I'll tell ya, I went through this w/my Puddy so many times that I lost count. She, too, was in CRF for approximately 6 years and I'd think it was her time, then she'd perk up. They're such fighters and troopers. We are the ones who lose another life while they keep going. LOL I'm glad that you still have your sweet Filou w/you for, hopefully, a good while yet. Keep the faythe.
