Puppyhood is the first stage of a Cocker spaniel’s life, starting from birth to about 12 to 18 months of age.

In this stage, Cocker spaniels undergo rapid physical and mental development.

During these early months, it’s important to get them off to a strong start by undertaking activities, such as puppy classes, that are designed to teach your pup the basics of socialization and obedience.

This provides them with the tools to be healthy and well-behaved as their personalities develop— ultimately resulting in a wonderful companion for many years.

Still, regardless of all of this learning, don’t forget to spend some quality playtime with your pup too, after all, there’s no better way to bond and build trust.


Adolescence is the second stage of a Cocker spaniel’s life, lasting from about 12 to 18 months to 2 to 3 years of age.

During this stage, Cockers continue to grow physically, but their mental and emotional development also matures.

They may become more independent and test boundaries, but with proper training and positive reinforcement, they can still be well-behaved and obedient.

It can be a difficult time for inexperienced owners as the dog begins to assert its independence and pushes the limits of acceptable behaviour.

When your Cocker reaches this stage in his development it is similar to having a teenage human in the house, it’s important to be consistent with training and behaviour, yet fair and appreciative of this crucial stage of development in your dog’s life.

Their personalities are fully formed, and they can be quite independent.

Reaching adulthood in a Cocker spaniel’s life brings a unique set of developments.

Physically they grow and develop their signature coat, while also emerging from the puppy phase.
