Puppy Development Milestones
Newborn Shih Tzu
Just as in human development, puppy development milestones follows a very predictable sequence of steps, although there is no widespread agreement on the exact ages that these milestones occur. Small dogs grow and develop quickly and often reach maturity before larger breeds.
Puppy development follows a predicable path yet each puppy is unique and each breed is slightly different at the various stages of development. The old rule of each year of a dog’s life is equivalent on seven years for human is not completely accurate.
For most small dogs, including the Shih Tzu, the average life span is approximately 15 --16 years. Small dogs mature early and females often have their first heat by the age of 6 or 7 months. By the age of 12 or 13 months, they are often ready to be bred.
Many changes take place in the first year of a Shih Tzu Puppy's life.
Puppies go from a relatively helpless neonate who cannot see or hear or eliminate by himself to a fully grown, agile, sexually mature adult all in less than 12 months.
When do all of these changes take place?
There are seven recognized stages of puppy development:
Stage One: 0-3 Weeks
Stage Two: 3 to 7 Weeks
Stage Three: 7 to 12 Weeks
Stage Four: 12-17 weeks
Stage Five: 17 to 40 Weeks
Stage Six: 40 to 52 Weeks
Stage Seven: 1 year and older
We will first look at puppy development week by week.
