Dogs develop mouth skin because the mouth skin is excessively moist, causing the mouth skin to swell and thicken. This usually occurs when there are too many trichomonas or bacterial infections in the dog's mouth. This situation usually occurs when the dog's drinking water contains a large amount of bacteria for a long time or there is food residue in the mouth. Long muzzles can also be caused by genetics in dogs, especially in some breeds such as Labradors and Afghan Hounds.
In these breeds, it is normal for the mouth skin to be thicker and longer, but if you find that the mouth skin has become too swollen, You should seek medical treatment promptly. If you notice that your dog has muzzle, it is recommended that you take your dog to the veterinarian so that he can be examined and receive appropriate treatment according to the situation.
