Dog lovers are being urged to stop petting unfamiliar dogs in public, as it can cause anxiety for the animals. Sarah Jones, the founder of My Anxious Dog, emphasizes that every dog should be treated as a potential 'do not touch' unless the owner gives permission. Her rescue Cocker Spaniel, Bella, who is nearly 14 years old, wears bright yellow caution gear to signal her anxiety to others. Jones launched the #DogsInYellow campaign to help anxious dogs communicate their need for space without growling or lunging. At a recent event in Burley, Hampshire, she explained that yellow is recognized as the official warning color for caution. She advises that if someone wishes to pet a dog, they should first ask the owner and stroke the dog under the chin rather than on the head. Jones stresses that even those who consider themselves good with dogs should respect that an unfamiliar dog may be scared and need space. The campaign aims to raise awareness about dog behavior and promote safer interactions in public spaces.
