I wouldn't recommend a real bark/shock collar. I would recommend the citronella ones, they are harmless. I don't know if a collar would work for a beagle, they're vocal and that's how they are!! Buster bays, too but I don't find it annoying. I acutally like the baying, probably because I love the hounds. I guess you have to REALLY love them to deal with the baying. People who don't like it shouldn't have a hound, period.
