Quoting Leigh Riggins:" I didnt really know where to put this lol but anyways I was holding my son and the dog had to go out ... [snip!] ... I am just frustrated she doesnt do anything for him except call him hers and sleep with him (like that is a task or something) "
It doesn't matter whose he is, someone needs to take care of him. If she wants to call him her dog, who really cares. If you want the dog to stay, I would suggest taking responsibility because it doesn't sound like she will. If you can't(understandably) maybe you should give him to someone who can.
