I camp with my dogs. The bear wouldn’t have gotten even close.
The minipin would have set up the argument, the maxipin would have attacked.
Bears just hate it when little dogs latch onto their noses, and big dogs bite their haunches.
P.S. the minipin is brave beyond stupidity. She WOULD attack anything, and probably die. The maxipin is cautious and would probably live to fight another day.
I suspect the dog was what the bear was after.
