Puppy Growth Chart

Monitoring Weight & Height

Puppies grow rapidly during their first year, but growth rates vary significantly depending on breed size. Small breed puppies mature quickly, while large breeds can continue growing for up to 18–24 months.

This puppy growth chart shows typical weight and height development across small, medium, and large breed puppies to help you understand what to expect as your dog grows.

Tip: If you're viewing this chart on a mobile device, zooming out or rotating your phone horizontally may make the tables easier to read.

How to Weigh a Puppy

Monitoring your puppy’s weight helps ensure healthy growth and can help identify feeding or health issues early.

Step 1: Use a Household Scale

For small puppies, place them directly on a digital scale.
For larger puppies, weigh yourself while holding the puppy and subtract your weight.

Step 2: Weigh Regularly

Puppies grow quickly, so weighing them weekly during the first few months helps track healthy development.

Step 3: Compare with Breed Size

Compare your puppy's weight to typical growth ranges for their breed size category rather than expecting an exact match.

How to Measure Puppy Height

Puppy height is measured from the ground to the withers, the highest point between the shoulder blades.

Place your puppy standing naturally on a flat surface.
Locate the withers between the shoulder blades.
Measure vertically from the ground to this point.

This measurement is often used when estimating adult size or choosing equipment like crates and harnesses.
