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.
Puppy to Adult. If youâve raised your dog since she was a young puppy, and sheâs been progressing with recommended house-training methods, your 1-year-old should be able to hold her bladder eight to 10 hours.upiterimages/Photos.com/Getty Images. An average puppy under 8 months old can hold her bladder in hours about equal to her age in months plus one. Once your puppy gets near the one year mark, however, or if you adopt a 1-year-old dog, that rule no longer applies.
