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.
At what age is a chihuahua puppy able to hold his potty thru the night? At what age is a chihuahua puppy able to hold his potty thru the night? From my experience, a chihuahua should be able to sleep through the night at around 6-7 months. But this is highly individual, just like people. Some people, no matter how old they are, have to get up several times a night to go to the bathroom. The same is true for chihuahuas.
