Causes of Dog Vomiting
Check out this answer from Consensus:
Vomiting in dogs can result from a wide range of causes, including dietary indiscretion, infections, metabolic diseases, physical obstructions, and systemic conditions. Accurate diagnosis often requires a combination of clinical history, physical examination, and diagnostic tests. Understanding the underlying cause is essential for effective treatment and management of vomiting in dogs.
By recognizing the diverse etiologies of vomiting, veterinarians can better tailor their diagnostic and therapeutic approaches to improve outcomes for their canine patients.
Vomiting in dogs is a common clinical issue that can arise from a variety of causes. Understanding these causes is crucial for effective diagnosis and treatment. This article explores the primary causes of vomiting in dogs, drawing on recent research findings.
Gastrointestinal Causes
Dietary Indiscretion
One of the most common causes of vomiting in dogs is dietary indiscretion, which includes the ingestion of inappropriate food or non-food items. Studies have shown that dietary abnormalities account for a significant percentage of vomiting cases in dogs1 5.
Infections
Gastrointestinal infections, such as those caused by Parvovirus, are also a prevalent cause of vomiting. Parvovirus infection alone was responsible for 24-44% of vomiting cases in some studies2 5. Other infections, including parasitic infestations, can also lead to vomiting5.
Gastric Disorders
Gastric disorders, including gastritis and gastric ulcers, are significant contributors to vomiting. Helicobacter spp. infections, for instance, have been linked to chronic vomiting and gastritis in dogs8.
Systemic Causes
Metabolic Diseases
Metabolic diseases such as Addison’s disease, renal disorders, and hepatic disorders can lead to vomiting. Renal problems, in particular, are frequently observed in vomiting dogs, emphasizing the need for comprehensive diagnostic tests, including urinalysis4 5.
Pancreatitis
Pancreatitis is another systemic condition that can cause vomiting. It is often associated with other symptoms such as abdominal pain and lethargy1.
Physical Obstructions
Foreign Bodies
Physical obstructions, such as ingested foreign bodies, can cause acute vomiting. These cases often require immediate veterinary intervention to prevent severe complications3.
Tumors
Tumors in the gastrointestinal tract or other abdominal organs can also lead to vomiting. These cases are typically diagnosed through imaging techniques such as radiographs and ultrasounds3 4.
Neurological Causes
Vestibular Disease
Neurological conditions, including vestibular disease, can cause vomiting due to the disruption of the normal balance and coordination mechanisms in dogs4.
Other Causes
Pericardial Effusion
Pericardial effusion, a condition where fluid accumulates around the heart, has been associated with vomiting in dogs. This condition can lead to cardiovascular decompensation and requires prompt medical attention7.
Canine Enteric Coronavirus
Recent outbreaks of prolific vomiting in dogs have been linked to canine enteric coronavirus. This virus was significantly associated with gastroenteric disease in affected dogs, highlighting the importance of surveillance and early detection systems9 10.
