My family visited an 11-month old female lab who's owner is looking to
find a new home for.

She was extremely high energy - not sure if "hyper" is the correct
word - but of course she's 11 months old, so it wasn't exactly
shocking. But we also noticed a couple things that concerned us. The
biggest was a tendency to jump up on people (like my daughters) when
excited. Her owner indicated that her husband had tended to play
pretty aggressively with her, which may explain that habit. Initially
upon meeting me she also shied away a bit, something I'm not really
accustomed to seeing in labs (though didn't seem to do the same with
my daughters - a male thing, her owner said). She hasn't had a lot of
training. Really pulled hard on a leash.

I guess my questions a
- How hard will it be to train (or re-train) a dog at 11 months to
correct the jumping? I havent trained a dog in a many years, and I'm
concerned that it could be a challenge to undo some of the habits
she's picked up.

- THere are a lot of labs out there, since it's such a popular breed -
is it unreasonable to expect an 11-month old not to be tearing around
a yard for 20 minutes non-stop? Trying to determine if she is "hyper"
or I just havent been around a young dog in a long time! I also know
that labs have become so popular that there may be some tendencies
that have cropped up to to over-breeding.

Thanks,
