A seasoned canine behavior expert, Will Atherton, reveals three dog breeds he would never own, even with his vast experience handling diverse dogs. Owning a dog offers loyalty, companionship, and daily motivation for walks, but it demands lifelong commitment and careful breed selection.
In a popular social media video, Atherton states: “These are the three breeds that I want but I’ll never have, even as a canine behaviourist that has the skill and experience to be able to manage pretty much any dog.”
1. Turkish Kangal
The Turkish Kangal hails from Turkey’s Sivas province, where breeders developed this robust guardian to protect livestock from wolves, bears, and jackals. Known for exceptional loyalty, intelligence, and protective nature, these dogs excel at safeguarding flocks.
Atherton explains: “Number one is the Turkish Kangal and they’ve been on my shortlist for probably a decade. I truly think they’re one of the most beautiful dogs on the planet. However, they are a serious dog and they don’t mix well with a normal family life.”
2. Caucasian Shepherd
Originating from the Caucasus Mountains between Europe and Asia, the Caucasian Shepherd, or Ovcharka, stands out for its massive size and strength. This breed historically defends sheep from predators like wolves, bears, and jackals, displaying remarkable courage and devotion.
Atherton adds: “The same can be said for the Caucasian Shepherd – everything about the Kangal but just times two; insanely serious and the challenge of being able to raise a really good one is something that whispers at the back of my mind every now and again. However, I take my own advice and understand that it would just be a terrible choice for my lifestyle.”
3. English Mastiff
The English Mastiff ranks among the world’s oldest and heaviest breeds, originating in England as a guard dog, war companion, and hunter. Often called gentle giants, these dogs show calm temperaments and deep loyalty to families.
Despite past ownership, Atherton hesitates due to health risks. Mastiffs live only 6 to 10 years and face issues like joint problems, heart conditions, and obesity. He notes: “Last of all is a dog that I have already had, which is the English mastiff and I would be desperate to have another one because they are an amazing pick for my family. But just how prone they are to serious health issues is just something that I’m not sure I can take the risk with again.”
The video sparked engagement from viewers. One owner shares: “We have a Turkish Kangal, we know what you mean, but we have been soooo lucky with her. We love them as a breed and would love to keep adopting more.” Another reflects: “I would love to have a Rottweiler again, but don’t think I have what it takes anymore.”
Prospective owners should research breeds thoroughly, prioritize training, and consider rescues from shelters over breeders, especially for first-time guardians.
