Pet medications also come in different forms, starting from pills and powders to liquid creams. The form depends on the particular animal type the medicine is made for as not all of them are suitable for all animals. Pet medications usually have less medical substances in them expect if they are designed for larger animals, like cow, horses and so. In those cases the dose of the medicine is many times larger as otherwise there will be no effect on the animal at all as their body mass is just so large.
