More: Harvey suffers from severe anxiety over squirrels and birds. He spends all day in the back yard with his favorite toy, which is a five galling bucket, and chases any bird or squirrel that he sees. He also chases any kind of bug that fly’s by. I decided to take him duck hunting thinking if he saw the ducks fall, he may go get them. On his very first hunt, i had him retrieving ducks within 30 minutes.
