Hiya.......i breed, show and judge beagles.....they are fab little dogs and very adaptable if you put the effort in to train them as all the previous posters have said........yes they are scent hounds and stubborn but CAN be trained to be 99.99% reliable..........i dont think any dog is 100% ...should you want any specific help beagle related you can always contact me off site or p'm me
good luck
Pauline
