Have you ever wondered whether it is safe to walk your Beagle on the streets without a leash? Most people will say that it isn't safe without a leash. This is because the beagle was bred to be a hunting dog with a strong and powerful sense of smell. You cannot override thousands of years of ingrained instinct that is so sharp that the Beagle is one of very few breeds that requires no training to be used for their original purpose of hunting. Hence, Beagle leash training is very important.
Be a responsible owner and do not let your Beagle off leash. When your Beagle has caught an intriguing scent, it is almost impossible for you to convince your Beagle that what you have is better and more interesting than the tantalizing smell they are going after. For the beagle, their nose rules the roost, and it takes a lot of work and effort for the you to properly motivate and reward the dog.
