The difference between veterinary Iver and human Iver is the dosage and vets do not give chihuahuas the same dose as they give to Percherons.
“vets do not give chihuahuas the same dose as they give to Percherons”
And your point is?
they give them the same dose based on weight- it goes by weight- so much per lb- you have to figure out how much the chihuahua would need based on the dose per pound-
