The designation of “puppy” typically applies to a canine in its early stages of development, characterized by rapid growth, playful behavior, and incomplete physical maturity. The point at which a dog transitions from this developmental phase to adulthood varies considerably depending on breed and size.
Understanding this transition is crucial for responsible pet ownership. Recognizing when a dog has reached adulthood impacts training approaches, dietary needs, and expectations regarding behavior. Historically, the period considered “puppyhood” was often based on observation and anecdotal evidence. Modern veterinary science offers more precise guidelines tied to physiological milestones.
