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
