Understanding Canine Kidney Failure: Causes, Symptoms,
1. Gastric Disorders: Sour and Foul Odor. Halitosis accompanied by a sour smell often stems from dental issues such as gingivitis and excessive tartar, which create a breeding ground for bacteria in the mouth. However, when the pyloric part of the stomach narrows or becomes obstructed, food can remain in the stomach for an extended period, leading to regurgitation of stomach contents that contain acid and an unpleasant smell. These substances then escape through the mouth, contributing to the sour and foul odor.
2. Liver Conditions: Rotten Egg Smell. A smell resembling that of rotten eggs is often an indicator of liver problems. When liver disease is accompanied by impaired gastrointestinal repair, it can lead to insufficient stomach acid production. This allows food residue to become a breeding ground for bacteria, some of which may adhere to the back of the tongue or the oropharynx, resulting in a smell akin to that of rotten eggs.
3. Pulmonary Diseases: Foul Fishy Odor. When suffering from conditions like lung abscesses, pulmonary infections, or bronchiectasis, a fishy smell may emanate from the mouth. This occurs due to inflammation in the lungs, which prevents mucus from being expelled normally, leading to its accumulation and subsequent decay.
4. Kidney Failure: UrineLike Smell. Kidney failure, characterized by insufficient urine production or oliguria, prevents the normal excretion of waste products. Certain toxic substances accumulate in the blood, and in cases of chronic nephritis or kidney disease, this can lead to a urinelike smell in the mouth.
5. Diabetes: Spoiled Apple Smell. When blood sugar levels are elevated, the mouth can produce a sour, spoiled applelike odor. When this smell is detected, it indicates that the dog's body has a high concentration of ketones, approaching or reaching levels associated with diabetic ketoacidosis.
6. Renal Failure: Fishy Taste. In cases of renal failure or uremia, the impaired excretion of urea can lead to a fishy taste in the mouth and throughout the body. A treatment recipe for halitosis caused by gastric disorders: Use 3 grams of star anise and 5 grams of osmanthus, soak in boiling water for 5 minutes, and let the dog drink it. Generally, after 7 days of continuous use, significant improvement can be observed.
In this case, if a dog's halitosis is accompanied by a fishy smell, indicating renal failure, pet owners should carefully differentiate and use this information as a reference.
