@Motala - That is good that you talked to Jan and glad to hear that she had not been spayed. I still think that your Vet and you should connect with Dr. Gonto about your girl's blood work and blood gas results and if he has any thoughts about it.
Yes. It seems crate training is super important as safety to the dog. As to B escaping, I am not too worried as at my house there is a inner court yard that has another door leading up to my front door. Usually when people ring the door bell, they ring the outside bell. I though have to go through 2 doors, which is great especially if the dog escapes from one door, he is stopped at the other 😉 That portion I am pretty confident.
