Teething Phase
If your pet dog is in the puppy phase of two to eight weeks of age, their milk teeth will get replaced with the adult ones. Due to this teething phase, the dogs can rub their faces on the ground.
Here again, the puppy performs this action as a countermeasure to tackle the pain involved with the teething.
Eye Irritation
Did you change your dog’s shampoo recently? We advise you only to get gentle shampoos that are soft on their eyes.
Apart from this, there are other more severe medical conditions of ulcers in the cornea, inflammation in the outer eyes (also called Blepharitis), and eyelids.
Here too, taking your dog to the vet is completely necessary.
Dental Issues
Your buddy may be rubbing their face as a result of suffering from dental problems. You can identify this issue if your dog is eating fewer food quantities recently or chew the food only on one side.
Other signs of dental problems include the presence of blood in the saliva and bad breath. Getting this problem sorted out with the help of a medical professional can be a painful procedure, but it has to be done to avoid it from getting worse.
Attraction Towards The Scent
The scents which humans find attractive may not be so for dogs and vice versa. Dogs can be fans of the smell of many strange items like grass, poop, or insects. Therefore, they rub their faces and bodies to get that smell attached to them.
When you apply the same logic, you can understand why your dog runs off towards the grass or the carpet to get rid of the smell of shampoos or soaps right after their bath.
Breeds With Wrinkles
Dog breeds with wrinkles such as Pugs or Bulldogs can cause them to rub their faces due to their physical structure. The reason is that the skin between the wrinkles can easily collect dust, bacteria, food, dirt, etc. that can cause irritation.
In order to dislodge this uneasiness, the dogs will resort to rubbing their faces on surfaces with friction.
Apart from all the above-listed reasons, your dog may be rubbing their body or face on random surfaces just because they enjoy doing it. Just like humans, dogs can also resort to a few irrational behaviors for the sake of it.
