I have been giving my 200 lb horse about 1/2 inch of horse paste every friday for about 5 weeks to make sure the other horses in my stable can take it if they get any viruses from people who create viruses for fun.
Was planning on going to get bloodwork at yearly, but last night had to go to the ER for other reasons and they did full blood / urine / imaging and all is well, liver / kidney / etc.
Just an FYI.
"Their" scare tactic is saying it causes organ damage
If it did, there would be carefully worded warnings in the patient information insert for Stromectol (human ivermectin pills).
