Licking your feet will not kill your dog but on some occasions, it may cause an upset stomach. It also won’t get ill for as long as you did not walk barefooted and stepped on something (e.g. grass fertilizers, herbicide and pesticide granules) hazardous to its health.
Another thing that we want to emphasize is that you should discourage your dog from licking your feet and legs right after you shower. Depending on how much you applied, the residue from soap, body oil, or lotion may cause mild forms of gastrointestinal upset.
Actually, the probability is higher for you to get sick than your dog as a result of licking your feet and other body parts, more so if you have an open wound. Here are the reasons why.
It is true that a dog’s saliva contains histatins, a substance that has antibacterial and antimicrobial properties. But, let us remind you that a dog’s saliva also has a plethora of bacteria that can infect an open wound.
Some of the bacteria present in a dog’s saliva are zoonotic, meaning the bacteria can be passed on to you that may cause septicemia.
Plus, you do not closely monitor your fido 24/7, so you have no idea where that mouth has been. Dogs will devour just about anything, they lick other dog’s butts, some even eat their own poops. Your fido’s body is equipped to handle this kind of lifestyle but you are not.
The bottom line is that you and not your dog can get sick if you allow your dog to lick your feet all the time.
Apart from bacteria, your fido is also a carrier of parasites. Hookworms, Giardia, and Cryptosporidium can cause you to suffer from intestinal disorders. Plus, if you allow your dog to excessively lick your feet, there’s a probability that parasites can be passed on to you in the form of a skin disease like ringworms.
