Charlie is very great at letting you know when someone knocks at your door, very loving, playful. He can be stubborn, but is easily distracted. My mom is elderly and she loves him more than herself, however for some reason over the last couple years (since she has moved here from Wisconsin)he has become 'nippy' towards her, especially at night or if he is sleeping. Mom would like to find a new home for him, as he seems to not want to be around her and he has bitten her. She does not want him put down, and perhaps it is just his environment with her.
