hi I got my 1&1/2 year old lab/shepherd mix female from humane society
for 2 monthes now. She's very obedient and good when she's indoor, she
can retrieve, sit, stay, search and she's housebroken.

BUT! when she got outside of the house, she's wild. She will get
completely distracted by the surrounding: pull on leash, chase
squirrel/bird, no heeling, so i can pretty much forget letting her
off-leash or do "fetch"(she would ignore the ball). I tried choke
chain but still the same. When i take it off she will run wild again.

ppl said it's b/c she's still young and she would be ok after passing
2 years old mark. But i see an extremely obedient 6 month old german
shepherd can go unleashed in the park no problem. Wonder how to do
that?

I do let her out a lot, twice a day walking around the community and
also the park, and i do bike her a lot and run her till tired. But i
can't let her off-leashed running alongside and do fetching, which is
my goal for her.

any idea?
