My dog has a spot above his eye

My 8 1/2 month old chocolate lab has a spot above his eye and on the back of his two front legs. The spots on the back of his legs seem to be from rubbing on the cement when he is in the down position (they feel callased). But I can not figure out the spot above his eye. He does not scratch it, it doesn't look red, just a little callased ( I hope I spelled that right). What might it be...should I take him to the vet or is this normal. He has had the spot above his eye for a while, and the last time that we took him to the vet she didn't say anything. Any ideas.

Could be a wart - have your vet look at it next time you are there

Next time you are at the vet, get them to check it out. Good luck and keep us updated :)
