  • Product Information

  • Like humans, dogs can experience anxiety now and then. Pets can feel stressed by changes to their routine and environment, or storms, fireworks, and travel. We’ve expertly formulated Happi-Tails to support your pet’s wellbeing and promote a sense of calm in times of need.

    Happi-Tails contain safe but relevant levels of the B vitamins, as well as magnesium, to support the normal function of the nervous system. The inclusion of passionflower, lemon balm, and L-tryptophan, meanwhile, are well-known for their calming properties.

    Pets love the taste of our dog calming tablets. Coated in a delicious beef and liver flavour, simply add whole or crumble into food and mix well.

    Happi-Tails is made in UK factories working to Good Manufacturing Practice (GMP) to meet our strict quality standards.

    Still unsure if our dog calming tablets are the right choice? Don’t worry. Our team of expert Nutrition Advisors is here to help.
