I actually learnt about these by checking out the Face Book page of Radio SAW -the German radio station I listen to while working.
The first of a "wolf" walking toward the photographer near Schartau bei Burg looks like an Alaskan Malmute to me.
The second the photo, taken at Krina in Kreis Anhalt-Bitterfeld is not great and could be a manged fox or, possibly, a Saarloos wolfdog?
The Wolf photo
And a Saarloos Wolfdog
Checking with the UK Wolf Conservation Trust to see if they agree (they see wolves on a daily basis)
And the response from the UK Wolf Conservation Trust is:
" Hi Terry, The bottom picture is a wolf. The Top picture is quite poor quality & more likely to be a malumute. Thank you for sharing"
So, Krina in Kreis Anhalt-Bitterfeld has a wolf. Just do NOT panic and go hunting it. Leave it alone.
