We have 4 dogs. No, we aren't crazy...... well, yes, we are, but are lucky enough to have a good-sized house on 3 acres.
OK. So doing the math here:
that's 1.33 dogs per acre
or 1 dog per 32,670 square feet
or 1 dog per 4,704,480 square inches
Now if each dog leaves a pile of doggy doo doo approximatly 12.566 square inches (3 Radius Squared x Pi) twice a day to the tune of 25.132 square inches (100.531 square inches total dog deposits)... uhhh! I forgot where I was going with this, but my point is you have room for another pooch.

Qualiity. Not Quantity!
