Question

Quizplus · Accepted Answer

Weighing and measuring the puppies every week for several months strikes a balance between obtaining sufficient data to observe growth trends and being practical in terms of the time and effort required for the study. Daily measurements would be excessive and not significantly more informative, while measuring only before and after a period of several months would not provide enough data points to analyze the growth pattern effectively. A study duration of at least 3 years would be impractical and unnecessary for observing initial growth patterns in puppies.
