Beagles are known to be intelligent, however, it's essential for their training and education to start as early as possible or these dogs can become wilful and unruly. On the upside, Beagles are always eager and willing to please and as long as they are given the right sort of guidance and direction from an early age, they grow up to be well-rounded, obedient dogs.
Beagles need to be handled firmly, but always fairly and their training needs to be consistent throughout their lives. Any unwanted behaviours have to be nipped in the bud, gently yet firmly and this includes their tendency to bark.
