        Settling a rescue Spaniel

        We adopted a cocker spaniel who was not quite 2.

        We are her 4th home.

        She was scared of everything people , other dogs etc.

        We started her on the daily calm supplement and slowly she has much improved.

        It took 4 months to see a real difference but so worthwhile now. Love that you can choose when to order too.

        Great calming treat

        These really work! My rescue springer has always been nervous, due to a bad start in life. There really was a difference when I started giving her the calming supplement. I have started giving them to my other rescue Sprocker in the run up to bonfire night. I recommend them to anyone I can….I am so pleased that they work. Thank you Omni.👏🏼🐾

        Daily calm

        I wasn’t sure these would help my cockerpoo who barks at everything. He didn’t like then for the first few days but now takes them daily. He is still barky but seems a lot more relaxed than before he had them.

        Calm treats

        It’s difficult to know if they work

        He’s now 6 years old and has daily walks and runs on his own and with other dogs

        We walk about 5 to 6 miles a day on and off lead

        So he is really much calmer

        Have helped our dog so much!

        Our dog really struggles with anxiety whenever we leave the house or have to separate from her. We've tried absolutely everything but nothing seemed to make this any better until we discovered Omni. It took around 5-6 months to notice a difference but it was absolutely worth it! She's so much calmer now and a happier pup overall. Thanks Omni!
