We're going to do an ultrasound tomorrow to get a better idea of what's going on and if we can medicate him, but the short form is, he's got an erratic heart rate ranging from 35 BPM to 165 BPM and could go into ventricular fib at any time.
So he could have another six months, or we could lose him tonight. Which is, you know, not unexpected. He's an old man, and this is how mastiffs go. And it beats the stuffing out of cancer or kidney failure.
