Part 3. Exercise
What it is about "Henry Dog". My daughter was 6 when we gave her Henry. Love is not the word. Obsession! A few years later my ex-wife decided he had to go. Under the guise of an "incurable" lice infection my ex-wife threw him out. Trauma followed. We bought a replacement which my daughter has safely on her closet shelf. He is thread bare. I found him online and was overwhelmed to read the reviews at Amazon.com. None had less than 5 stars. Each story told how this little guy had touched their lives. These Henry owners, both girls and boys, cherished him as if he had been a "real" dog. I guess to them, he is. Daddy had to buy his little (40 year old) daughter a new one. I got both the 14" and 3". I was on the phone when she opened the box..... Henry was home again. My granddaughter saw Henry got excited and wanted one also. She is 19 years old. This company should bottle "Henry Dog's" charisma. Thanks for keeping him alive.

Positive
