Every once in awhile Ruff seems to know when his Mom needs some special attention. Like last night, for no reason, Ruff went up to Jackie and she leaned over and gave him a big hug. Ruff responded by giving her a big kiss. They both seemed to enjoy it. My wife has had Alzheimer's for some 4 years now and both Ruff and Axl seem very attentive towards her. The two boys have been a big help to me keeping her company.
