The subject of fear (and working with shy critters) is near and dear to my heart. Two of us behavior lasses have shy/fearful dogs in our homes and continue to work them on a daily basis. Working with these dogs is a labor of love, but it's well worth the kisses and tail wags at the end of the day.
Sibley (Lindsey's dog) is pictured below- happily hanging out in the truck as others are working!
We both frequent the Shy K-9's Yahoo Group: http://pets.groups.yahoo.com/group/shy-k9s/
and enjoy the resources of one of the members at http://www.fearfuldogs.com/. Check them out if you have a shy dog.
If you are interested in fostering (shy critters or medical need critters), please contact Erika at ekleoni@arf.net.
