My Pogo is at the vet now, we are trying to find a diagnosis.She sleeps most of the time, appetite poor, sometimes has facial twitching.When I take her out to potty, she squats and urinates, and then just stands and looks at me, she does not sniff the ground at all now.This is very unusual for her, she would normally run off.A few days ago, she had a nose bleed.Any ideas?
