Well they are too blurry to tell what's going on.

Either way as soon as the vets are open and the roads clear, I'd be high tailing it to the vet.

In the meantime, contact the seller and let them know you've got a problem.

Get some non-painkiller Polysporin (I believe that's the one if a blue tube). Wash the area to get any of the gross looking stuff off and apply the Poly every day
