Animal Reiki is the offering of Reiki to animals but it involves more than just applying human Reiki knowledge and skills. Animals do not communicate with us in the same as we converse with one another. They are often not truly understood and similarly they do nor always understand our communication or actions. However animals are inherently more 'aware of and' understanding of energy. They have used it historically to determine if strangers are friend or foe and many naturally appear to be very accepting of this calm energy.

As with humans, Reiki may benefit animals with physical, mental or emotional issues and consequently this holistic complementary therapy may also be of help for animals with behavioral problems that have an emotional basis of influence. Many Reiki practitioners love animals and offer Reiki to them. Some offer it just to their own animals and those of friends and family where they know the animal. A number offer reiki free of charge to residents in animal rescue and sanctuaries and others work professionally on a paid basis with animals.

Animals suffer from physical illness and health conditions, At times, they sustain injuries or may require surgery. Aches and pains frequently emerge as they age.
