Gun Dog Forum

It could definitely be simply behavioral, i have a spayed female who will still mark. Finish out the antibiotics, if she still does it, then blame it on behavior

Go with the labrador. Chessies are more aggresive (at least the ones i've met.) I find female dogs easier to work with, but thats your call, whatever you choose, get them fixed. I don't think color make much of a difference, but i've heard that chocolates are "quirky"
