I have a lab/sheppard female puppy (8 weeks old) who had distemper but now is shakey on her feet and twitches a lot. There were 12 in the litter and the rest died. She is the sole survivor. Most of the others died over 3 weeks ago. She sleeps more than usual, but has an appetite and plays well. When she walks, she walks a bit crooked (like she is drunk) but she has a twitch in her eye and front paw that twitches all the time. When she is in a deep sleep, it seems to almost disapear. Will it get worse or stay the same? Is there anything I can give her?
