Last night I proved to my husband how well PR works! We always have it plugged in upstairs for the cats but last night when the fireworks started (approx 8.30pm!) My two usually quite chilled labs got anxious, they were pacing, salivating, vocalising and restless. I brought the plug-in down stairs and for good measures used a pump of the travel spray on their beds. Within 5 mins both were fast asleep and neither were bothered by the fireworks for the rest of the night despite them going off until 1am.   He accepted it does work very well!!
