Thanks Bud, yeah aside from the occasional "back off kid!" growl from the boxer (she's 7) they're adjusting to each other fine. Poor pup is on the scrawny side though, and judging by how wiped out she was after a short walk today I don't think she's had good regular exercise.
That'll all change, she'll be my running buddy before long!
yeah the older dog will set the youngster straight
as long as it's not aggression (it doesn't sound like it is) it's a good thing
pack mentality, respect to the elders, teaching the younster
on the other note
I've seen it, that being in a shelter (or strange house) for a time
will do that too
they sort of shut down, don't exercise/play, some won't/don't eat,
maybe it's they miss their humans, get bummed out, whatever
some are scared, it's loud/noisy/lil' to no sleep or too much
being shut down/withdrawn etc.
I've experienced a lot of that with fosters & rescues
but;
they are remarkable
'how fast they recover'
a lil' love, good diet, good surroundings & fun (what we call exercise),
chasing a ball/stick/frisbee, just running or swimming (working for birds)
sometimes these dogs need a task/job, that's what they are bread for
they will come back relatively quick
good luck, you're a good man
