Harold;
Glad you and your pup were reunited. I can just imagine what was going through your head. EIHDH is a reality and one of my best hunting buddies is a Veterinarian and informed me of it 20+ years ago. I've encountered it twice with my dogs over the years, once with an English Pointer and just recently with one of my labs. I always carry a small squirt bottle of honey in my vest and if I see any sign of it I heel them, give them a shot of honey, then let them chill for a few minutes. Most guys don't hydrate their dogs enough so if there is'nt a pond or stream nearby I make sure they get a drink every 30 minutes or so. One word of caution though- If you come upon a pond or ditch covered with green or blue algae DO NOT allow them to lap up water from it. It can be toxic to them. My Ex used to say to me that she thought I cared more for the dogs than I did for her. I guess she was right because I still sleep with the dogs every night and they never complain about my snoring.
