9. Not setting boundaries

Just as you wouldn’t let your toddler wander unsupervised in your home, setting boundaries for your dog is equally important. “Boundaries keep your dog safe,” says Melony Phillips, a certified professional dog trainer and owner of Delightful Dog in Marietta, Georgia. She suggests letting your dog drag a six-foot-long leash around the house. “When she ventures into an off-limits area, step on the leash. When she pauses and looks back at you, offer a reward and redirect her,” she advises. “Just don’t tug on the leash—it’s a teaching tool, not a control device. When you’re not around, ensure her success by blocking access to restricted areas.”
