    Based on short term use

    The dog loves it certainly. I feel he needs to be on it for a longer period of time to be able to give a proper review, but I can say that he seems to be a much happier dog than he was previously. Time will tell if this is a lasting change or not!

    My puppy is a romanian rescue dog.. a very anxious and reactive dog.

    He has been taking Omni Rescue Stress & Anxiety for about 6 weeks now. I can honestly say there is a marked improvement in him. He is more content; happy; easier to train and loves going for his walks now. Highly recommend Omni Rescue

Your Questions

My dog has allergies; are these suitable?

Omni Rescue Soft Chews are free from common dog allergens, including animal protein, dairy products, soya, and grain, so they are suitable for sensitive dogs.

Can I mix and match these supplements?

It is safe to mix and match the supplement variants as they target different functional health benefits and have distinct active ingredients.   If in doubt, our vet team are at hand to advise on individual cases; please email us at

How are these different to other products on the market?

Omni is leading a pet supplement revolution by saying goodbye to pills, powders and other high-calorie alternatives, instead focusing on a potent 1-a-day soft chew that your dog will love and that uses cruelty-free, evidence-based ingredients.

What’s the most cost-effective way to purchase? 

Subscribing automatically unlocks a 20% discount on first purchase followed by an ongoing 10% discount on subsequent orders. You’ll also get 6 loyalty points for each 1£ spent (rather than 1 point) which can be used for further discounts and special offers.

Do these actually work? What evidence is there?

We certainly hope so - our vet team formulated each supplement variant to choose ingredients with an evidence base for their efficacy. Where this was lacking, ingredients were selected based on sound scientific principles and reasoning to support their use. The benefits of our and other pet supplement lines are constantly being studied and reviewed, and we continue to evaluate ingredient inclusions over time based on these findings.

Can these be given with Omni’s functional treats?

Due to extremely low inclusion levels of ‘active’ ingredients in our functional treat range, giving both products alongside one another is not contraindicated.

How long before I start to see the benefits?

We generally recommend administering a daily soft chew for a minimum of 3 to 4 months to see the full benefits, though you might notice subtle improvements before this point. If you have questions or concerns regarding this, please get in touch with our vet team by email at 

If I subscribe, is it easy to pause, amend or cancel?

Your subscription is fully flexible, and you are always in control. You can pause, amend, or cancel anytime by logging onto your account page in our members’ areas via the main homepage. Our customer excellence team are also available 7 days a week to make any changes for you.
