Documented health information for Mochi, a male white miniature Pomeranian, including specialist findings, test results and dated updates.
CT found no evidence of a macroscopic portosystemic shunt, meaning no visible large blood vessel bypassing the liver. Because some signs had improved with treatment, DWR considered another form of hepatic dysfunction possible, such as portal vein hypoplasia without portal hypertension.
The report did not confirm microvascular dysplasia (MVD). An elevated bile acid result on its own does not establish that diagnosis.
| Sample | Result | Laboratory reference range | Compared with range |
|---|---|---|---|
| Before food (pre-prandial) | 3.2 µmol/L | 0.1 to 5.0 µmol/L | Within range |
| After food (post-prandial) | 63.6 µmol/L | 0.1 to 10.0 µmol/L | Above range |
Repeat bile acids were pending when the report was written. No later result is included in the material reviewed for this page.
Background reading: Merck Veterinary Manual on hepatic portal venous hypoperfusionSevere deviation of the nasal septum and a moderately elongated soft palate. DWR considered his airway shape and brachycephalic obstructive airway syndrome (BOAS) the likely explanation for his respiratory signs.
About BOAS: American College of Veterinary SurgeonsSeveral skull sutures had not fused, leaving open fontanelles. Imaging also showed an enlarged opening at the base of the skull, mild kinking of the brainstem and a malformed tail vertebra. Their contribution to his symptoms was uncertain and further imaging was discussed.
Teeth were crowded, rotated or distorted, with retained baby teeth and missing adult teeth. DWR thought the dental changes could cause discomfort and reduced appetite. The jaw shape changes were considered likely incidental.
Small mineralised areas in the left kidney and bladder were interpreted as stones. Calcium oxalate was raised as a possibility and the composition was not confirmed. The May urine sample showed no evidence of infection or inflammation.
Symmetrical hair loss remained unexplained. Alopecia X was listed as a possibility and was not a confirmed diagnosis.
Both testes were within the abdomen at the time of CT. Both kneecaps were prone to slipping out of place. These describe the May 2025 examination and not his current neutering or surgical status.
Several of these signs were not seen during the hospital stay.
Lactulose, amoxicillin-clavulanate and a hepatic diet were started for suspected liver dysfunction. The DWR report later recorded improvement in drinking, urination and head jerking.
Investigation at DWR including CT. Multiple congenital differences were recorded and no macroscopic liver shunt was seen. Repeat bile acids, vitamin B12 and a urine protein-to-creatinine ratio were pending when the report was written on 17 May.
Right-eye episode.
Recurrence of the right-eye problem.
The family reported attending an eye specialist at Granta, where a dental or orbital cause was discussed. No written conclusion was available for this summary.
Fall from the sofa, followed by an injury to the left eye. This is a separate problem from the right-eye episodes above.
Recheck of the left eye. The vet was reportedly not concerned and advised allowing it to heal.
Family update: the left-eye injury had improved over many weeks and the swelling below the eye became barely visible in about five weeks. This is an owner-reported recovery update and not a new written diagnosis.
DWR advised continuing lactulose as needed, stopping amoxicillin-clavulanate (Kesium) and considering alternative foods. Pain relief and anxiety medication were prescribed for use as needed.
Kesium was used again after the May 2025 discharge. The family's July 2026 form also listed lactulose, melatonin and several renal or hepatic foods. These are dated reports of use.
Repeat bile acids, vitamin B12 and a urine protein-to-creatinine ratio were pending on 17 May 2025. Later results are not in the material reviewed for this page.
Current diet and medication are matters for Mochi's treating vet.
