Growing up we had fiest (tall type if there is such a thing ) . Living on the Tombigbee river ther were never a shortage of squirrels . I guess our poor training made our dogs hard headed . lol they would not stay when you killed the squirrel . Not gun shy wise but it was off to the next one . Our dogs ran free always . I think if it has " it "in him he ill tree , given opportunity . We had rabbit dogs that ran free as well . Time in woods makes a dog . Many mornings I got on the school bus and " Rowdy "(WAGON TRAIN / CLINT EASTWOOD ) was treed in the back yard .
