Yesterday I panicked, because while walking my dog he just collapsed...completely without warning.
I couldn't pick him up(93 pounds) so I called my sister and practically collapsed myself when she didn't answer.
I waited...
And waited...
And after about ten minutes by which I was on the verge of tears he finally got up and just sat there looking very exhausted. I immediately got him home and convinced my sister to drive me to the vet and they checked him over, tested him and everything but said there was nothing at all wrong and that he was actually quite healthy for a five-year old mutt that he is.
I know I'm not crazy and that nothing just passes out for ten minutes without reason.
But we took him to a different place again and got the same response.
My mother says it could have been that he'd been over exercising or something. It makes no sense, though, since we only walk about half a mile up and down the park. Unless I'm on my bike and even then he just jogs along. At noon, I walked him up and down the same path again. Nothing. My sister picked him up right after to take him to her house while I babysat.

A little bit ago she called and said that the dog had passed out and wasn't breathing anymore.
I asked her to try and make him breathe, blow through his nose, check his heart...
She just said "no, he's gone."

I know that mostly everyone's thinking "pfft, its just a dog" and that there are bigger problems to have.
Heck, I have bigger problems if I think of them.
But I just had to put this somewhere.
