Hi Sandra, I am so soorry you have to go through this, but if it were me, I think I would be grateful that someone was willing to assume the cost of caring for an animal that I loved and could no longer afford to care for. I don't think its cruel, you already made the hard decision to draw the line financially. You shouldn't feel guilty about that, we all have limited resources and priorities, and taking care of home and family should come first. But knowing the dog is sickly, and its probably not just this one surgery, I think you should rest easy knowing that someone is willing to take on the financial burden. What financial arrangments he makes with his office staff is really between him and them, I am sure he is giving them a break, but it's probably part of their compensation pacakge (many people get discounts where they work), so maybe that is the best situation for a dog that is likely to require further expensive care. Rest easy, knowing this hard decision gives him the best gift you can, LIFE.
