New clients - It's best to be seen for 4 sessions, if possible.
Serious or chronic conditions - One or more per week.
Small problems - Once a week until it resolves
Surgery - Once a day for 3-5 days after surgery and then once a day for about a week after surgery.
Dying animals - One or more shortened treatments per day
Ultimately the choice is up to you. These are just suggestions, based on knowledge of Animal Reiki.
