If your dog has bad breath and is not eating, it is recommended that you first check your dog’s mouth carefully. If the teeth are white and the gums are pink, then the main consideration is oral odour due to fermented food residues or intestinal digestive disease. If the roots of the teeth are yellow and the gums are flushed, then consider bad breath caused by oral diseases such as calculus and inflammatory oral cavities. The main factors of oral diseases that cause bad breath in dogs are: ①. Inflammation of the mouth caused by eating bones or sharp objects that scratch the mucous membrane of the mouth. ②. The dog does not brush its teeth for a long time and food residues adhere to the surface of the teeth, resulting in dental calculus (yellowish-white or yellowish-black, hard) from plaque mineralisation. ③. Severe gingivitis leading to an outbreak of periodontitis and acute or chronic inflammation of the alveolar bone tissue, which if left untreated can cause gum atrophy and loose teeth. ④. Dogs have a single diet and lack vitamins.
