I admire this lady from your description of her.
It is perhaps too bad that more dog trainers do not open schools for parent training as well as owner training, is it not?
She was a dear. We had daughters the same age, who are now 20 or so, and she had an older daughter from her first marriage who would “mother’s help” for me sometimes. For example, her daughter would go with me to my dance class and rock my infant while I danced.
Animal training techniques can be of use to parents, but one doesn’t want to go overboard. A human child had more individual drive than a puppy ... although puppies go their own way, too, and they’re not all suited for police work.
