dog vs beaver

we were walking along the flooded Rappahonnock when Guy takes off. All of a sudden I see a beaver scurrying off. I think it is the first beaver that I ever saw in the wild. It was hilarious in that neither knew what the other one was or what to do. The beaver tried to swim off in a shallow area and Guy tried to chase it bouncing in the water until he realized that the tail was to be avoided. So he circled in front and got a load of the teeth. So he decided that bouncing from side to side and barking was the best strategy. The beaver just wanted to get the hell out of there. Finally, Guy backed off and the beaver swam off. I leashed Guy and on we went.
