Ive heard some guys say they dont run their dogs with collars because they dont want them to get hung up on something. I keep collars on mine all the time whether its in the pen or running. I ran yesterday and had a split. Two dogs took off on a different track that is on property that I dont have access to or permission to run on. Since the other 4 were still running where they were supposed to I figured Id give em a few minutes and theyd circle the rabbit back. Looking back I think it was some kind of off game (probably a deer) cause they didnt come back and they got out of hearing. I called to em and toned em with the e collar (which also has a name tag) and they didnt come back. I drove around on my 4 wheeler and couldnt find em then went and got my truck and drove around the roads surrounding the property looking for em. I finally found one of them in a neighbors yard just down the road but I still couldnt find the female that went off with him. At 11 pm last night my cell phone rang and it was a lady just across the street from where I found the one and she asked if I was missing a beagle. :whew: I had already left for work but my loving and understanding wife who had already gone to bed went and picked her up for me and put her in the pen. That aint the first time Ive gotten a dog back like that and its the main reason I always keep a collar on a dog.
