Thanks for the kind words, prospectmom, and the good article, HE--I appreciate you finding that for me.
Maureen--any further "telling" to anyone would result in resentment, I would LOVE to flat out publicly humiliate these people but I know it would not help and might hurt the dog.
Believe me, I have tried to figure many many angles to "get to" them, but glad I have not (yet) acted on any. My righteous indignation flares up regularly, though!
azaware--yes, there is a fence but dog can tunnel under. They have said for 7 years (age of dog) they will secure the yard but never have. Buy them a doghouse? They have new home, adorable clothes on toddlers, recent vacation, new outdoor barbecue. As for buying the dog--if I wanted a dog, I would have a dog, believe me! I've felt guilty, but am trying to remember that whatever happens to the dog is 100% result of owner's behavior, not mine! I do know there are 2 sides to every story--because I realized this might come to public/legal attention, I have carefully kept non-exaggerated records. For what it's worth, I've known many many dogs belonging to many many people--have never had any cause to think twice about their welfare.
Animal neglect is not just mean, it's illegal--and it's illegal BECAUSE it's mean.
In this case it's just not mean enough. Truly lousy situation.
