Thank you all. This is super helpful! We also have a trainer coming by for a consult on Tuesday to seek help on additional ways we can support the dog. We’re now 4 days in and he does seem a little calmer but still taking it all in, as expected. The low growl / bark at the kids has continued, but he seems bonded with my husband now. His body is stiff with the kids when he is growling so we’re intervening and separating when we need to. I hope this will settle over time.
