Definition of energy: Ari 

Seriously at 6 mos. old she is quite capable and willing to walk a total of 5 miles per day (I generally do the longest walk at night - about 3 miles I calculated it to be), multiple play sessions, and to be frank it's not enough! We don't run/jog her (unless she's off leash doing it on her own), though when she gets older my SO will (I won't. I will walk for miles, but no running thankyouverymuch). I'm still taking her swimming when I can (it's been too rainy and cold for me to stand at the beach, but I don't mind walking in the rain).
I saw someone on here uses a treadmill with their dogs - and I will admit I started peeking around Craig's list! It would be nice for mornings - I really have a hard time with mornings. Plus where it's dark out in the mornings now I'm a tad afraid to go walking on the trail (there are wild animals) hehe I'm wimpy.
She's a bundle of raw energy and I don't know how to keep up with her. I'm still worried about over doing it (though not so much anymore) and am just counting down the days we can begin conditioning her to go hiking.
How do you all exercise and keep up with your "always on the go or passed out sleeping" puppers? Have you found their off button - could you tell me where I could locate it on Ari....please? Her latest thing is 4 am wakeup calls because she is rearing to go. Needless to say her humans are not happy with this (though she is more effective than any alarm clock I have ever had)- but finding it hard to scold her because she will go to the bathroom outside when I finally get up because I can't sleep through yowling (for what it is worth she started doing this while kenneled up for 2 weeks to recoup from surgery).
In good news, I've started losing some weight due to this increase in HER energy lol and my calves are starting to firm up a bit!
