I was thinking the same thing about not putting the dog to sleep. If he was adopted by someone without children he should still do fine. The way it reads, he wasn't trying to attack the baby, it was out of some misguided sense of protection or play.
As I've said, I always take the dog's side.
I'm sorry but if your child is born three weeks early, then he's not going home from the hospital right away. That gives Dad time to go buy a baby monitor. I'm not jumping to conclusions, I'm going by what I've read. It also said in the article that they knew one of their dogs was physically able to open doors. No one knows if they could have done more except the parents. I'm sure they have tremendous guilt for what happened. Who knows? Maybe they could have done everything right and it still happened.
Not to be rude, but that is just not true. 37 weeks is considered term for a healthy pregnancy. I have one friend who had her baby 6 weeks early (5lbs) and one who had her baby 4 weeks early (over 6lbs) and both went home in the usual amount of time.
