When introducing your dog to a new dog park, ensure they are well-trained in basic obedience commands like 'Stay' and 'Come.' Start by observing the park's atmosphere and the behavior of other dogs. Choose a time when the park is less crowded, such as weekdays or early mornings. Keep your dog on a leash initially and gradually introduce them to the off-leash area while closely monitoring their interactions with other dogs. Look for friendly and well-behaved playmates for your dog to socialize with, and be prepared to intervene if necessary to ensure a positive experience for everyone.
