Regina was the runt of a litter of mixed puppies our yellow lab had in 1994.  She was the last born, and we were there till the end.  She was the smartest dog we've ever seen.  She loved chocolate, she and her mother even ate over 7lb of easter chocolate because Regina figured out how to get the tins open.  She also opened doors with her mouth and to our surprise and demise, cat food cans (even though it required cutting her mouth and tongue she loved it.  She even moved with us thousands of miles.  We recently put her down because we felt it was time, she lived a bold 11, almost 12 years, and had fun doing it.  She was with me from age 11 to age 22, and I will miss her most of all.
