Our guys are slightly older and have access to water 24/7. All puppies are different, but a puppy can usually only hold his waste for the same number of hours as his age in months. (In other words, a four-month-old pup should not be left alone for more than four consecutive hours without an opportunity to go outside.) He can last longer at night, however, since he’s inactive (just like we can). By the time your pup is about four months old, he should be able to make it through the night without going outside. So Chubbs would be approximatley 3.5 hours. It was about 5 months for Jewel to make it through the night.
If there is increased frequency and the voided amount is only a trickle...one might suspect a UTI.
