Aww, those doggies :) Must have been a truly unique experience. Btw talking about "doggie wolves", have you heard of this breed?
https://en.wikipedia.org/wiki/Czechoslovakian_Wolfdog
It´s a breed that was "created" here in my country by crossbreeding dogs and wolves. Today, these dogs only have a very small % of the wolf genes in their DNA but in appearance, they still look like wolves very much. I sometimes meet these dogs here and they are so beautiful! Maybe your sister will also be interested in this so let me tag her here :D
