Our new neighbors: 4 young Foxes

Frida (you will only hear her barking here) and I were just walking down our road to suddenly encounter new neighbors...3 young foxes. Frida was extremely curious but then ran away when the 3 little fox siblings seemed to become more and more brave and wanted to meet her too....Later in the evening we saw a 4th young sibling. Hopefully their mother is fine! Do very young foxes every play with dogs?
