Keep going! Slow progress is great progress.
This gorgeous lady named Hippo was over stimulated all the time, over aroused, barking, jumping, stealing food off the counter, lunging at dogs on walks, and she never ever ever laid down to take a nap. Over the course of 3 months with mental stimulation, increased enrichment, learning how to have impulse control, structure, learning basic cues (name, sit, down, leave it, come, stay/release, touch, heel, settle), and lots and lots and lots of repetitions while meeting her where she was at with her training….. she is now a happy go lucky pup who gets to go to parks, restaurants, runs off leash at the beach, and has other human and dog friends!
