Hi Carene,
The dog who is coming to vist you, does it live very far away? I ask this because it sometimes helps if he/she can first have something with your dogs smells on, an old blanket or toy of some sort. Likewise something with the visiting dogs smells on for your dogs to sniff on before the arrival could help.
But in all honesty, I don't think you will have to much trouble. I take my 'Gas-Bucket' back each year, to see his mum and sister and they are all over him.
I bet you can't wait to see one of your fledglings again.

:D
Best of Luck.
