Newfoundland Life Span

The following are the different stages of growth for a Newfoundland:


Newfoundlands are considered puppies between the ages of zero to nine months. This is the stage where you get to snuggle, carry, and know your puppy better. The puppy stage involves teething, playtime, naps, and growing.

During this stage, you must start training your Newfoundland on acceptable behavior before it gets out of hand as well as potty train.

Juvenile & Teenager

This is the adolescence stage and is between the ages of 9 months and 3 years. This is the most trying stage of a Newfoundland as they are clumsy, mouthy, suffer from selective hearing, and have awkward looks with the different shades of brown or black.

During this stage, Newfoundlands are becoming more independent as they find themselves and are full of energy. You can now teach them how to socialize, the basic commands, and even introduce them to water.
