Played fetch 2 times with him last night (15 minutes of hard running each time). He was barking to go outside this morning so I let him out at 6am (I guess he was feeling bad, we had gone out at 3am too), brought him in a little after 9am - put 2 other dogs out for 2hrs. Apparently my wife put him back out this afternoon (I did not know about that) - we went for father's day supper. Came home, daughter did not want to feed the chickens because Beau was outside, but when we tried to let him in, he did not come. Found him dead beside the dog house. No clue really why he died. Heatstroke? Poisoned Rat. Choked on something he should not have eaten? Any guess is as good as another. I think he was about 7, in good shape, exercised hard daily... No symptoms till I found him at 9pm stiff.
We have 4 other dogs that will probably get more love and attention now. One is 2x as old and going downhill pretty quickly (every time I see him sleeping I check to see if he is still breathing) - already getting a lot of extra love and attention. But Beau was MY dog, and my hunting buddy.
