Fluffy Puppies hold a special place in the hearts of small dog enthusiasts. From their initial stages as tiny, curious beings to their transition into well-rounded adults, small dog breeds embark on a remarkable journey. This blog will take you through the significant dog growth milestones and provide essential puppy care tips, emphasising the importance of understanding pet development. Whether you’re a seasoned dog owner or a novice, it’s crucial to comprehend these stages to ensure your puppies grow into healthy, happy adults.

Physical Growth from Puppies to Adults 

Physical growth in small dog breeds, from puppies to adults, is a truly fascinating process. These small canines generally reach their full size and weight between 10 and 12 months of age, although some may take up to 16 months to mature completely. During this journey, it’s paramount to provide your fluffy puppies with the right nourishment and ample exercise. If you’re unsure on the exact needs of your puppy, most registered breeders will be able to provide you with information.

Birth to 3 Weeks: Puppies Begin growing

This is the inception of their life journey, a time when puppies are entirely reliant on their mother for warmth and nourishment. They spend most of their time sleeping and feeding, nestled together for comfort and protection. These initial weeks are crucial in the development of physical and emotional bonds.

3 to 6 Weeks: Unveiling the Transition from Puppies to Adults

Around the end of their first month, these small wonders start to open their eyes and ears. Their newfound sensory abilities allow them to perceive and interact with the world around them. This marks the initial shift from puppies to more independent beings, as they crawl and explore their immediate surroundings. It’s a period of awe-inspiring curiosity and discovery for these small dogs.


6 to 12 Weeks: The Adventurous Journey to Adulthood

As a registered cavoodle breeder, our fluffy puppies are fully mobile, moving with grace and energy by the time they are ready to be sold to a new home. They also learn basic commands and begin to understand the world better. The transition from puppy teeth to adult teeth is a symbolic turning point in their journey, indicating their progression toward adulthood. It is during this period, that pet care is crucial.

12 to 18 Weeks: Adolescence – The Peak of Development

Adolescence brings boundless energy and curiosity. Training during this period is essential to help these small dogs develop good habits. It’s a time of accelerated learning, and the foundations for their adult behaviour are being laid. In this phase, bonds between you and your puppy become even stronger. For small dog breeds, such as cavoodles, this is an incredibly playful period.


18 to 24 Months: Reaching Full Adulthood

At this stage, most dogs, small and big, have reached their full size and weight, signifying their readiness to embrace adulthood. They are now self-sufficient, fully grown dogs, prepared for a life of companionship, adventure, and love. Don’t worry though, Cavoodles and other small dog breeds don’t grow too big, even in adulthood!

Mental and Emotional Growth

Beyond their physical development, puppies experience significant mental and emotional growth during their first year of life. This period is crucial in their development, shaping their interactions with other dogs and people and defining their unique personalities.


Socialisation: A Vital Component of Pet Development

Socialisation from a young age is key. Exposing your puppies to different people, places, and situations helps your small dog become comfortable in any environment and interact positively with other dogs and people. The bonds they form during this period can last a lifetime, influencing their behaviour and relationships with others.

Basic Training: Laying the Foundations for Adulthood

Basic obedience training is fundamental in their journey from fluffy puppies to fully-grown adults. Teaching toilet training and essential commands, such as sit, stay, come, and leave it, not only helps them understand what’s expected but also makes them more manageable and safer. Consistency and positive reinforcement are keys to successful puppy training. This stage sets the groundwork for a well-behaved, well-adjusted adult dog.

Regular Exercise: Fueling Mental and Physical Growth

Small dog breeds may be compact, but they require regular exercise to stay both mentally and physically healthy. Aim for at least 30 minutes of exercise per day to keep them happy and well-balanced. Engaging in play, interactive games, and daily walks not only provides physical exercise but also mental stimulation, preventing boredom and potential behavior issues.

Love and Attention: A Vital Component of Puppy Development

Fluffy puppies thrive on human companionship. Your presence, love, and attention are vital for the emotional well-being of small dog breeds (and all dog breeds). Spending quality time with them every day, offering love, affection, and cuddles, is essential for nurturing their emotional growth. A strong bond with their human companion can enhance their emotional intelligence, making them more perceptive and responsive.



Understanding dog growth milestones and pet development is critical for providing the best care for your puppy, ensuring it grows into a healthy and happy adult. The journey of small dog breeds from playful, curious puppies to well-adjusted adults is a rewarding one. By being an informed and attentive owner, you play a pivotal role in shaping your dog’s life and creating cherished memories filled with love and laughter. Whether they are your furry friend, confidant, or playmate, the journey of raising a small dog, such as a Cavoodle, is a rewarding one, full of love, laughter, and cherished memories that last a lifetime. 


As you embark on this journey, remember that understanding the unique path from a small puppy to adulthood will make it all the more enriching and fulfilling.
