        Currently undecided

        Not sure at the moment - I have a highly anxious, barky Collie-Cross who has been on it just under a month (but for last week have upped dose to two tablets) and so far making no difference whatsoever...But it says they should be on it consistently for 3 months so am willing to peservere and see how we go. Hoping I can come back with a more positive review then! Definitely nothing wrong with quality and the fact that he will eat the tablets is quite amazing! Value for money score is based on fact that if they don't work then the money is wasted!

        Hi Row,

        Thank you so much for this honest review and for giving our Daily Calm Supplement a go with your Collie-Cross! We really appreciate you taking the time to share where you're at with it 💚

        It's brilliant that he's willing to eat the tablets! We completely understand your perspective on waiting to see the full effects, and we think it's great that you're willing to persevere and give it the consistent time it needs. Every dog is different, and patience really does pay off on these kinds of journeys.

        We'd love to put you in contact with our in-house Behaviourist Nico who can help offer further support and guidance, please reach out to our team at woof@omni.pet who can advise on how to book in with him.

        Thanks again for choosing Omni!

        Warmest wishes,

        Daily calm supplement

        I have used these for over a year for my elderly doggie. I have certainly noticed a difference around fireworks and loud bangs, would recommend giving them a go
