well, i have yet to see big lab handle upland hunting in warm temps here in pa.

you are most likely right,conditioning has a lot to do with it too.
including small labs too.
when i was searching for my lab,i was told by one of top kennels here in pa. to get a small lab if i was going to upland hunt and not duck hunt..

they said big labs are better for ducks..
this preserve trains and trail tests dogs in our area..
they are well known..
