Mac's was born in April '09 and was extra small due to a heart murmur. That healed and he now weighs 22 lbs. He has a gentle disposition -- seems to love people of all ages and dogs of all sizes. He never barked and tended to be a couch potato --or did until Miss Marci arrived .This little lady only weighs 11 lbs now but has energy to burn!! They race around our yard -- They are taken for a walk of about 4 kilometers most days and then arrive home to race around the house!! When they play the volume of their exchanges of 'conversation' are amazing -- such a variety of sound and pitch! Mac's has found his voice but Marci has the last word. She has added a real spark to all our lives and we love her. Thank you !!!
