We have had our 16 month-old dog, Pippin, since he was 8 weeks old. He is a ~50lb, neutered, house-trained, energetic Lab/Springer Spaniel mix, and is very affectionate and eager to please. He knows basic commands and several tricks, and is very trainable. However, he has a history of unpredictable behavior around other dogs (except our own, older Lab/Boxer mix) and young children. Despite our efforts to correct this behavior, he actually bit our 4yo niece on Christmas Day. He would do well in a home with older or no children, with someone willing to continue training his high energy personality.
