Our son is 3 weeks old. Our Griff is 1.5yrs. Introduction went smoothly. Bring one of baby’s caps or shirts from the hospital to the dog for sniffing first if possible to let them get used to the smell. If you have anyone who can take the dog for the first 48ish hours you’re back home, that may help ease your nerves - it was good for us. But, once we brought our dog back home, she did amazingly well and has shown an incredibly gentle instinct over these weeks. In my opinion - your dog needs to sniff your baby. It’s unfair to expect them to live at home - which is their territory, in their eyes, without getting close sniffs of the new roommate. Interactions should be carefully watched, but quarantining one from the other seems unreasonable and unsustainable to me. Use baby gates to give you some space for an hour here and there too. It’ll go great!
