My little poodle gets very anxious in the car and at home is easily triggered by pigeons in the garden and various comings and goings outsid our gate. I have used the Omega 3 oil as well as the superchews and these both have made an amazing difference to his behaviour. He has calmed right down and is a much happier dog as a result and far less stressed and I don’t have to suffer his constant barking. Win - win!
