An 11‐month‐old Border Collie dog presented with recurrent fever since the age of 3 months. Clinical examination revealed stunted growth, facial dysmorphism, fever, oral and third eyelid ulcerations and stiff gait with tarsal hyperlaxity. Clinicopathologic testing revealed neutropenia with normal neutrophil maturation in the bone marrow, ulcerative neutrophilic stomatitis and glossitis and a nonperforating duodenal ulcer. Genetic testing showed a mutation in the vacuolar protein sorting‐associated protein 13B gene, establishing a diagnosis of trapped neutrophil syndrome. Steroid therapy was not prescribed due to the presence of a duodenal ulcer. Two weeks later, antibiotics and omeprazole facilitated a mild clinical improvement with relapse; euthanasia was subsequently elected. This case highlights clinical signs not previously described in dogs but known in humans with Cohen syndrome, including buccal ulcerations or joint hyperlaxity. This is also the first description of this disease in France, where Border Collies are commonly bred.

A 4‐year‐old American Pitbull terrier presented for acute onset of a honking cough, vomiting and anorexia. Thoracic radiographs revealed tracheal narrowing consistent with a mass effect or tracheal collapse. The dog was hospitalised but acutely developed respiratory distress, syncope and pale mucous membranes. Moderate pleural effusion and a heart base mass were noted on echocardiographic examination as well as evidence of cardiac tamponade. Coagulation times were severely prolonged. After additional discussion with the owners, rodenticide exposure was considered possible. The owners elected humane euthanasia. A necropsy revealed gross evidence of intrathoracic haemorrhage and a heart base mass consistent with a haematoma. There was no evidence of neoplasia on histopathological evaluation of the tissues. A final diagnosis of rodenticide intoxication was made. This case report demonstrates the importance of considering anticoagulant rodenticide intoxication in patients with a history of pericardial effusion. It is also important to consider a haematoma as a differential diagnosis when a heart‐associated mass is visualised in patients with pericardial effusion.

A 4‐month‐old female entire Dalmatian was presented for persistently excessive ceruminous discharge, suspected left aural malformation and decreased hearing. Otoscopic examination of the left ear showed a normal external meatus with an abnormal ending of the ear canal in a cul‐de‐sac. Computed tomography (CT) study of the head showed a diffusely tortuous and convoluted external ear canal with saccular distension and a stenotic area with the presence of a septum. Based on the clinical presentation and imaging findings, total ear canal ablation and lateral bulla osteotomy were performed. Macroscopically, the ear canal appeared to be sigmoid, as in the CT study. Notably, in the stenotic area, there was a membrane separating the vertical and horizontal ear canals. The histopathology of the external ear canal was consistent with that of hyperplastic otitis externa. No growth was observed on bacterial culture. The dog recovered uneventfully and no abnormalities were detected on re‐examination 2 weeks post‐surgery.

We monitored the bovine leukaemia virus (BLV) proviral load (PVL) in peripheral blood lymphocytes (PBLs) and the PBL counts in BLV‐infected cattle on a dairy farm in Japan to determine the changes in PVL with the progression of lymphocytosis. A total of 25 BLV‐infected Holstein cattle at a dairy farm were followed up from May 2015 (0 month) to April 2016 (11 months). PBL counts and PVL were measured three times in 25 cattle. Based on their PBL counts, five cattle with normal PBL (≤7500 cells/µL) at 0 month but high PBL (>7500 cells/µL) at 11 months were classified as the increased group. All cattle in the increased group showed increased PVL compared to asymptomatic aleukaemic carriers at 11 months. This study revealed increases in PVL with the progression of lymphocytosis, suggesting that cattle with progression of lymphocytosis should be segregated from BLV‐negative cattle as soon as possible.

An 8‐year‐old male German Shepherd dog with a history of dyschezia, tenesmus and perineal swelling for 1 month was referred. The dog was known to be unilaterally abdominal cryptorchid. The normally descended testis had been surgically removed a few years ago. On physical examination, a firm, non‐painful, irreducible mass was palpable in the left perineal region. Digital rectal examination revealed rectal deviation, and the pelvic diaphragm was absent on the left. The prostate gland was normal upon palpation. Abdominal radiography revealed that the urinary bladder was present in the caudal abdomen. Based on clinical, laboratory and imaging findings, a diagnosis of perineal hernia was made. Surgical exploration revealed the presence of left spermatic cord torsion in the perineal hernia. The testis was removed, and internal obturator muscle transposition was performed for herniorrhaphy. The dog had an uneventful recovery, and the results of re‐examinations 10 days, 6 months and 12 months later were normal.

