Oh, Jessica, First of all, Let me say I am so sorry to hear of this terrible loss. This must be hard for you. Jessica, I guess if I were you, and I were able to take the dog and wanted it, I think I would and only for one reason. Because, right now, the family is in shock. You can take the dog and let the little boy know (on the side) that you will keep the dog for him until they are ready to take the dog back, whereas if the father finds the dog a home with a stranger, they may never see the dog again. You can help them this way. That poor man is going through a terrible time right now and he isn't thinking straight. Or, if you know him really well, you could tell him how much the dog means to the little boy, he may not have even thought of it, being so distraught over losing his wife. Again, I am so sorry to hear of your and their loss. This is a terrible thing to go through. I know.
