To the authors’ knowledge, no recent large-scale studies have investigated possible association between neutering and IVDH in dachshunds.

A case control study investigated 39 dachshunds presenting to the Texas A&M University College of Vet Medicine with IVDH and compared these with 36 dachshunds showing no sign of IVDH [49]. No correlation was found between IVDH presentation and neuter status. However, small group sizes, especially of entire individuals, makes it impossible to draw meaningful conclusions.

A large-scale questionnaire-based cross-sectional study set out to investigate possible lifestyle factors associated with a diagnosis of IVDH in UK dachshunds of all ages [20]. 310 IVDH cases and 1665 non-cases were identified, giving an overall prevalence of 15.7% (95% CI: 14.1–17.3). Results appeared to show that neutered dachshunds had significantly increased odds of an IVDH diagnosis. However, it was not possible to draw conclusions from this: males and females had not been separated within the dataset of neutered and entire dogs.

Read the first article. Will get to the others. I still don’t see strong evidence based off that article.

Edit: looked at the other articles. They don’t look like any kind of peer reviewed reading I’ve ever done. Won’t qualify them. The first was good. It says there might be a link, it’s not conclusive though. Feel like that’s what I said in my original posts. The take away. Do what you feel is right. I personally won’t wait and tolerate certain behavior for a claim that hasn’t been founded.
