They can get dehydrated. The only time I would pull water up would be around 9:00 pm, I have 4 dogs in the house and they drink water all day, but, at night, they really hardly ever drink any. I would leave the water down all day, at 12 weeks the pup will probably pee 10-15 min after drinking. I sure wouldn't be only giving the puppy water 2 times a day |
