Diagnosis of Common Symptoms in Dogs

Systemic symptoms

1. Suddenly not eating is seen in acute infectious hepatitis, acute leptospirosis, acute poisoning, acute enteritis, intestinal occlusion, intestinal torsion.
2. Loss of appetite can be seen in chronic infectious diseases, intestinal parasitosis, chronic gastroenteritis, abnormal secretion of digestive juices, gastrointestinal flora imbalance, cancer, alveolar osteochondritis dissecans, in addition, excessive heat, excessive exercise, motion sickness, before and after childbirth may appear loss of appetite.
3. Eating a lot but losing weight is mostly due to nutritional deficiencies or disorders, the presence of a large number of intestinal parasites, chronic renal insufficiency, malabsorption symptoms (e.g., chronic enteritis, bile, pancreatic fluid secretion disorders) and so on. It is also seen in excessive exercise, sleep deprivation, extensive eczema, and abnormal hormone secretion (e.g., hyperthyroidism).
4. Increased desire to drink is seen in rabies, diabetes mellitus, urosepsis, liver disease, cancer, increased urination, eating too much dry food, acute gastroenteritis, severe vomiting, dysentery, dehydration renal dysfunction, and too much salt in food.
5. Vomiting after drinking water is seen in acute leptospirosis, acute nephritis, pyloric spasm, cerebral hemorrhage, food poisoning, drug poisoning, intestinal folding, and so on.
6. Vomiting immediately after eating is seen in food overdose, ingestion of foreign body or uncomfortable food, acute pharyngolaryngitis, intestinal obstruction, ascariasis, bile duct sphincter spasm, and so on.
7. Vomiting with fever is commonly seen in canine distemper, canine infectious hepatitis, canine microvirus disease, food poisoning, acute nephritis.
8. Vomiting from eating vomit is often caused by eating too much, too much fiber in the food and overburdening the stomach. It is also caused by exercising right after eating. At this time, dogs often eat vomit. In addition, when suffering from pharyngitis, there is also the phenomenon of eating vomit.

Amyloid white eye droppings are most often seen with intestinal parasites or chronic gastrointestinal disease, but usually without signs of conjunctival congestion.
13. The eyes also sting and tear when infectious hepatitis is present. In addition, tearing occurs when conjunctival puffiness is caused by phthisis or plant allergies.
14. Nose tip dryness Dogs with colds, infectious diseases and other feverish diseases that occur, dehydration, defecation can appear dry nose tip, the condition is serious, the end of the nose hardening and even produce cracks.

Bad breath occurs in infectious diseases such as canine distemper, canine infectious hepatitis, leptospirosis, and nutritional disorders, uremia and other systemic diseases. Acetone odor in diabetes; putrid odor in necrotizing pneumonia; ammonia odor in uremia.
2. Excessive salivation stomatitis, dental disease, foreign bodies in the mouth, fracture of the jaws, paralysis of the lips, tongue, and throat, salivary secretion of bitter-smelling medicines, motion sickness and seasickness, and fear. Spasmodic episodes The reflex action of seeing food can all result in salivation.
3. Foaming at the mouth canine distemper, canine filariasis, cerebral anemia, etc., caused by epileptic seizures, convulsions caused by hypokalemia, pesticides, insecticides poisoning, etc. will be foaming at the mouth.
4. Diarrhea acute enteritis, canine distemper, canine infectious hepatitis, leptospirosis canine microvirus disease, food poisoning, gastrointestinal ulcers, pancreatic insufficiency of secretion, picking up too much fat or too much milk, etc., can cause diarrhea.
5. Blood in the stool acute and chronic enteritis, ulcerative enteritis, intestinal tumors, canine microvirus disease, leptospirosis, food poisoning, intestinal parasites (hookworms, coccidia, etc.) can lead to intestinal mucosal bleeding, discharge of bloody feces.

Seizures can be caused by distemper, tuberculosis, cardiovascular disease, uremia, hypoglycemia, hypokalemia, pregnancy toxemia, endocrine dysfunction, and various types of poisoning. In addition, peripheral nerve injury, skin disease, intestinal parasitosis and allergic reactions. They can also cause reflex epilepsy.
