Your vet said to stop the antibiotic and you did....if the symptoms are worse or not improving, I would simply call the vet.
Not exactly sure what dosing has to do with this; but let me just say that vets can do math and can calculate dosages for all size animals. Vets, just like human doctors, are educated in pharmacology. Sure, mistakes can always happen; but to assume that vets cannot do math is insulting imho. |
