ISO of dog trainer/behaviorist for my 11 year-old Golden in the Columbia, MD area. My very friendly Golden barks and pulls at every dog (with her tail wagging -no growling) in the neighborhood while on leash walking. Not sure I trust her anymore to meet/greet other dogs in the area. She's as sweet as can be and will meet other dogs easily when we are not walking in our neighborhood - like around the lake. I know she's 11 but I've tried everything and the behavior returns. Would like to have a behaviorist come to my house and walk with me. Any recommendations? She's 11 but has the strength of a teenager!
