Beagles train themselves, find a weedpatch with alot of rabbits and take your pup there every day you have spare time, had beagles for 40 yrs and never used beef fat, hot dogs or whatever if the dog has hunt in him when he jumps a rabbit or 3 he will get excited and chase by sight, after he loses sight then instinct takes over and the rest is history... dogs are like people the more they do something the better they get at it, if the owner sits at home on the couch and watches tv during free time then its not the dogs fault when the season rolls around and the owner is disappointed in his performance... male dogs usually take a bit longer to come into their own and females can get their feelings hurt alot easier if you yell at them too much.
Bar none Beagles are one of the most loyal hunting companions there is but their nose dictates their life and gets them into alot of trouble if left to run free with no supervision.
