Hello Logan! What makes you think toad is sick? Is it eating? Has toad's behavior changed recently? Also, please read this care article (Frog Forum - Toad Basics - Keeping ground-dwelling Toads. A care sheet for Bufo, Anaxyrus, Spea, Scaphiopus, Ollotis, Alytes, Pelobates) and see if something is amiss in your enclosure, good luck !
