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 would use the age criteria for maximum time puppies are able to hold their bladder only if they are confined to a crate. If you had your pup in a crate then they would likely be able to hold their bladder for this length of time.However, if your pup is loose in the house with you, then I'd suggest that you'll need to take her out to potty more frequently. For example, it would be closer to every 30-40 minutes at 8 weeks old. would use the age criteria for maximum time puppies are able to hold their bladder only if they are confined to a crate.
