A 9-year-old Yorkshire terrier was brought to the emergency department for inability to maintain the correct station with acute onset. Neurological examination showed a non-ambulatory tetraparesis, spontaneous proprioceptive deficit in all limbs, and decreased flexor reflex in the forelimbs. The neurological symptoms suggested a cranial cervical spinal cord with suspicion of spinal shock. The clinical differential diagnoses included degenerative (intervertebral disc extrusion), vascular, inflammatory, or neoplastic disease. No pathological findings were evident in the hematobiochemical tests or in the radiograph examination. MRI examination of the cervical spine showed the presence of two adjacent hydrated nucleus pulposus extrusions at C3-C4 and C4-C5 tracts. Treatment included analgesic and non-steroidal anti-inflammatory therapy; movement restriction was initially necessary, followed by physiotherapy. Follow-up at 4 weeks showed complete recovery. A telephone follow-up after 3 months with the owner confirmed the absence of symptoms. This article reports the first double cervical HNPE case in a dog, adding the possibility that the disease may present in this form and the success of conservative treatment as described in the literature.

The information available on cervical myelopathies (CMs) and cervical pain (CP) in non-chondrodystrophic breeds remains limited compared to chondrodystrophic breeds. The expression of CP in CMs may depend on lesion type, severity and onset of clinical signs. This retrospective single-centre study reviewed the medical records of 112 purebred non-chondrodystrophic dogs referred for neurological evaluation, in which C1-T2 lesions were subsequently confirmed by magnetic resonance imaging (MRI). Clinical onset was categorised as acute (≤7 days) or chronic (>7 days). Neurological grade was classified into four neurological groups (G1–G4). CP was graded using a study-specific, non-validated five-point ordinal clinical scale. Multifactorial analysis of variance (ANOVA), odds ratios with 95% confidence intervals, and multivariable binomial logistic regression were performed. ANOVA showed significant effects of group (p < 0.0001), disease category (p < 0.05), and clinical onset (p < 0.02) on CP scores. Post-hoc comparison showed significantly lower CP scores in chronic onset than in acute onset (p < 0.0001). Acute onset was associated with CP in G2 (OR = 71.0; p < 0.0002) and remained associated with CP after adjustment for groups (adjusted OR = 4.42; 95% CI: 1.28–15.28; p = 0.019). These findings suggest that clinical onset may contribute to CP expression in non-chondrodystrophic dogs with CMs. Acute onset, particularly in ambulatory myelopathic patients, appears more frequently associated with CP. However, due to the retrospective design, the heterogeneous diagnostic composition, and the study-specific nature of the CP score, these associations should be interpreted cautiously.
