Mariana is the smartest dog we met. Probably the fact that she spend 8-9 years on the street made her this way. Since we know her she is resourceful. All the time we saw her on the street with food and at a certain hour when a lady on the street was feeding other dogs too. She learned from somebody how to give to other the paw and that made the workers that were on the street to like her. Now she is in the shelter. Even If she is loved and liked by everyone she needs something. She needs a family, a warm house and a quiet, carefree pension. She can be adopted anytime and you do not have to work with her. Even If she is not young she is playful.
