back into the vet to see what they think. He said the next step would probably be doing an ultrasound with a liver biopsy.
I did some research online and I'm going to ask if they checked him for hypoglycemia, I'm sure that glucose shows up in blood work but going to double check. I just can't imagine what is going on, the vet kept asking if he maybe ate something bad but he does not get any people food and I have nothing laying around or even anything toxic in my home. He is still playing, eating, going potty, doing EVERYTHING he normally does, it's just his lack of stability and wobbliness that is scary.
