The allergic reaction was caused by his rabies shot.
So how about not jumping to conclusions? If you knew all the other risks I've taken in my life, you wouldn't be saying that I live my life in fear, believe me.
I could only extrapolate that your dog had an allergic reaction to something he ate or rolled in, and that's generally because people let their dogs run loose.
I don't know anything about you but your, "I would NEVER live alone and have horses!" post lead me to believe that you're a fearful person who never sees the glass as half full, only as half empty.
Responsibility to your animals does not mean you're tied to them with an unbreakable, permanent umbilicus. If you think the BO/BM never leaves or doesn't have a life outside of their clients' horses, you're sadly mistaken.
My horses and other animals are taken care of very well. Just because I'm not paying someone else to do it doesn't mean I'm not being responsible.
It also doesn't mean I'm a neglectful owner if I'm not there 24/7/365, watching over them and having heart palpitations every time they take a misstep.
They're animals, not delicate invalids who need to be bubble wrapped and monitored constantly.
