Also, this might be a long shot, but have they done bile acid testing on him? Liver shunts and MVD can show up in non typical ways and because they are fairly common in yorkies I think it is good to test any time they have some kind of "mysterious" symptoms. I am assuming they didn't see any urate crystals in his urine, but could he have stones? Maybe I am way off base, but might be worth asking about. |
