Wow...I took a needle from a 5 way when a yearling freaked during vaccinations...so far I have been Eastern/Western/Tetnus/EHV1&4 free for several months!
Well I'm just going to add that Ivermectin(or any off brand of Ivermectin) tastes like crap and yea it tingles too...so I should be worm free as well...lol
