Went to vet, he examined her and drew blood for CBC senior panel including urinalysis and he said nothing really showed. Her cholesterol and triglycerides were slightly elevated but that's probably because she was not fasted beforehand. There were a few crystals in her urine, but that's about it.

Sooooooo, the vet thinks possibly the antibiotics she was on after her dental procedure upset her GI tract. She's never been on ANY antibiotic before, so I hope that's the problem. He gave me a probiotic called Proviable-FORTE, digestive health supplement to sprinkle on her food once a day and I should keep her on the metronidazole and tylan powder. He said to let him know how she's doing next week. He wants to repeat the bloodwork in three weeks.

So, we'll see what happens.
