My 185 lb miniature horse just did a 5 day horse paste trial. One click a day for 5 days. (Not one click but one 250lb mark)
It was feeling fine before I started the trial, just wanted to see what effect if any.
I can attest that my horse had no adverse reactions and appears to feel no difference from day one to day 5.
I'm not sure why everyone is so concerned about a human drug being administered to a horse. I cant tell you the number of times our dog has had human drugs prescribed for them from anything form allergies to COPD to heart medication.
Stop listening to mainstream media and just take the human drug in horse form. Its that simple, people.
HeartGuard, the dog parasite drug, has Ivermectin in it as a primary ingredient. It was prescribed to humans well before then. Stop being so stupid. People are actually taking that to cure cancerous tumors when their doctor won't give them sane drugs.
It is a human prescribed drug that also has animal applications. Get over it.
