The marvel and mystery of a dog such as Izzy is wonderful to experience. How do dogs like Izzy know? Also, I met a wonderful volunteer with her doggie, who visited my dad after brain surgery. The dog brought a llighter feeling into the hospital room. And the volunteer was wonderful herself. I wish my uncle, who recently died 6 weeks after a massive stroke, could have been visited by a therapy dog. He so loved his little Ipo. A dog would have provided some comfort. You and your dog Izzy are a blessing.
