Your Dog May Be Dehydrated
A dehydrated dog will constantly and excessively lick its lips as a way of combating dryness in its mouth or tongue.
Frequent licking in this case is a dog’s way of trying to stimulate its salivary gland, and it can also be a signal to you that a refreshing drink for your dog is long overdue.
Your Dog May Be Suffering From An Underlying Health Condition
The reason your dog is licking its lips a lot, may be due to the presence of an underlying medical condition. Common health issues indicated by a dog licking its lips more often than usual include:
Bloat refers to a condition in which a dog’s stomach fills up with gas, food or fluid, thereby resulting in an unnatural expansion of the tummy, and it can be the reason for your dog’s frequent lip licking.
In most cases, excessive lip licking in dogs caused by bloat is usually accompanied by yawning, vomiting and drooling.
Obsessive Compulsive Disorder
Dogs, just like humans, can suffer from obsessive compulsive disorder (OCD). And one of the indicators that your pooch may be suffering from OCD is a tendency to lick its lips more frequently.
OCD in dogs may occur as a result of an illness or stress. And apart from excessive lip licking, the Obsessive Compulsive Disorder in dogs is also characterised by behaviors such as tail chasing, self-injury, pacing or circling and excessive chewing of an object.
Excessive lip licking in your dog can be an indicator that your pooch is suffering from a disease or infection of the mouth or teeth.
Common oral infections and diseases responsible for excessive lip licking in dogs include tooth abscesses, gingivitis, and a fractured or loose tooth. Additionally, the presence of a foreign object in your dog’s throat can result in frequent lip licking.
Partial canine seizures affect only a portion of the doggie’s brain, and may be the reason your dog has suddenly taken to licking its lips more frequently.
Lip licking in this situation is typically accompanied by fly biting motions and unusual behavior. And a pooch exhibiting these symptoms should be taken to see a vet as soon as possible.
