Thanks middle. There seems to be no grudges hell - whew! We know Neb isn't good about food and other dogs (a friend's dog attacked him while we were camping when he sniffed an empty meat container, is why I think) and have fairly effectively managed it. Except for yesterday. The Case of the Mysterious Piece of Kibble!
Rosa, as dog and animal lovers in general, I think we all know someone who struggled with losing their beloved dog. My husband has a friend who is going through this now. He's a single guy and the dog accompanied him everywhere, he was his world. He calls my husband and tells him how utterly depressed he is and the dog has been gone over 2 years now. So I suggested he foster a dog. That way he would have companionship and not have to get attached if he didn't want or if things worked out he would have a new best friend.
As for acts of kindness I agree giving Bob some respite and helping with his wife would be ideal if he's comfortable with it. Do you know who helped take care of her when he was in the hospital with pneumonia? In the meantime, you could make a scrapbook for him with pictures and memories of Mini that he has shared with you. That way he could open it and look at her pictures as well as have a permanent keepsake.
