Thanks for the additional information. It is helpful.
Dogs need about a cup of water for every 8 pounds of body weight every day. a puppy needs a little more but if your puppy is drinking a lot more than that every day, then she may have a urinary tract infection. Frequent urination is a symptom but at this age, they urinate all the time anyway, so that would not really tell you much. She still needs at least a rabies shot most likely so get your vet to do a urinalysis when you go it to see if there is an infection causing her to have problems holding her bladder.
I'm going to give you a site on crate training but basically the dog is in a crate just big enough to lay down and turn around in. You take the pup out when they wake up, eat, drink, play (even if just for a few minutes) and before they go to sleep. This might be once an hour or several times an hour depending on what you are doing. Pups urinate all the time though they are a bit better at 12 weeks.
IF the dog does not have a urinary tract infection, you can then give food and water on a schedule. Of course, you will need to give water more often than food but offer the pup water at specific intervals. Keep track of when you feed the pup and give water. Then track when the pup eliminates. After a day or two you will see a pattern and then you can move the times you feed and/or water so the pup can be outside at those times she most likely will need to eliminate. That allows you a better chance to reward her for eliminating outside. I'd use a high value treat like a hot dog sliver.
Most states require the rabies vaccine be given between 3-4 months of age, so if she still needs this, I'd take her in and have her checked for a UTI if she is indeed drinking much more than she should be. The other option is to leash her to you and if she goes to squat down, give a short tug on the leash and a firm "NO" then take her out and wait until she elimiantes outside and reward her.
