Adults First: Why Therapy, School, and Care Dogs Should Wait Until Age 2 Before Starting Work

Dogs who work with people need time to mature. That’s why therapy dogs, school dogs, and care dogs should wait until they are at least two years old before beginning their professional work.

Why Therapy, School, and Care Dogs Should Wait Until Age 2

A young mind is eager to learn, but it’s also vulnerable. For dogs working with humans, maturity is the key to safety, well-being, and sustainable work.

It’s easy to get carried away. We see a social, happy, and seemingly cooperative puppy or adolescent and think: This dog was born for the job!

The temptation to start early is strong. But when it comes to dogs intended for roles as care dogs, therapy dogs, or school dogs, patience isn’t just a virtue, it’s essential.

Our professional recommendation is clear: 

The dog should be emotionally mature and fully developed before beginning work.

What Does “Emotionally Mature” Mean?

While physical maturity happens quickly, emotional and mental development takes longer.A dog is rarely emotionally stable enough for demanding animal-assisted work before around age two.

At this age, key developments have occurred:

• Stable stress management: The ability to handle unpredictable situations and challenges.

• Self-regulation: The skill to calm down after excitement and manage emotions.

• Established personality: A mature dog has a consistent personality, making it much easier to assess whether it truly enjoys social interaction—or merely tolerates it.

Distinguishing genuine enjoyment from mere tolerance is vital for both welfare and work quality.

The Great Challenge: The Puppy Mask

Assessing how much social and emotional strain a puppy or young dog can handle is extremely difficult, often impossible, until it’s too late.

Why? Puppies and adolescents are in constant development and are biologically “programmed” to adapt to their family and surroundings as best they can. They do their utmost to cope, even when they’re actually experiencing stress, uncertainty, or overload.

An adult dog, however, has a more stable behavior pattern and clearer signals. This makes it far easier for us to read the dog’s true motivation, confidence, and tolerance before introducing it to a work environment.

When Do Stress Management and Self-Regulation Develop?

Just like in humans, a dog’s ability to handle stress and regulate emotions develops gradually:

• Puppy: Reactions are driven largely by impulses. Puppies become overstimulated quickly and take a long time to calm down.

• Adolescent (approx. 6 months to 2 years): As the brain and hormonal systems mature, the dog becomes increasingly able to adjust behavior and regulate emotions. This is also a vulnerable period when many owners notice temporary changes in confidence and social behavior.

Experience plays a key role:

Dogs raised in predictable environments with gradual exposure develop better stress tolerance. They learn that they can influence their surroundings and receive support when uncertain, fostering deep trust in humans.

When the dog reaches adulthood, it has the stable emotional reactions and self-regulation needed to cope with varied environments and human interaction.

Did You Know?

Young dogs often react more strongly to stress than adults. Their brains and hormonal systems are still developing, and it takes time to learn how to calm down after excitement.With consistent human support, the dog gradually learns to manage and regulate its emotions.

The Consequences of Overload

Putting a young dog into work before it’s ready can seriously harm its welfare and long-term potential.

Dogs that start too early often show signs of lasting stress effects as adults, such as:

• Social withdrawal: Avoiding contact with people.

• Emotional overwhelm: Easily stressed or insecure in social situations.

• Learned helplessness: Giving up in challenging situations after learning that their efforts don’t help.

This not only reduces quality of life but can also prevent the dog from functioning well as a family pet or professional therapy, school, or care dog.

A secure and stable foundation is the safest path to a long and meaningful working life.

Building a Bridge: Safe Acclimatization Without Work

Does this mean the young dog should stay away from its future workplace?Absolutely not. Allowing early, positive exposure to the environment is beneficial, as long as it’s on the dog’s terms and without work expectations.

The goal is to build confidence, curiosity, and trust.

The young dog should become comfortable with smells, sounds, people, and the overall atmosphere, without pressure to perform.

5 Steps for Safe and Positive Acclimatization

1. Focus on safety: Let the young dog observe from a secure place (on your lap, between your legs, or on a mat). It should be able to see and hear without having to handle everything alone.

2. Start calmly: In the beginning, simply sit together and observe. Let the dog process impressions at its own pace. Withdraw gently if it shows discomfort.

3. Gradual expansion: Once confident, allow the dog to explore the room.

4. Avoid distractions: Ask colleagues not to greet the dog initially. Too many impressions at once can create stress. Introduce new people gradually.

5. Short and positive exposure: Keep visits brief and end while the dog still feels secure and curious.

Important: Young dogs should not interact with clients, students, or residents during this phase. These are “observation visits” only.

An Investment in the Future

By waiting until your dog is emotionally mature and using the time for gradual, positive exposure, you build the three cornerstones of a good working dog: Safety, Curiosity, and Trust.

Waiting for maturity isn’t delaying progress—it’s laying the strongest and most sustainable foundation for a long, meaningful working life.

Scientific Foundation

Research shows that stress management and emotional regulation develop gradually toward adulthood.Young dogs have higher physiological reactivity and longer recovery times after stress, while adult dogs show more stable response patterns and adaptability.Security, predictability, and human support are essential for building resilience and ensuring that the dog experiences its work with people as positive and meaningful.
