I cant even imagine having to endure the situation you have described. And, every post u add describes even more distressing info than before. I Iive in the sticks too, & certainly there is no "animal control" out here, other than livestock owners taking care of nuisance animals with guns, using the sss method if necessary. A shame that u may need to carry a firearm to walk to your mailbox, but maybe that is ultimately the best idea if no better fence solution can be found. But even if u never need to use the gun, the daily emotional stress is surely tormenting. Re using a stun gun, i realized the zapping sound would scare your dog too, so maybe not a great idea after all. Re bear/pepper spray, i think that would work better.
Just make sure the wind direction is not blowing toward u, or pepper spray could end up in Your/your dogs face. Some pepper "spray" actually comes in the form of foam, meaning it shoots further before dispersing.Spray/foam with a laser pointer helps accuracy too. However, after the recent descriptive info u have added, and fact that you live in the country and CAN carry a gun, thats what I'D do if i were you. (Until the fence issue is hopefully resolved). Forget stun guns, bear spray, baseball bats, or any other nonlethal weapon. If u dont own a gun,a problem may be that AMMO is currently so hard to find. I have been seeing more 9mm ammo in gun stores lately than any other type, but that may vary by state/region for all i know. Again, so very very sorry u r dealing with this. Even tho i would be carrying a hand gun whenever in proximity to the dangerous dog(s), situation would still Totally ruin my quiet peaceful country living. And knowing there are toddlers neighbors to those dogs is very scary too. Even if the kids are taught and Heed instructions to stay far away, the kids may end up having instilled within them a lifelong fear of dogs. Which would be such a shame, since most dogs are awesome! Keep us updated. Am hoping u soon find a FENCE solution to restore your peace of mind.
