Has anyone out there run across this?..
Three year old male, found comatose in a fenced yard in the middle of 43 acres(no outbuildings close by, no availability of poison of any kind). The emergency vet did blood work, and every test indicated antifreeze poisoning (ph.8 - calcium oxylate crystals and blood found in the urine at catheterization). He went into cardiac arrest and the vet was unable to save him.
He had not been out of his compound for more than a week previous, and there was no way he could have accidentally gotten into anything. His mother was in the compound with him and had no symptoms. There were no containers in his yard, and no indication of his pulling something into the yard. He was quite civil and would not have accepted anything from a stranger.
My local vet said there was a remote chance that it was idiopathic acute renal failure, but I have never heard of this in such a young dog. There is no history of kidney or heart problems in his background(and I know the last 3 generations personally).
If anyone is aware of another cause for this, I sure would appreciate your taking the time to check in with me. I know there's alot of combined experience out there! I am unwilling to accept that someone somehow came onto my property and poisoned my dog, without a container, and without affecting the other dog, but for the lack of another explanation...

I am so sorry for your loss!

I would definitley have an autopsy done by a university (like Purdue, etc.) and find out what else was going on with the dog.

Is it possible that someone could have put poison in a hunk of meat and tossed it over the fence and only that dog ate it?? I worry about things like that with my own dogs. People are warped.

Let us know what the outcome is.
