An 11‐year‐old, 4.8‐kg, entire, male Papillon dog presented because of anaemia and polyuria‐polydipsia for 2 months before presentation and sudden dyspnoea. Haematological examination revealed severe non‐regenerative anaemia. Thoracic radiography revealed pulmonary oedema and cardiac enlargement. Echocardiography showed no obvious structural cardiac abnormalities; however, the left ventricular preload and cardiac output were high, and the systemic vascular resistance was low. The dog was diagnosed with high‐output heart failure secondary to non‐regenerative anaemia. Fresh whole blood transfusion following the treatment of congestive heart failure using diuretics and supplemental oxygen was performed. After 5 days, the high‐output heart failure had markedly improved and the clinical signs had resolved; therefore, bone marrow cytological examination was performed, and the patient was diagnosed as presumed pure red cell aplasia. To the best of our knowledge, this is the first report of naturally occurring high‐output heart failure secondary to severe chronic anaemia in dogs.

A 6‐year‐old miniature schnauzer was referred for urolithiasis and perineal swelling, suspicious of urethral trauma. On positive‐contrast cystourethrogram, the dog was diagnosed with rupture of the penile urethra. Temporary urinary diversion was attempted with no improvement. Primary urethral anastomosis was performed, but urine leakage resumed after surgery and led to wound formation in the perineum. Additional surgery was recommended to repair the urethra, but financial constraints prevented further surgery and hospitalisation. The decision was made to attempt an autologous blood urethral patch, mimicking the methodology of autologous blood pleurodesis for persistent pneumothorax. Autologous blood was instilled into the urethra at the site of the urethral tear. Five days after the procedure was performed, positive‐contrast cystourethrogram identified no contrast material outside the boundaries of the urethra. In this dog, performing autologous blood urethral patch resulted in a safe and non‐invasive treatment option for persistent urethral leakage following failure of traditional management.

Equine renal cell carcinoma (RCC) is a rare and poorly understood condition, making the diagnosis challenging. We present a case of a 16‐year‐old Warmblood gelding referred for lameness and suspected pneumonia. The horse exhibited diverse non‐specific symptoms, including pyrexia, coughing, weight loss and lameness. Diagnostic imaging revealed an osseous neoplastic lesion and lung metastasis. Postmortem confirmed metastatic renal carcinoma. This case underscores the difficulty of RCC diagnosis due to non‐specific clinical signs, necessitating a comprehensive approach involving clinical, imaging and histopathological findings. RCC offers limited treatment options as it is typically diagnosed at advanced stages, leading to a poor prognosis and euthanasia. Increased awareness and research are crucial for early detection and better understanding of this rare equine disease.

Idiopathic oculomotor neuropathy is a well‐recognised syndrome in people, and it has also been described in dogs. In dogs, the disease appears to have a good prognosis; however, only reports of a unilateral presentation exist. Evidence of oculomotor dysfunction in cats has been previously associated with intracranial neoplasia, with a poor prognosis. This case report describes the clinical and imaging findings and outcome of a 12‐year‐old, male, neutered, domestic shorthair cat with bilateral mydriasis, unresponsive to light, as the sole clinical sign. Thorough diagnostic investigations led to a diagnosis of bilateral idiopathic oculomotor neuropathy. No treatment was prescribed, and there was no change in the clinical signs with 9‐month follow‐up. To the authors’ knowledge, this is the first report of bilateral idiopathic oculomotor neuropathy in a cat, which, based on this case, suggests a good prognosis with minimal adverse impact on the patient.

Zinc phosphide is a highly toxic rodenticide that leads to organ dysfunction by disruption of oxidative phosphorylation via inhibition of the final enzyme of the mitochondrial transport chain (cytochrome C oxidase). A 5‐year‐old, female, spayed Shiba Inu presented in status epilepticus secondary to ingestion of this poison. The dog developed rapid progressive neurological decline, severe cardiotoxicity and acute liver failure, the latter manifested by hepatic encephalopathy and clinicopathological abnormalities, including coagulopathy, progressive liver enzyme elevations and hyperbilirubinemia, hypoglycaemia, hypoalbuminaemia, hypocholesterolaemia and low blood urea nitrogen. The dog ultimately died after 22 hours of hospitalisation. While this toxicosis is reported in several other species, this is the first case report documenting clinical acute liver failure secondary to zinc phosphide poisoning in a dog. Previous canine reports of zinc phosphide exposure suggest a generally favourable prognosis, whereas this case of toxicity was rapidly fatal, suggesting that reassessment of prognosis secondary to this toxicity is prudent.
磷化锌是一种剧毒杀鼠剂，通过抑制线粒体运输链的最后一种酶（细胞色素 C 氧化酶）来破坏氧化磷酸化，从而导致器官功能障碍。一只 5 岁的雌性柴犬因摄入这种毒药而出现癫痫状态。该犬出现了快速进行性神经功能衰退、严重的心脏毒性和急性肝功能衰竭，后者表现为肝性脑病和临床病理异常，包括凝血功能障碍、进行性肝酶升高和高胆红素血症、低血糖、低白蛋白血症、低胆固醇血症和低血尿素氮。该犬在住院 22 小时后最终死亡。虽然这种中毒在其他几个物种中也有报道，但这是第一例记录狗因磷化锌中毒而继发临床急性肝功能衰竭的病例报告。以前关于犬类接触磷化锌的报道表明预后一般较好，而这一中毒病例却很快死亡，这表明对继发于这种中毒的预后进行重新评估是谨慎之举。

Feline dermatophytosis is a common dermatological manifestation that carries a good prognosis once a proper diagnosis has been achieved. In rare cases, dermatophytosis can manifest as a nodular dermatosis. This condition, known as dermatophytic pseudomycetoma, can be challenging to diagnose and treat. Surgical excision and systemic antifungal therapy are the standard treatments, which generally will carry a good prognosis for the patient. This case report describes a non‐surgical dermatophytic pseudomycetoma, which failed treatment with a singular antifungal agent, but improved when multiple antifungal medications were combined. This case highlights challenges associated with treating a cat with severe dermatophytic pseudomycetoma and concurrent feline leukaemia virus.

