Bambikiller,

The vet did say it could have been something he drank.

Ed,

Don't take this the wrong way, but I disagree with you and so did my vet. Not only do I start working my dogs the second week in June -- in preparation for the impending seasons -- but I know the signs of heat stress. If it's too hot, we don't hunt, hunts are cut short if it gets too hot and I always have plenty of water on hand. I think it made it to 81 degrees Wednesday and the dogs ailments were about two-hours into the hunt. Temp may have been upper 70s at that time. Appears everything points to some kind of poisoning. Like I said, I'm always aware of the dogs well-being under such circumstances and even more so with what happened in SD last year. I do thank everyone for their imput.
