I can see it from both sides.
First off, the dog was obviously re-placed in a decent home, which should be the firstmost/foremost thing here.
BUT - the fact remains that dear "Ellen" didn't adhere to the rules of the adoption, which were clearly spelled out to her at the time, but which she chose to ignore. And then when she was called on it, all her bringing in the media & sobbing uncontrollably on camera about the situation was rather stomach-turning, & wouldn't have meant squat to anyone if she hadn't been a celebrity.
If she had half a brain in her little celebrity head, she could have called the adoption folks ahead of time, explained the situation, have them check out the new people/home ahead of time, & avoid all this hoopla. Instead she figured she was above the rules.
Don't get me wrong - I think the adoption folks didn't exactly handle this well either, but they also probably did not want it to look like they'll just bend the rules for anyone, & I don't blame them.
