        Daily Calm Supplement review

        I really hoped the supplements would make some difference but i think that its likely a discussion with a vet about some medication to lower my dogs trigger point is now on the cards. We've been using the chews for nearly a month. The chews are well packaged and my dog will eat them easily. I'm sure other dogs with slightly lower tension and anxiety will benefit as they are packed with a range of calming content.

        Definite difference

        Omni has had a definite effect on my dog and although it’s explained that it can take a little while we saw a difference in days. She is calmer … still barks when she hears something but much less, she doesn’t seem as anxious or worried about things. She is still playing, enjoying long walks and her mischievous self but much calmer and quicker to settle when she does bark. In fact she has ignored things that would usually set her off! She won’t take it as a chew but I crumbled it over her good and she has eaten it every day. 😊

        Too early to tell

        I've been giving my Dachshound your supplements for a couple of weeks now. She likes the taste but it's a little too early to see any benefits. Will order some more and see how it goes from there.

        Definite change

        Our dog is a large hound and was not a pet when we got him aged 3. His anxiety was worrying - he would be relatively calm with us, but anyone visiting the house made him uncontrollable with anxiety. He was not aggressive, didn’t attack or snap, but would howl and charge up and down the stairs and around the house ‘flacking’ his ears and shaking visibly. It took quite a few months for Omni to have a significant effect and he still hasn’t gotten used to strangers coming to the door, but his everyday behaviour is very noticeably more rational (if that’s a valid term for dog behaviour) and is much calmer. He calms quickly in the presence of female visitors but still reserves a little madness for males.
