Okay, Dave, you deserve some sort of prize. I have answered thousands of questions since starting the Gear Guy in 1997. (thats right1997. Thats pre-Cambrian in Interwebs time.) I have dealt with odd requests around tents, boots, stoves, jackets, you name it. But never...NEVER...have I been asked for advice on how to deal with fierce, rabid dogs...in Mongolia.
But I agreea twig and a snowball is hardly worthwhile protection against a pair of hungry Mongolian canines. My advice: Pretend youre in bear country. You need some kind of easily portable, easily deployed, chemical-based repellent. Something such as Counter AssaultBear Deterrent ($45) and a holster to hold it ($12). This is powerful stuffsuper-hot red pepper derivatives that can hit a target= up to 30 feet away. A shot of that in the dogs eyes, and I think you will be okay.
Of course, that implies you have access to Western retail channels. And for all I know, you do not (although you obviously have Web access). You can make home-made deterrents using common ammonia and some water. Mix them to about 1:1 and put them in any kind of squirt gun or spray bottle thats easily carried. Thats very effective, too. Just make sure your spray device doesnt create a fine mist that can blow back into your eyes. Then youll be blind AND chased by mad dogs.
Might be worthwhile to carry half a dozen dog biscuits, too. Seriously. If theyre hungry, food will throw them off the trail long enough for you to escape. I think.
Anyway, thanks for writing! You made my day.
