RedactedNarrative: Came around a corner into rapids.  Canoe took on a little water and scared dog (110lbs).  The dog started toward back of canoe where I was sitting and then got hit by another wave and took on more water.  The wave knocked the dog overboard and he clinged to the right side swamping the canoe.  Float bags, jacket and totes floated downstream.  Canoe sank and was last seen by a fisherman 1 mile downstream.  The canoe was never recovered.
