In brief: Rarely

In rare cases, I have seen a patient with dehydration have high blood pressure.
This occurs presumably because the body's response is to "clamp down" (vasoconstrict). Interestingly, in these patients, restoring the volume with IV fluids led to the blood pressure coming back down to normal.

I would go with the Cardiologist's answer of rarely. If he's seen it, it happens. The rule is no, but there are exceptions.
