"Little furry things that move quickly are very interesting to a lot of dogs," Sackman told The Dodo. "That is intrinsically part of their biology and drive. That said, I think most dogs that are raised in a home with a cat learn to habituate with a cat and get along very well."
When a dog grows up in the same home as a cat, or other small animals, he gets used to the cat and doesn't see her as prey. Many dogs and cats who grow up in the same family even form incredible bonds, like Sackman's own cat and French bulldogs, who love to snuggle together.
"They will get along with a cat in the house because they've been raised together," Sackman said. "It's not a predatory situation."
