Small dogs are a popular choice for people living in small spaces, young families and people who simply want a companion they can pick up or easily manage on their daily walks. But with so many different small dog breeds available, it is hard to work out the right doggo for your household.
We’ve chatted with Dr Russel Barnett, Regional Clinical Director at Greencross Vets about what you should consider before buying a small dog, and all that it’ll entail.
When welcoming a small dog into the family, you can expect them to be “affectionate, loyal and very people-oriented,” Dr Barnett said.
“Despite their size, many have big personalities and can be highly intelligent. Like all dogs, they benefit from regular exercise, early socialisation and consistent training to help them develop into well-behaved companions.
What is considered a small dog?
Small dog breeds are generally defined as dogs that weigh under about 10–12 kg and stand less than around 40 cm tall at the shoulder. These compact companions are often grouped into the toy and small breed categories.
Their smaller size makes them popular with people who live in apartments or smaller homes, and many small breeds adapt well to city life. Some are energetic and playful, while others prefer a calm lifestyle with plenty of time relaxing beside their owners.
Many small dogs also live longer than larger breeds, making them long-term companions.
What is the most popular small dog breed of 2026?
The dog breed taking the top spot in popularity this year is no surprise.
“The Cavoodle, a cross between a Cavalier King Charles Spaniel and a Poodle, continues to be one of the most popular small breeds in Australia,” Dr Barnett says.
“They are loved for their affectionate nature, intelligence, trainability, and relatively low-shedding coat.”
Why do people opt for a small canine breed?
They’re a great choice for first-time owners and adaptable for any space.
“Small breeds that are friendly, adaptable, and easy to train are usually best for first-time owners,” Dr. Barnett said.
“They adapt very well to apartment living. Their smaller size means they generally require less space, smaller food portions, are easier to travel with when needed, and many are comfortable living indoors as long as they receive daily exercise, mental stimulation and regular walks.”

Which dogs are best with seniors?
While all small dog breeds are much easier for seniors to look after than a larger dog breed, some are more suited temperament-wise.
Dr Barnett recommends, “Smaller companion breeds such as the Maltese or Shih Tzu are often well suited to seniors because they are loving, loyal and enjoy spending time close to their owners.”
How long do small dog breeds often live for?
“Small dog breeds generally have longer lifespans than larger dogs,” Dr. Barnett said. “Many live between 12 and 16 years, and some can live even longer with good care, nutrition and regular veterinary check-ups.”

“Some health issues occur more frequently in smaller breeds,” Dr. Barnett said.
