I think it was you who suggested getting a doll to help Elie and Digger adjust to the baby. Well i decided to try the idea. I left them and the doll alone for 2 minutes and you wouldnt believe what they did. I wish i had a camera so i could take pictures and show them to you. I came back and Digger had the babies head in his mouth running around the living room. Elie had the body and was dragging it behind the couch. By the time i got it away from her the arms and legs were ripped off and shredded. There was stuffing everywhere. I got the head away from Digger when he tried to bury it in his kennel.
I hope they have a different reaction when the real thing comes. Lol. I did take them to a friends house who has young kids. They were not very happy about it. I think it was mostly the loud noises that bothered them. I have been taking them for walks around playgrounds and stuff lately and that seems to be helping a little bit.
LOL. I think they will know the difference between a living breathing baby and a doll. It was probably just another stuffed animal to them.
Good luck. My sister's dog learned to coexist with her kids but never really liked them. She told me the only time she gave them any attention is when they had food. She was a jealous dog though. It probably depends on how jealous your dogs are of them.
I'd never leave a baby or little kid alone with any dog anyway since they don't know how to pet the dog properly and the dog may think it has to defend itself.
I think you are doing great trying to get them used to kids. Maybe it will keep them from being startled easily if they get used to all the noise kids make.
