YIKES, now I know why my dog has had several sneezing fits immediately after running thru the type of stuff described in the article - I always assumed he was allergic to a certain type of grass or weed! I have looked every time up his nose, in his eyes, ect. & couldn't find a thing...I will be paying much closer attention next time.
This is the first dog out of four I have ever had this problem with - and it has been repeatedly. I wonder if there is something already lodged deep inside or if he on keeps getting into these type of awns (primarily during my backyard training in the Denver foothills). I may have just found the answer to a long-puzzling question of what keeps making my dog sneeze violently & pawing at his eyes from time to time. This has never happened out in the rooster fields or a duck blind, only in my heavily weeded mountain backyard.
