Really, Dora´s fangs are seen when she smiles wide to you, or when she is ready to use them in your...let´s say leg XD If someday i draw Dora ready to bite, you will see that are LOT BIGGER than showed here. German Shepherd are BIG dogs...

Marcos pranked Dora with small ammounts of pepper a couple times btw, knowing that she is a great tracker, but must be very carefull because actually foxes are lot better than dogs about their smell sense! so both could end sneezing a lot XD
