Wow! - I just went looking, rather wistfully, for the Sep-Anx protocol that Dr Overall once posted on her website - thinking that, of course, i'd never find it...
& lo & behold, i found ALL of her clinical small-animal behavior modules!
there are 29 separate, individually-written, step-by-step programs to address specific issues.
Dr Overall is a DVM, also a Board-certified specialist in Behavior, & editor of
JVB - the Journal of Vet'y Behavior.
