Every year, small businesses worldwide lose thousands of dollars to theft, with market stalls and open-air shops often being the most vulnerable.
In many regions, store owners have long relied on dogs as part of their security strategy. The right dog is not just a deterrent to troublemakers but also a trusted companion who adapts to a busy marketplace.
While some breeds are better suited to family life or farm work, others excel in environments filled with movement, strangers, and constant activity. Their presence alone can make customers feel safer and keep unwanted visitors away.
This article looks at the dog breeds that combine vigilance, adaptability, and calm judgment to protect market spaces effectively.
