Yes, Cardigan Welsh Corgis bark quite a bit, but their barking tendencies can vary from dog to dog. They often bark during play to express excitement or engage with their family members. Cardigans are naturally alert and protective, making them good watchdogs. They might bark to alert their pet parents of strangers or unusual sounds. If they do not receive enough mental and physical stimulation, Cardigans might bark out of boredom or anxiety. Regular exercise and engaging activities can help manage this behavior.
