I think both kinda are normal. Hera is on the go almost all the time, sometimes she will make you believe that she is tired and ready to take a nap on the couch, but as soon as someone as much as take a step she is up and ready to gooooooo. She sleeps okay during night, but she is awake all day lol...
Galahad on the other hand is sleeping most of the time, he does a play raid and then back to sleeping, he goes from the couch to the bed, then up and walk around for awhile, check if there have come any more food in his bowl and then back to the nappi nap.
Zeus is something inbetween the two. He can sleep if nothing goes on, but if there is something he is interested in, he can stay awake a whole day
So I think I have one of each and one inbetween, I think dogs are just like us, some are more hyper and active then others, some are totally cool and chill all the time. The one thing all my dogs have in common though, is that they like to sleep in, in the mornings, and I cant say I am complaining hehe
