Like humans and animals, plants need both water and nutrients (food) to survive. Most all plants use water to carry moisture and nutrients back and forth between the roots and leaves. Water, as well as nutrients, is normally taken up through the roots from the soil.
So, for example, a 3-month old puppy should be able to hold its urine for approximately 4 hours in a pinch. This means that if you have a properly toilet trained 4-month-old puppy that, theoretically, can hold its urine for 5 hours, and you shut that puppy in a crate for 6 or 7 hours, you are courting disaster.
I think your dog has gotten into a pattern of being left out during the middle of the night. My guess is that should you ignore him he will hold it. A good rule of thumb to follow is a puppy can hold his urine 1 hour at one month, 2 hours at two months, 3 hours at 3 months, etc. One extra hour per month.I guess this could vary a bit but that is the guideline we were given when asked what to expect.y guess is that should you ignore him he will hold it.
