Certain dog breeds can have a higher predisposition towards aggression or strong prey drive, which may make them more likely to chase or harm cats. These breeds often include terriers like the Jack Russell Terrier, high-energy working dogs like the Australian Cattle Dog, and sighthounds like the Greyhound, due to their instinctual drive to hunt or chase smaller animals. However, it's important to note that individual temperament, training, and socialization from a young age play significant roles in how a dog interacts with cats.
