We have a 14 year old Golden Retriever and he does get anxious when we travel during long trips as well as during our Florida summer storms. He weighs a little over 50 lbs and I gave him 3 of the treat like biscuits. He loves the taste and it takes about 30 minutes to take effect. He did not whine the entire trip, slept some, but was awake most of the time and showed no anxiety. During thunderstorms he still gets anxious, but not at all like he used to. Yes, I would recommend this item and will purchase again.
