Get fit: Zac is a strong dog who loves to get exercise in the park. | SEITARO MATSUO As anyone can tell when they first meet him, Zac is a very good-looking dog. He’s 6 years old and weighs in at over 20 kilograms. Strong and excitable, Zac was likely a poor match for his elderly owner, but when that owner had to be institutionalized due to severe senility, Zac was sent to relatives and eventually to ARK. The barrage of changes and unfamiliarity with other dogs and cats took their toll on Zac. He had loved getting attention and being pampered, and these two things are not readily available in a shelter environment. However, he has been given a lot of help learning to trust and like people.
