two very sweet chocolate labs in our house now. mollie is about 20 months old and very much in her rambunctious teenager phase -- she needs much exercise or will find fun things to do in order to attract our attention. she will chase tennis ball for hours without stopping. chessie is somewhere in the 10-13 year old range -- she's a rescue and the vet estimated her age at 5-8 when we adopted her. her hips are starting to give out, and she's beginning to exhibit early signs of congestive heart failure.
