I agree with lab and rotwieller based on the looks. But they were together and probably siblings, so my guess is just plain ole mutt. Plain ole mut is my favorite, after I am just a mutt.

I also have a stray that I dewormed, got shots, de-flead and etc. My hat is off to you for having the heart to rescue this fine pair. If I did not have my Toby boy, I would take them off of your hands.

I hope that you find a good home for them. Good idea to show them on this forum--hope it pays off.
