Takes a while to work

It took over a week before I saw a noticeable change in my dog's behaviour. You need to be patient with the product

Good for noise sensitivity

My dog is terrified of loud noises but these capsules help to lower his panic response. Worth the money for his comfort

Excellent for travel

I give my dog one before long car journeys and he is much calmer and more relaxed. No drowsy side effects which is great

Good for medium dog anxiety

Worked for Firework noises

by Judy -

Have just used these capsules for 5 days for my Border Terrier around bonfire night and have been impressed with the effect. Instead of running around the house panic stricken with the fireworks noises he remained calm, he was alert listening but not petrified/ panting/ staring eyes/ stressed as in previous years.
