Dogs can be viscious and i think the whole fear of them is born out of the fact they have sharp teeth and make lots of noise. They are much like you average saturday night drunk who likes to start thinking he is hard in front of his mates, gobbing off etc but when you turn the tables on him and turn up the agression, salivating as you tell him "F*** OFF YOU KUNT!!!! OR I'LL BITE YOUR FACE OFF" then you will quickly see that he suddenly has an urge to return some library books that are overdue. This doesn't always work of course . Like i said in my previous note dogs draw support in packs.
Also lets not forget, the only thing you have to have covered from a dog is its jaw. Nothing else. The limbs of a dog cannot punch, kick, accurately try and gouge your eyes out. If a dog is coming for you become agrresive towards it. If this doesn't work and it still keeps coming move from 6-9 oclock as it gets near, make sure you have its jaw covered and rip the fukcing jaw off. We are much stronger creatures don't forget that. We have more attack tools at our disposal that a dog. Although that seems to slip our minds when faced with a salivating 10 stone rotty
