Frog might have a broken leg??

if you think your frog is in pain, you can go to petco and get some clove oil dilute it in water and humanley put it down. if you think it is minor i would go and get some anti-fungal medication and start treating now so you prevent the growth or stop and cure the growth of fungus (which will kill your frog if the injury doest). the biggest thing is dont blame yourself for the frogs death if s/he does die, it isnt suffering any more. good luck and i hope your froggie gets better.
