love this dog, he's sweet, smart, everything. very affectionate. good w/people, kids, other dogs. have to return to work, sharing house w/elderly aunt who is not going to help; busy social life. i'm concerned about dog's emotional well-being as he was neglected & hurt. adjusted well first month, now acts more silly puppy & strong (better weight now) but listens to instructions. he is very attached, & I want him to feel secure & calm. i'm an older, experienced dog owner; do well w/instructions. I'm patient & calm. any advice?