The domestic ferret is sensitive to mycobacterial infections, which are likely underdiagnosed. There are limited reports of therapy for mycobacteriosis in ferrets and most have failed. A ferret in poor body condition revealed marked organomegaly on diagnostic imaging. The complete blood count revealed a mild pseudoeosinophilia, which might be attributed to negatively stained bacilli phagocytised by monocytes observed in the blood smear. Ziehl–Neelsen stain was performed and showed acid‐fast bacilli within monocytes. Fine‐needle aspirates of the spleen and liver revealed the same finding. Mycobacterium genavense was identified by PCR and DNA sequencing from peripheral blood. Treatment with rifampicin, clarithromycin and enrofloxacin was initiated. The disseminated mycobacteriosis was suspected from the observation of bacilli on the blood smear. After 16 months, the ferret is still undergoing treatment. To prevent recurrence, continued monitoring of drug toxicity and effective therapy will be maintained even after the resolution of clinical signs (mostly organomegaly).
家养雪貂对霉菌感染很敏感，但很可能诊断不足。有关雪貂霉菌病治疗的报道很有限，而且大多数都以失败告终。一只身体状况不佳的雪貂经影像诊断发现器官明显肿大。全血细胞计数显示有轻度假性嗜酸性粒细胞增多，这可能是由于在血涂片中观察到单核细胞吞噬了阴性染色的杆菌。对其进行了齐氏-奈尔森染色，结果显示单核细胞内存在耐酸性杆菌。脾脏和肝脏的细针穿刺也发现了同样的结果。通过外周血中的 PCR 和 DNA 测序，确定了 Genavense 分枝杆菌。患者开始接受利福平、克拉霉素和恩诺沙星治疗。通过观察血涂片上的杆菌，怀疑患上了播散性分枝杆菌病。16 个月后，雪貂仍在接受治疗。为防止复发，即使在临床症状（主要是器官肿大）消失后，也要继续监测药物毒性并进行有效治疗。

This report describes the use of an ultrapotent, opioid‐free anaesthesia with an infusion of butorphanol, ketamine and guaifenesin in two captive adult male greater one‐horned rhinoceros (Rhinoceros unicornis). Animals were premedicated intramuscularly with azaperone (0.05 mg/kg), butorphanol tartrate (0.05 and 0.02 mg/kg, respectively) and an α2‐agonist (detomidine 0.02 mg/kg and medetomidine 0.01 mg/kg, respectively). Once sternolaterally recumbent, rhinoceros were induced with intravenous ketamine (0.02 and 0.05 mg/kg, respectively) and midazolam (7.0 and 8.0 μg/kg, respectively). Intravenous infusions of guaifenesin (15.1 and 25 mg/kg/h, respectively) and of ketamine (22.5 and 29.1 μg/kg/h, respectively) and butorphanol (15.7 and 20.3 μg/kg/h, respectively), allowed stable anaesthesia maintenance for dental procedures to take place. Supplemental boluses of ketamine and α2‐agonist were required during noxious stimulation in both cases. Animals were reversed with intramuscular atipamezole (0.07–0.08 mg/kg) and naltrexone (0.06–0.08 mg/kg), with or without flumazenil (0.10 μg/kg), allowing smooth and quick recovery.

A 1‐year‐old, female, spayed dachshund presenting with clinical signs associated with cholangiohepatitis and cholangitis was found to have synthetic linear foreign material causing a common bile duct obstruction. The patient underwent a cholecystectomy, and foreign material was removed from the common bile duct via retrograde flushing into the duodenal papilla and manual retrieval. At the 6‐month post‐operative follow up visit, the patient had an improved cholestatic hepatopathy, with only a mild alkaline phosphatase elevation, moderate dilation of the common bile duct on ultrasonography, and was doing clinically well at home. 8 months post‐operatively, the patient re‐presented for an episode of septic cholangiohepatitis, with linear foreign material visualised within a dilated common bile duct on ultrasound. This episode was medically managed and was resolved with a 2‐week course of antibiotics. 1.5 years post‐operatively, the patient is doing clinically well, but continues to have persistent, moderate elevations of alanine transaminase and alkaline phosphatase.

A 12‐day‐old, male Holstein Friesian calf was presented to the hospital due to progressive ataxia and tremors since birth. A diffuse central nervous system disorder primarily affecting white matter was suspected based on clinical neurological examination. Blood tests were unremarkable, except for positive serology for Schmallenberg virus. Magnetic resonance imaging of the brain demonstrated severe, diffuse abnormalities primarily affecting the white matter regions of the encephalon and cranial cervical spinal cord, consistent with leukoencephalomyelopathy. Euthanasia was performed at 8 weeks of age after no clinical improvement. A postmortem examination was performed. Histopathological examination of the central nervous system revealed changes compatible with hypomyelinating leukodystrophy, with no signs of infectious agents observed. The disorder was considered most likely to be hereditary, as Schmallenberg virus infections during pregnancy in cattle have not been reported to result in such clinical, magnetic resonance imaging or histopathological findings, and no viral genomic material was identified with polymerase chain reaction.
