Business Combination and Asset Acquisition [Abstract]
Acquisitions	AcquisitionsDuring the first quarter of fiscal 2022, we acquired substantially all of the assets of Miller Vet Holdings, LLC, a multiregional veterinary distributor, for total cash consideration of $19,793 and liabilities assumed of $6,395. We have included its results of operations in our financial statements since the date of acquisition within the Animal Health segment. This acquisition is expected to grow our presence in the companion animal market and drive increased operating leverage and synergies. The accounting for the acquisition is not complete because certain information and analysis that may impact our initial valuations are still being obtained or reviewed. As of July 31, 2021, we have recorded $14,000 of identifiable intangibles, $1,063 of goodwill, and net tangible assets of $4,730 in our condensed consolidated balance sheets related to this acquisition. The acquisition did not materially impact our financial statements, and therefore pro forma results are not provided.Technology Partner Innovations, LLC ("TPI")In fiscal 2019, we entered into an agreement with Cure Partners to form TPI, which offers a cloud-based practice management software, NaVetor, to its customers. Patterson and Cure Partners each contributed net assets of $4,000 to form TPI. We determined that TPI is a variable interest entity, and we consolidate the results of operations of TPI as we have concluded that we are the primary beneficiary of TPI. During the three months ended July 31, 2021 and July 25, 2020, net loss attributable to the noncontrolling interest was $194 and $205, respectively, resulting in noncontrolling interests of $1,261 on the condensed consolidated balance sheets at July 31, 2021.
