On 12-16-07 and 12-17-07 Abby started running from place to place to lie down for 2-10 minutes and then repeats. She seems to have a muscle quiver/spasm on left shoulder. I did put Seargent's tick,flea medicine on her on 12-15 and she did try to jump in a truck and fell off a few days ago, but she was fine till 5p.m. on 12-16.
