the answer has always been...we already have two Dogs!
So, I deiced that it was time for the kids to learn a little dog Responsibility...I stopped picking up after the dogs in the back yard for a few weeks and this last Sunday sent the kids out to pick up after their dogs....half way through the smell was getting to them and Tyeann fixed herself and brother up-take a look at their nose.
Well see if they keep up with this weekly chore and if they ask again for a puppy.
