Sadie will be 2 years old on June 3.  I'd wouldn't be telling you the truth if I said she doesn't stress me out sometimes.  She is non stop, all the time!  She finally settles down about 9-10 pm and will sleep until about 7am without a problem. But watch out after that because her battery is recharged and she's ready to go.  I'm retired, 50 years old and active, so I have plenty of time to walk her, take her for swim, etc.  I take her with me on every walk, usually three times a day.  We have a throw toy that she loves to fetch and it goes on almost every walk, so in addition to the walk, she runs after that after I throw it dozens of times.  Now that summer is here, we will take her to Lake Superior to run on the beach and swim. She is always in the yard with me when I am outside, but nothing seems to tire her out.  I know she gets tired, but will not sit or lay down for what appears to me as if she is afraid she will miss something.  My wife and I have actually seen her fall asleep on her feet.  She does have a 25' x 30' outside kennel we put her in from time to time and that is the only time she will lie down.  We bought enough fencing to build it this big thinking she would run around inside and tire herself out some, but she doesn't.  All she does is lie down in there, but the minute you take her out, run, run, run. I also have a 60 cable tie-out where we put her sometimes.  Same thought there, that she would run back and forth and exercise herself.  Nope!  The ironic part about all this, is when I have her in the yard with me, she will take one of her toys and run and play with it on her own.  She will do this for as long as you let her, but put her on her tie out or in her kennel with the same space to run and the same toy... nothing.  She's a great dog, but she is wearing me out.  If she is in the house she is always pacing and going to the door, then back to us and then to the door.  This is to encourage us to take her out.  Guess I'm just venting now.  Anyone else have this problem... the dog that can never get enough exercise?

Nothing more to add except routines help too. If you want some down time build that into a routine so Sadie expects it. They thrive under routines and it sounds like you have built a routine around allot of activity and she knows it. You can't tire them out physically, so work on the mental too. Good luck!

My older GSP never stops moving either. For instance this morning she wakes up and I put her out of the bedroom and close the door as I was not ready to get up.  I can hear her making circles around the dining table the whole time.  The only time that I get peace from this is if she has a chew and no one in the house is outside or heading to the door to go outside, or if she is crated in the car or at an agility trial.  Funny that when she is in her crate at a trial, she is all relaxed in her crate until you open the door!

I agree that a routine is best.  She knows they get to do something early in the morning and then once again when I get home from work.  And of course, I do go to training class at least twice a week, so then she gets a little extra work and attention from me.  So she is better, never really stops moving during the day, but it is more subdued as I think that she is as patient as she is going to get until its her time to play.
