sounds like you've had some pretty interesting nights for the last 3 months. hehe we had them too (our female V is now 7 months) and we still have them. what we try to aim for is wear her out daily and monitor her nap times throughout the day and if you get her on somewhat of a schedule then she should start to get in bed the same time you want to. of course you can't expect her to hold her bladder as long as you can, so you will more then likely have to get up at least once during the night to let her out. do you crate her or does she sleep with you?
as far as her growth plates..
we had troubles with this as well because we live in an apartment in the middle of a big city and although we live in a fenced in one building complex with an attached fenced in parking lot, we only have less than half and acre total of grass for her to potty and run. so we do let her run freely around on the pavement of the parking lot. we end up throwing her kong wubba for her on the pavement and she runs nearly full speed out there. i don't think it has really negatively affected her growth plates. and the other thing is she had a pediatric spay (they say the big thing about spaying so young is that the dogs growth plates close at a much slower rate) and so if it was bad for her..you'd think she wouldn't be on a normal growth rate as of now; considering she's been running off leash on pavement since she was 2 months. i think the treadmill might actually be better than running on concrete or pavement because it has at least a little more give than hard ground. how tall is your girl now? and how much does she weigh?
