DO NOT let your dogs lick you. My brother-in-law got real sick a couple years ago and was in the hospital for weeks. His right leg was twice the size of his left. It was a bad infection that was spreading fast. The doctors were puzzled. They brought a team of experts and one doctor was looking at his right foot when he asked if my brother-in-law had dogs. He said yes then the doctor asked him if the dogs ever licked his feet, BINGO they discovered how he got it. It took months to get him back to normal.

PS: I have 2 dogs but don't get to involved with either.
