“…However, strict criteria to define a breed as chondrodystrophic are lacking, 1,9,27 and it is currently unclear whether English Cocker Spaniels should be considered chondrodystrophic. [1][2][3][4]6,12,13,22,27,28 It has been demonstrated that English Cocker Spaniels have a less pronounced chondrodystrophic phenotype than Dachshunds. 5 The vertebral column length relative to the height at the withers (most dorsal aspect of the shoulders between the scapulae) was much higher in Dachshunds than in English Cocker Spaniels, but was similar between English Cocker Spaniels and German Shepherd Dogs.…”

“…3,4,[8][9][10][11][12] English Cocker Spaniels are also predisposed to IVDE, and this breed is among the 7 breeds at highest risk for this disorder. 2,5,6,13,14 Although anecdotal information suggests a higher incidence of lumbosacral IVDEs in English Cocker Spaniels than in other dog breeds, 15 little is known about characteristics of thoracolumbar and lumbar IVDE in this breed.…”

OBJECTIVE To assess the anatomic distribution of thoracolumbar and lumbar intervertebral disk extrusions (IVDEs) in English Cocker Spaniels as compared with findings in Dachshunds and to characterize clinical findings in English Cocker Spaniels with thoracolumbar or lumbar IVDEs affecting various regions of the vertebral column. DESIGN Retrospective observational study. ANIMALS 81 English Cocker Spaniels and 81 Dachshunds with IVDEs. PROCEDURES Signalment, clinical signs, neurologic examination findings, and affected intervertebral disk spaces (IVDSs) were recorded for both breeds. Management methods and outcomes were recorded for English Cocker Spaniels. Lesions were categorized as thoracolumbar (IVDSs T9–10 through L1–2), midlumbar (L2–3 through L4–5), or caudal lumbar (L5–6 through L7–S1). RESULTS Midlumbar and caudal lumbar IVDEs were significantly more common in English Cocker Spaniels than in Dachshunds. English Cocker Spaniels with caudal lumbar IVDEs had a longer median duration of clinical signs before evaluation and more commonly had unilateral pelvic limb lameness or spinal hyperesthesia as the predominant clinical sign than did those with IVDEs at other sites. Those with caudal lumbar IVDEs less commonly had neurologic deficits and had a higher median neurologic grade (indicating lesser severity), shorter mean postoperative hospitalization time, and faster mean time to ambulation after surgery than those with other sites affected. These variables did not differ between English Cocker Spaniels with thoracolumbar and midlumbar IVDEs. CONCLUSIONS AND CLINICAL RELEVANCE Caudal and midlumbar IVDEs were more common in English Cocker Spaniels than in Dachshunds. English Cocker Spaniels with caudal lumbar IVDE had clinical signs and posttreatment responses that differed from those in dogs with midlumbar or thoracolumbar IVDE.

“…Ultimately an ideal situation would be a randomized controlled study design in dogs undergoing spinal decompression with application of one of the prophylactic techniques along with a control group ultimately with comparison among groups. When considering the ease that PLDA may be performed in conjunction with other decompressive surgical procedures, level II evidence could be easily obtained as demonstrated by Brisson et al [17] in the case of fenestration. This accumulation of evidence with regard to PLDA may be obtained in an effi cient, easy and cost-effective manner allowing a signifi cant " boost " to the veterinary literature.…”

“…The results suggested that multiple-site fenestration may decrease the rate of recurrence of IVDD in dogs undergoing decompressive surgery. In addition, recurrence is more likely in dogs with radiographic evidence of disc mineralization, and dogs with multiple-site fenestration from T11 to L4 will likely have recurrence at the L4 -L5 and L5 -L6 location [17] .…”

Objective: To review and evaluate the literature reporting results of prophylactic surgical procedures for Hansen ' s type I intervertebral disc disease. Study design: Systematic literature review. Methods: Online bibliographic searches of abstracts through PubMed and the Veterinary Information Network (VIN) were performed using the searchable term " canine intervertebral disc disease and recurrence " . The resources were evaluated in regard to the ability of the retrieved references to directly address the clinical question as follows: which prophylactic technique when considered with or without surgery will consistently reduce or eliminate the recurrence of clinical signs associated with Hansen ' s type I intervertebral disc disease. All studies were compared and evaluated with regard to study design, technique utilized, short and long-term outcome, and evidence classifi cation. Results: An online bibliographical search was performed in PubMed using the full search term of " canine intervertebral disc disease and recurrence " resulted in 20 total sources, and of those sources 13 contained information pertaining to the clinical question. The same search term when used in the VIN search engine under the classifi cation of journal abstracts resulted in 43 total results with 18 applicable resources. In review of both searches, 13 resources were listed in both searches. Of the 18 obtained by the VIN search 14 were available in the English language. No resources were included in class I level of evidence, and only one was considered as class II level of evidence. As for the remaining studies, three results were classifi ed as class III studies, and the remaining reports were classifi ed as class IV level of evidence. Conclusion:Although direct extrapolation of the evidence provided by the search to the clinical scenario is not possible, this review will hopefully provide the basis for development of a randomized controlled study to provide for a clear need in evidence for prevention of intervertebral disc extrusion in dogs.Keywords: evidence-based medicine (EBM); intervertebral disc disease; percutaneous laser disc ablation (PLDA); recurrence; fenestration; hemilaminectomy; dog; spinal cord.
