I was recommended this by a friend with a fellow nervous Shih Tzu. Odie was always very good in the car, but over the last 18months he started to shake and pant erratically which was horrid to watch. So I tried this he has 20mls twice a day (morning and night) into his meals and we have taken him on a few small trips in the car and also changed him from a dog booster seat to a sleep pod harness and he is now so much happier in the car, he’s been on the serene-um for four months now, he loves the taste which is fab because he hugely fussy with food. I’m so happy with his progress and now have no worries about our long trip to the Lake District later in the year. We will be keeping up with the serene-um long term. I definitely recommend it to everyone and it definitely needs to be used long term to see the affects, not the sort of product to give you the effect you need in a week.

No idea if this works or not as my dog simply refuses to take the drops - as soon as he sees me approaching with the bottle, he goes running! Maybe this product is better in tablets.
