Activator is a handheld, spring-loaded adjusting tool that works great in young and old; large and small dogs. It is perfect for dogs who may have difficulty relaxing or need to move during the adjustment. It is very precise, gentle and effective.

Extremity adjusting involves every area outside the spine; the legs, tail, pelvis and sacrum. Dr. Irven uses both hands and activator for these areas and it can prove very effective in animals who have injuries effecting gait.
