I understand where you are coming from as far as needing to do what is best for everyone... keeping baby safe, the dh happy, and making sure your yorkie is loved all around!

I would take the advice and info given by LadyJane.

If you do decide to continue to rehome him on your own, I would not let him go to a home with no other dogs. I would look for a home that already has at least one dog, small, medium, large doesn't matter as long as your boy gets along with him/her. And get vet references, and ask how long they have owned their current dog/dogs. The longer the better.

A lot of time first time buyers end up rehoming the dog because they thought they could handle the "quirks" because the dogs cuteness was more important. But things like his excessive barking or snapping at baby will be faults and the new family could tire of his quirks easily. and soon enough he will get passed again.
