Accounting Changes and Error Corrections [Abstract]
Restatement of Previously Issued Financial Statements	Restatement of Previously Issued Financial Statements In the third quarter of fiscal year 2024, we reviewed the accounting treatment related to previously reported sales tax accruals as well as the accounting treatment related to the valuation of the deferred tax asset associated with our acquisition of PetCareRx in April 2023. As a result of this review, management determined that we incorrectly applied United States Generally Accepted Accounting Principles (U.S. GAAP) as it relates to the sales tax liability and improperly valued the deferred tax asset and goodwill included in our consolidated financial statements. We corrected the misstatements relating to sales tax accruals by recording sales tax accruals as of the end of each of the affected periods using a legal liability approach under Accounting Standards Codification Topic 405, Liabilities. The restated sales tax accrual amounts assume that (i) customers who have not yet provided certificates or other documentation of exemption from sales tax are taxable, (ii) total potential interest and penalty assessments may be imposed, and (iii) we will not receive waivers of interest and penalties or other benefits under agreements we may obtain with jurisdictions from our outreach with voluntary disclosures. We will continue to accrue interest on any outstanding liabilities until the voluntary disclosure agreements are settled. These accrual amounts have been, and will continue to be, adjusted in future periods as and if we obtain any waivers of interest and penalties or other benefits from our voluntary disclosures and as and if we obtain additional documentation from customers supporting exemption from sales tax. In addition, we have corrected misstatements relating to the deferred tax asset we recognized in connection with our acquisition of PetCareRx on April 3, 2023. In the accounting for that acquisition, it was determined that we incorrectly valued deferred tax assets associated with loss carryforwards of PetCareRx under section 382 of the Internal Revenue Code. As a result of this error, we recorded a decrease in the amount of our deferred tax assets and a corresponding increase in the amount of goodwill in each of the affected periods. The misstatements that appeared in our previously issued financial statements were material, and we also corrected other immaterial errors. As described in additional detail in the Explanatory Note in our Amendment No. 1 on Form 10-K/A to our Annual Report on Form 10-K for the year ended March 31, 2023, originally filed with the SEC on May 23, 2023, we restated our audited consolidated financial statements as of and for the years ended March 31, 2023, 2022 and 2021, as well as our unaudited condensed consolidated quarterly financial information for the quarterly periods within the fiscal years ended March 31, 2023 and 2022, to reflect the correction of the misstatements relating to sales tax accruals and other immaterial adjustments, and to make corresponding disclosures. We also filed with the SEC (i) an Amendment No. 1 on Form 10-Q/A to our Quarterly Report on Form 10-Q for the three months ended June 30, 2023, originally filed with the SEC on August 2, 2023, to restate our unaudited condensed consolidated financial statements as of and for the three months ended June 30, 2023 and 2022 and (ii) an Amendment No. 1 on Form 10-Q/A to our Quarterly Report on Form 10-Q for the three months ended September 30, 2023, originally filed with the SEC on October 31, 2023, to restate our unaudited condensed consolidated financial statements as of and for the three and six months ended September 30, 2023 and 2022, in each case to reflect the correction of the misstatements relating to sales tax accruals and the valuation of deferred tax assets associated with our acquisition of PetCareRx in April 2023. The restated prior-year results are reflected in the consolidated financial results disclosed within this Annual Report on Form 10-K.
