Dobermans (possible spoiler)

A great movie and one of the summits of Mexican horror cinema. However - one scene I have a bone to pick with as to logic & believability, and that's where the three Dobermans attack the two policemen at the castle. Certainly two professional military types armed with pistols and swords would have been able to fend off three dogs, however strong and vicious the dogs were. That being said, it's a unnervingly effective scene, pretty graphic by the standards of the time.
