Just wanted to report in that after several days of totally NOT being himself, Herc sprang to life tonight! He ate, actually asked to go outside twice, ran around the house and brought us his tennis ball to play. I cried with relief, he has been SO out of sorts - It had me totally freaked out! I know his physical wounds will heal, but for his entire demeanor and personality to disappear for a few days had me a nervous wreck! Hopefully he is on the road to recovery and the worst is behind us.
