Behavioral reasons are the most common reasons as compared to the medical reasons for excessive licking. Most of the time, and with most dogs, it is not a sign of serious illness; dogs may lick more to groom themselves. Many vets and pet experience pet parents agree that owners taste salty, which is why dogs love to feel them. The salty taste of the owner’s skin is a sign of affection for dogs, and it’s their way to express it when owners do not give a shut-up call the licking becomes a habit in dogs.
While on the other side, when there is no activity for a more extended period, these social animals become bored. To overcome their boredom, they start licking excessively and even on shut up calls, they do not stop. It can be calming and soothing, just like a massage for a human being. It’s relaxing for them, and when dogs licking excessively suddenly, that means they need some comfort.
If the sudden licking becomes excessive, that might become a cause of hot spots, hair loss, irritation. Do not punish your dogs in such conditions because this activity is attached to the behavior, and you need to deal with it technically. Provide them alternatives to stay busy, like toys that can keep them occupied.
Trainers and vets agreed on a point that positive reinforcement training also helps to curb the excessive licking. You can reward your dog for stopping their licking in such training, especially when you say leave it, and he honors your command.
It is easy to deal with the behavioral issue of your dog licking excessively suddenly. With just a little effort and training, you can teach your dog to control it.
