Canine behaviour specialist Will Atherton has identified the three dog breeds he "rarely" encounters for training due to their low propensity for developing problematic behaviours. His insights, shared in January 2026, have ignited a lively discussion among dog owners and professionals.
The Top Three Best-Behaved Breeds
Leading the list for Mr Atherton is the Labrador Retriever, which he enthusiastically described as the "best [dog breed] in the world". He explained that the most common issue with Labradors, such as pulling on the lead, typically stems from their friendly and sociable nature, as they are eager to greet people and other dogs. According to Atherton, these behaviours are "dead easy to dial in" with appropriate training.
The second breed highlighted is the English Mastiff. Atherton praised this giant breed, calling it one of the finest worldwide and labelling its temperament as "laidback". He considers the Mastiff to be the "perfect" pet dog for the right owner.
Completing the trio is the Cavalier King Charles Spaniel. The trainer expressed high regard for this small breed, stating, "I think they're one of the best small breeds on the planet" for their typically good behaviour.
Public Reaction and Health Concerns
The revelation prompted immediate reaction from followers on social media. One commenter was unsurprised, noting, "I knew a Cavalier King Charles Spaniel would be on there." However, the discussion also turned to the breed's well-documented health issues. A veterinary nurse commented, "I got one knowing I'd have to deal with heart issues," while another potential owner admitted the health concerns were a significant deterrent.
Challenges to the Expert's View
Not everyone agreed with Atherton's professional assessment. The claims were directly challenged by some within the dog care community. One dog walker countered, pointing out that she encounters some "horrifically behaved Labradors" in her line of work. Another sceptical voice added, "He just proved that just because you work with something does not mean you're an expert," questioning the direct correlation between professional experience and definitive expertise on breed-wide behaviour.
The debate underscores that while general breed temperaments exist, individual dog behaviour is also heavily influenced by upbringing, training, and environment, making any blanket statement a topic for discussion.
