Do most people with hold water after a certain time?
No, They don't! Restricting water intake can be very dangerous, even life threatening, especially in young puppies.
There are syndromes associated with excess water intake. Polyuria and Polydipsia. there are bladder infections in females, there can be many reasons for excess water intake and or urination. Unless you're positively certain that her water intake is adequate, don't restrict her from water.
Your puppy is only 11 weeks old, she is going to have to go potty frequently, even in the middle of the nite. As she gets older, even just a few weeks, she will get more control of her bladder, and be able to hold her pee longer. Stick with it, and she'll be fine. As you extend the interval she'll adapt her schedule, to a point, around yours, and you'll both be sleeping through nite. She may also just still need psychological reassurance and that is causing her to not be sleeping through the nite.
An internet search on the effects of blood plasma and volume in the presence of chronic dehydration/deprivation of water in mammals will yield a tremendous amount of info on the subject.
I know the exclamation point in my opening sentence is a bit strong, apologies upfront, but a dog needs an average of 1oz of water per body weight pound. This an average energy adult dog. Puppies, young dogs, and working breed dogs will require even more, sometimes a lot more. Limiting the intake during certain time periods should be carefully considered.
