Ingredients: valerian, vetivert, basil sweet and sage

Pet remedy products offer a natural stress relief treatment type catered to, and designed for, our family dogs. With a main ingredient of calming valerian, that will settle anxious and nervous feelings, Pet Remedy has provided a kind solution for the worried pet. The remedy is non-sedating anxiety relief.

Stress in our dogs seems to be on the rise. There are many reasons for canine stress and some that we may not even recognise. With an acute sense of hearing and smell dogs can easily become worried by things that we see as areas of everyday life.

Signs of stress can vary and some may not even be obvious but your dog will try to calm himself when he feels worried. The attempts of self-calming displayed by a stressed dog will manifest in the following ways;

  • Licking lips
  • Yawning
  • Trying to hide
  • Self-harm by chewing or biting
  • Barking, whining or howling
  • Jumping up persistently
  • Urination or defecation

There are many reasons that your dog can become stressed. Change in circumstances, a new pet to the home, travelling, fireworks and separation anxiety can all cause worry in your dog’s mind. Older dogs may become stressed in some circumstances despite being fine with them up until old age.

A severely stressed dog will cause you, as the owner that loves him, concern. You will want to help him and with Pet Remedy you can.
