K.S.
I can't speak of routines after but so it is not a shock I will share something we did. The night my husband went home to sleep from the hospital he took with him a blanket, t-shirt and soiled diaper from my son for our two weimariners to smell. He threw out the diaper shortly after. Our dogs sleep with us so hubby brought the blanket and shirt to bed and placed it on our pillows. That position shows high honor in a dogs pecking order. Lastly we brought the pups out of the house to greet our new family (pack) member attempting to be on neutral territory and then all walk in together. We have had no issues.
Something I also made a point to do for as long as we have had them is pull on their tails, ears, stick my hand in their mouth. I have also spent time ensuring we can approach and stick out hands in their food bowls while they are eating. My dogs have to wait for permission to commence eating when their food is put down. I always make it clear it is my food they are allowed to eat. Very important since they are both rescues and we have young children in the family before I had my own.
