Sounds like all dog to me! My dog Annie had a LOOONG childhood too, and it was indeed tiring. She wasn't even a Beagle! I think she was two before she calmed down.
I wish I could give you some advice, but it's been so long since I've had a dog that I can only reiterate what the others have said; this, too, will pass! Marbles will grow up!
On a side note, if Beagles are less exhausting than kids, I think I'm well prepared! I often have to watch my 2 1/2 year old nephew, and he is downright exhausting! I love the kid to death of course, but I'm sooo glad that most of the time he's my sisters' responsibility!
