They May Be Showing Affection

Your Dog Might Be Nervous
Sometimes, dogs will lick their humans’ hands when they are feeling nervous or stressed. This may be because they are seeking comfort from you. If your dog is licking your hand and also has other signs of anxiety, such as Panting or shaking, it is best to consult your veterinarian.

What To Do When My Dog Licks My Hand

Some dogs develop a habit of licking their owner’s hands as a sign of affection. While this may be seen as cute by some, others may find it bothersome or even unhygienic. If you fall into the latter category and are looking for ways to stop your dog from licking your hands, there are a few things you can try.
Provide An Alternative
One method is to provide your dog with an alternative to licking your hands, such as a chew toy or bone. If you catch him in the act of licking your hand, offer him the toy instead and praise him when he takes it. You can also try teaching your dog the “leave it” command, which will come in handy in many other situations as well.
Discourage Licking With Aversives
If your dog is persistent in licking your hands despite your efforts to redirect him, you may need to resort to using aversive techniques. This could involve spraying your hands with bitter apple spray or lemon juice, giving him a short time-out in his crate, or even saying “ouch” in a loud voice whenever he licks you. The key is to be consistent with whatever method you choose, and only use it when your dog is actually licking your hand – not just when he’s close to you or trying to show affection in other ways.
Try To Understand The Behavior
Before taking any drastic measures to stop your dog from licking your hands, it’s important to try to understand why he’s doing it in the first place. If he’s licking your hands more than usual, there could be an underlying medical condition causing him to do so. Dogs will sometimes lick their owner’s hands as a way of self-soothing when they’re feeling anxious or stressed. If you think this may be the case, talk to your veterinarian or a certified animal behaviorist to get some guidance on how to best help your dog.
