The acute vomiting dog requires a tiered diagnostic approach that first separates life-threatening surgical emergencies from medical causes, then stratifies medical differentials using targeted testing.
Physical examination is the critical first step. Tachycardia (reference range 80–120 beats/min), dehydration, tacky mucous membranes, abdominal distension, and pain on palpation are the cardinal signs that flag a surgical or hemodynamically unstable patient requiring immediate intervention before further workup.Journal of the… Sudden collapse combined with acute vomiting raises the urgency further — hemorrhagic peritoneal effusion, marked thrombocytopenia, and markedly elevated liver enzymes are findings that can accompany acute hemoabdomen in young large-breed dogs.Journal of the…
Baseline clinicopathologic testing — CBC, serum biochemical profile, and urinalysis — is the standard first diagnostic tier. This combination identifies systemic contributors (hepatobiliary disease, urinary obstruction, metabolic derangements) and flags hematologic abnormalities such as anemia or thrombocytopenia that redirect the differential.Journal of the…+1 Blood gas analysis is appropriate when cardiovascular compromise is present; in one acute abdomen presentation, serum biochemistry and blood gas results were within reference limits despite significant tachycardia and dehydration, illustrating that normal chemistry does not exclude a surgical lesion.Journal of the…
Pancreas-specific lipase measurement is indicated when acute pancreatitis is on the differential, but a positive result does not confirm it as the sole diagnosis. Gastrointestinal foreign body obstruction (GIFBO) is not associated with abnormal point-of-care pancreas-specific lipase results, so an elevated lipase in a vomiting dog should not be used to exclude a mechanical obstruction.Journal of the… Pancreatic lipase immunoreactivity is included in the standard diagnostic panel for acute vomiting at tertiary care facilities alongside CBC, biochemical profile, and urinalysis.Journal of the…
Abdominal imaging is required to differentiate surgical from medical causes and should not be deferred when GIFBO is a differential. Abdominal radiography is the appropriate first imaging modality and is included in baseline evaluation for GI/hepatobiliary presentations.Journal of the…+1 When radiographs are inconclusive or soft tissue detail is needed — particularly in large patients — contrast CT with arterial, portal venous, and delayed phases (using 2 mL/kg IV iodine-based contrast) provides superior characterization of hepatic, vascular, and intestinal structures.Journal of the… Abdominal ultrasonography is an additional diagnostic consideration when radiographs do not yield a diagnosis, and when ultrasound demonstrates thickened muscularis layer, laparoscopic or surgical biopsy is more diagnostic than endoscopic sampling.AAHA Clinical G…
When initial imaging and bloodwork do not identify a cause, endoscopy is the next-tier investigation. Real-time video capsule endoscopy detects surgical and nonsurgical gastric lesions in dogs presenting with acute vomiting and provides data directly applicable to clinical decision-making.Animals Conventional endoscopy and colonoscopy are also listed as additional diagnostic considerations in the GI/hepatobiliary workup.AAHA Clinical G…
Cyclic vomiting syndrome is a diagnosis of exclusion and requires that hematology, biochemistry, imaging, endoscopy, MRI/CSF, and EEG all be unremarkable before it is assigned. Metabolic, GI, and neurologic causes must be fully ruled out; complete symptom-free intervals between episodes distinguish this functional episodic disorder from chronic organic disease.BMC Veterinary…
The diagnostic sequence in brief: physical examination with hemodynamic assessment → CBC, biochemical profile, urinalysis ± blood gas → pancreas-specific lipase when pancreatitis is suspected → abdominal radiographs → abdominal ultrasound (with biopsy guidance if muscularis thickening is found) → contrast CT when soft tissue detail is required → endoscopy/colonoscopy → advanced neurologic imaging if all prior workup is unremarkable.Journal of the…+5
