If your dog is bored and looking for attention, he might try to do something naughtier that will grab your attention. Additionally, if you are not petting them enough or spending less time with them, they will crave your attention, resulting in such activities.

According to some studies, licking is one of several behaviors dogs exhibit when seeking attention from their owners. It likes the same things as other behaviors like scratching, chewing, barking, and eating.

The best thing you can do is to spend some quality time with your dog regularly before the situation worsens so that they won’t have to do such things to gain your attention.


2. Familiar Scent

If you are a dog parent, you must be very well aware of the fact that your dog’s nose is the best smell detector in your house. So, when they sniff your undies, they find it familiar as it reminds them of you, and that’s why certain times they lick it.

Anxiety issues like separation anxiety are common in dogs when you are absent for a long time. Your laundry can provide dogs with relief from anxiety. As a result, your dog chews or licks your clothes, including your underwear.
