An update from OtterCam

The dog otter has been in the wars.  Compared with the week before he has several new scars on his back and sides and I think both his ears have been damaged.  He must have been fighting, possibly with another dog otter but perhaps more likely with the resident female.  If so, he came off worse as she has no signs of injury (see below).  

One one night last week the dog otter went north past all five cameras.  You can see some of the damage on this video as well.

He was followed 30 minutes later by the mother and two cubs.

The video shows they were in a great hurry in the slippery culvert.  Here are the tracks from the next morning.

The videos give the opportunity to compare the sizes of the dog, the female and the cubs.  I think one cub is larger than the other so they may be male and female.  We know from a previous video that at least one is male.
