i have a beagle that has a little bassat hound in her and have never been able to get her to listen to me when i want her to come to me so i never took her out rabbit hunting with me but she will track rabbits she is now 8 yrs. old and i was wondering if i used one of my buddy'sshock collers if there is a way that i could train her some event hough she is 8 yrs. old or if she is to old to teach her some new tricks

I still a newbie to the beagles, but try this board it is loaded with info and nice people:

remember the dog is eight years old and he probably has lost some of his hearing by now. we always start new dogs when they are pups. you would be better off to whistle train him around the house first. a whistle will carry alot farther than your voice. once they learn to come to the whistle for a treat then i would move on to further training. we train ours so when they are on a hot track and we blow the whistle they know the rabbit has just ran by us. they learn to come to the whistle because the track will be red hot. when they come in i point out the super fresh track and off they go closer to the rabbit. this is a good thing to train on because when it is time to come in you can fool them to returning to you. if you move on to a shock collar never set it up any higher than you can take on your fingers. i use my pointer finger and my middle finger on the tips to test the shocking power then adjust from there. you can mess up a good dog by not using the collar the right way. never use a shock collar unless it has a warning button. it needs to have a beeper or vibrator on it. this is good for older dogs with a hearing loss. you always warn before you shock. many many times all the dog needs is a reminder with the warning. you should never shock a dog unless you can see them not responding or know for sure that it is not coming in. i have seen guys not even give their dogs time to respond before they start hitting the shock button. this is dumb because the dog may already be on the way in. by shocking a dog on the way in it really confuses the dog. shock collars are far from the perfect training tool. it takes hours apond hours of practice to get a dog working good. hope this helps a little.
