Cesar Millan (world renowned dog behaviorist and co-founder of Halo Collar) addressed this issue during an exclusive interview with PureWow. While it varies by dog, Millan revealed that there’s a difference between rough play and aggression. “I suggest knowing your dog’s behavior to help stop aggressive behavior before it starts,” he said. “Dogs may lean forward, growl or even bark.”
If a situation escalates, it’s OK to step in, take a break and then reunite the pups once they’ve both calmed down. “When a dog is playing with other pups, it is also important to take a pause during playtime for a few minutes so the dog can cool off,” Millan added.
