WW dropped the dog off with them, saying he wasn't happy with her,

Smart dog!

Still, as big a deal as she made over the dog (even amending the divorce paperwork to reflect that she wanted the dog) I can't believe she just dropped him off. Makes me think she just took him to be petty.

I don't think so. Remember, she had to go out of her way to get the dog. And you willingly agreed to let her have the dog.

I think she expected the dog to bring her comfort in her looney wayward life. But, there is no dog who can do that.

Now she's chasing OM believing he will bring her life meaning and fullfillment.

So sad.

They said he's lost weight, and seems fearful now.

Well, at least she gave him back, rather then dump him somewhere.

Will you get him now?
