    Helping our dog through fireworks season

    We've tried the Omni Stress & Anxiety chews for our dog to help him through fireworks season and we've found they've really helped. Being vet formulated we know they're good for him and he loves the taste so happily eats it with no trouble!

    Great products - already noticing a difference

    Our dog is very anxious and reactive to people, since starting him on these supplements four weeks ago, he definitely seems calmer and is quicker to calm down if he does react to someone. Will keep going with these for a few months to see if there is anymore noticeable behaviour changes and will recommend to others

    Chilled out.

    Bought these in prep for firework season. Have introduced them gradually to see impact.

    Ruby is definitely much more relaxed and in fact 'flat oot' as we say in Aberdeenshire.

    Yet to see how this translates when the bangs start. But early indications are good.
