My brother once looked at my beagle and said, "You know, it's a good thing you're cute because you're SO ANNOYING!" This really sums beagles up in a nutshell.
I have had 4 beagles over the course of my lifetime and they are some of my favorite dogs. They have great personalities and tend to be very interesting, fun, energetic, loyal, loving, and sweet. They're beautiful dogs and make great pets... But they have their downsides.
Beagles also tend to be very strong willed and often challenge authority. They are very hard to train and will flat out ignore you if they feel like it. They are bred for hunting so they have strong instincts to chase down and track animals. If you let them go outside you will hear their annoying and incessant baying all night long as they chase animals through the woods. When they are on the hunt, NOTHING else matters. They are also very greedy and will whine constantly at the dinner table, and steal food when your back is turned.
Every man dies, but few truly live. Live your life to its fullest, every day as if it were your last.
