Are the top two photos prints of an otter? I have put an obvious dog print below for comparison. Both were a similar size, that of a medium-sized dog.
No interactions present.
I think the left-hand print is double-registered, and does not have 5 toes at all. The '5th toe' on the right hand one is from the small partially melted print just right of bottom centre. Also no webbing, though that does not always show. Dog.
In the light of your comment I've added another photo from the same set of prints.
I think that just proves it.
Yes, I thought they might be a bit big for otter. Any other comments from anyone else?
