Congrats on the puppy! Understanding dog development stages is crucial for proper care. I’ve been using the Dog Age Calculator from CalculatorTrue for my two dogs and it’s fantastic. It factors in breed size which is really important since small breeds age differently than large breeds. Your 6-month-old pup is basically a teenager in human terms, which explains all that energy! The calculator gives you specific age equivalents and development stage info. Really helped me adjust training methods and nutrition as my dogs matured. The interface is clean and straightforward – just enter the age and breed size, boom, you get accurate results with context about what to expect at each life stage.