An incidental testicular torsion was discovered during orchiectomy of an approximately 4‐month‐old intact male kitten. His spermatic cord was twisted numerous times, which caused necrosis and swelling of the right teste. Despite these changes, the patient had no signs of pain or clinical signs typical of testicular torsion that is seen in other species. The owner of the kitten reported that the kitten was eating normally and did not show any signs of pain. The physical examination of the kitten did not reveal any tenderness upon palpation of the enlarged testicle. This case illustrates that testicular torsion is possible even in the absence of pain or discomfort in cats.

Four Japanese Spitz dogs between 5 and 11 months old were presented for acute dyspnoea. Thoracic radiographs and CT identified bilateral pneumothorax and pulmonary cavitary lesions. The median lesion size was 30 mm (range 7‒50 mm). After initial stabilisation, one dog underwent median sternotomy, while three dogs underwent intercostal thoracotomy. Surgical exploration found grossly haemorrhagic pulmonary bullous lesions in all cases. Histopathology revealed blood-filled cavities with interstitial fibrosis and pneumocyte hyperplasia. Dyspnoea recurred in all dogs postoperatively, with recurrence of lesions confirmed either radiographically or via CT in three of four cases. The median time from surgery to recurrence of pneumothorax was 9 days (range 5‒15 days). The mortality rate was 100%, and the median postoperative survival time was 22 days (range 5‒558 days). This report aims to raise awareness of this group of dogs presenting with spontaneous pneumothorax at a young age and with high recurrence rates despite surgery, contrary to the literature.

A male pot-bellied pig was presented for left thoracic limb lameness. A fracture of the olecranon apophysis with displacement was diagnosed, and fracture stabilisation was performed under general anaesthesia. After anaesthetic induction, an axillary brachial plexus nerve block (BPB) with bupivacaine was performed using a portable ultrasound device and a nerve locator. Heart rate and blood pressure were monitored for nociception and the need for analgesic intervention during the procedure. No analgesic intervention was deemed necessary, as the pig did not meet predefined nociceptive thresholds. The pig recovered from general anaesthesia uneventfully without clinical signs of pain or complications. The affected limb was knuckled and lacked conscious proprioception immediately after recovery. Sixteen hours after BPB, knuckling resolved, and normal conscious proprioception was observed. No obvious adverse effects from BPB were noted. The combination of ultrasound and nerve stimulator-guided BPB with bupivacaine was successful in a pig.

A 2-year-old, male, intact dog presented with a history of stertorous breathing since infancy, unresponsive to antibiotic therapy. On rostral rigid endoscopy, there were no remarkable findings. However, computed tomography revealed bilateral atresia of the nasal choanae, with focal hyperossification and severe narrowing, with accompanying hypoventilation of the nasopharynx. Retrograde flexible nasopharyngoscopy confirmed the severe partial choanal atresia. Surgical intervention was declined by the owner due to reasonably acceptable quality of life; therefore, only environmental modifications and symptomatic care have been implemented so far.

A 5‐year‐old female neutered Podenco Canario dog presented with a moderate pleural effusion and subsequently underwent placement of bilateral thoracic drains. Pre‐medication consisted of intravenous medetomidine (2 µg/kg) and methadone (0.2 mg/kg), followed by induction with propofol (2.1 mg/kg, via intravenous administration). Anaesthesia was maintained with isoflurane in 100% oxygen. The modified Seldinger technique was used to place bilateral small‐bore, wire‐guided thoracic drains. During placement of the first chest drain, the dog developed sinus arrest. It is suspected that there was direct vagal nerve stimulation by the guide wire during placement, leading to severe bradycardia and subsequent sinus arrest that was responsive to atropine. It is important to note that the definitive cause of the transient cardiac arrest could not be ascertained. It is possible that this is a rare complication of thoracic drain placement, warranting further research in this area.
