SummaryTo find the most common diagnoses of dogs where vomiting was the main reason for referral and to determine the usefulness of various diagnostic investigations.213 dogs referred for vomiting as main or one of the main causes were analysed retrospectively. Diagnosis was reassessed and categorized into six groups, namely gastrointestinal, systemic, non-gastrointestinal abdominal, neurological, miscellaneous or no diagnosis. All diagnostic investigations were reviewed to assess their usefulness to reach a diagnosis. The usefulness of a diagnostic investigation was scored into the following four groups: enabled a diagnosis; assisted a diagnosis; no assistance, diagnosis reached by another procedure; no assistance, no final diagnosis made.In 203 dogs (95.3%) a diagnosis was reached and was categorised as gastrointestinal (43.7%), systemic (27.7%), non-gastrointestinal abdominal (16.4%), neurological (1.4%) and miscellaneous (6.1%). Laboratory tests enabling or assisting a diagnosis as blood tests in 12.2%; 26.8%, as faecal analysis in 6.6%; 1.4%, as ultrasound in 5.2%; 17%, as cytology in 3.3%; 4.2%, as urinalysis in 2.3%; 9.9% and as radiographs in 1.9%; 8.5% of all cases.Overall, there was a high incidence of dogs referred for vomiting with non-gastrointestinal diseases. Amongst them, renal problems were most commonly seen, which emphasises the need to perform a urinalysis in most dogs with vomiting as major complaint. However, vomiting can be due to a large variety of underlying pathophysiological mechanisms and no single problem seems to be much more common compared to other problems in a referral institution.Based on this investigation it is not possible to clearly state a most useful single diagnostic test in dogs with emesis, however, it could clearly been shown that more than one test is often needed to reach a final diagnosis. This is important for owners to understand but also for referring veterinarians.
