Dogs generally have more or less bad breath, only the smell is not great, if the dog’s bad breath is obvious, then it may be bad breath caused by oral diseases, such as gingivitis, inflammation of the throat ulcer, oral inflammation or oral calculus. Gastrointestinal diseases such as gastroenteritis, indigestion, and flatulence can also cause bad breath in dogs. Dogs with very bad tartar, due to residual buildup of food debris, or calcium in saliva deposited on the surface of the teeth, can cause strong bad breath. Gingivitis can also cause bad breath in dogs, with symptoms of red, swollen gums, drooling and severe bad breath. If the disease worsens, it can cause teeth to loosen and fall out. Tooth decay occurs on the upper and lower biting surfaces of the gums and molars, where food residue tends to remain, and tooth decay can cause discoloration and cavities with strong bad breath.
