I really hope that Rob has changed his mind, b/c I know that you love Rob and Max with all your heart. And I can only 'know' Rob thru what you are saying, but noone would make me chose b/n them and my dog or cat. I would chose my critters hands down.
And the comment about just waiting until his allergies cleared up or until Max passes is just plain heartless.
I mean no offense and I do wish you the best of luck.
