OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation and Consolidation	The accompanying interim Condensed Consolidated Financial Statements are unaudited. The interim unaudited Condensed Consolidated Financial Statements have been prepared on a basis consistent with the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include normal, recurring adjustments, necessary to present fairly the financial position of the Company as of September 30, 2022, and the results of our operations and statements of stockholders' equity for the three and nine months ended September 30, 2022 and 2021, and cash flows for the nine months ended September 30, 2022 and 2021. The unaudited Condensed Consolidated Financial Statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to such rules and regulations. Our unaudited Condensed Consolidated Financial Statements include our accounts and the accounts of our wholly-owned subsidiaries since their respective dates of acquisitions. All intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the full year or any future period, particularly in light of the COVID-19 pandemic and its effects on the domestic and global economies as described below. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2021 and other financial information filed with the SEC. Beginning in the first quarter of 2020, to limit the spread of COVID-19, governments took various actions including the issuance of stay-at-home policies and social distancing procedures and guidelines, causing some businesses to adjust, reduce or suspend business and operating activities. Veterinary care is widely recognized as an "essential" service for pet owners, and veterinarians continued to deliver essential medical care for sick and injured pets. We are unable to predict with certainty the effects of the COVID-19 pandemic on our customers, suppliers and vendors, as well as the actions of governments, and when and to what extent normal economic and operating conditions will return to pre-pandemic levels; these effects may differ from those assumed in our projected estimates. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business, mainly in our ability to place new capital equipment, primarily under long-term contracts, as a result of any economic impact that may occur in the future.
Use of Estimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates are required when establishing the allowance for credit losses and the net realizable value of inventory; determining future costs associated with warranties provided; determining the period over which our obligations are fulfilled under agreements to license product rights and/or technology rights; evaluating long-lived and intangible assets and investments for estimated useful lives and impairment; estimating the useful lives and standalone selling prices of instruments under leasing arrangements; determining the allocation of purchase price under purchase accounting; estimating the expense associated with the granting of stock; determining the need for, and the amount of a valuation allowance on deferred tax assets; determining the fair value of our embedded derivatives; and determining the value of the non-controlling interest in a business combination. Our actual results may differ from these estimates and there may be changes to those estimates in future periods.
Fair Value of Financial Instruments	The Company's financial assets based upon Level 3 inputs include embedded derivatives relating to its notes receivable. The Company determined the redemption features of its convertible note receivable represent an embedded derivative. The estimated fair value of the embedded derivative asset is evaluated through Level 3 inputs using a probability-weighted scenario analysis. The Company determined the warrant associated with its promissory note receivable represents a derivative. The estimated fair value of the derivative asset is evaluated through Level 3 inputs, using an enterprise valuation model. For additional information regarding the Company's notes receivable and derivatives, refer to Note 17, Notes Receivable. The estimated fair value of the Company's 3.75% Convertible Senior Notes due in 2026 (the "Notes"), is disclosed at each reporting period and is evaluated through Level 2 inputs with consideration of quoted market prices in less active markets. For additional information regarding the Company's accounting treatment for the issuance of the Notes, refer to Note 16, Convertible Notes. The Company's financial liabilities based upon Level 3 inputs include contingent consideration arrangements and notes payable relating to its acquisitions of Lacuna Diagnostics, Inc. ("Lacuna"), BiEsse A-Laboratorio die Analisi Veterinarie S.r.l. (“BSA”), and Biotech Laboratories U.S.A. LLC ("Biotech"). The Company is obligated to pay contingent consideration payments of $2.0 million in connection with the Lacuna acquisition based on the achievement of certain performance metrics within a twelve month period ("Initial Earn Out Period"), reducing to $1.0 million if such metrics were met in a twelve month period subsequent to the Initial Earn Out Period. The fair value of the Lacuna contingent consideration was $0 as of both December 31, 2021 and September 30, 2022. The Company is obligated to pay contingent consideration payments of $2.6 million in connection with the BSA acquisition based on the achievement of certain revenue metrics within three annual periods after 2021. The Company is obligated to pay contingent notes of up to $17.5 million in connection with the Biotech acquisition based on the achievement of certain product development milestones or at a predetermined date in the future, of which $14.9 million was outstanding as of September 30, 2022. Refer to Note 3, Acquisitions and Related Party Items for further discussion. The fair value of our contingent consideration and notes payable arrangements are determined based on a probability-weighted outcome analysis. The fair value of the contingent consideration and notes payable liabilities associated with future payments were based on several factors, the most significant of which are the financial and product development performance of the acquired businesses. For the contingent consideration liabilities, the Company will update its assumptions each reporting period based on new developments and record such amounts at fair value based on the revised assumptions until the agreements expire. Changes in fair value are recorded in the Condensed Consolidated Statements of Loss within General and administrative expenses. The note payable associated with the Biotech acquisition is not adjusted to fair value each period.
Revenue Recognition	Revenue Recognition With the acquisition of VetZ GmbH (“VetZ”) on January 3, 2022, the Company entered the market for veterinary practice information management software solutions (“PIMS”). Revenue for the sale of software licenses is recognized at a point in time upon delivery of the software. The software has significant stand-alone functionality, and provides the customer with the right to use the intellectual property as it exists at the point in time at which the license is granted. Revenue for support services, cloud-based services, and installation and training is recognized over time as the services are performed. Refer to Note 3 for further details regarding the VetZ acquisition. The Company may enter into contracts that represent a bill-and hold-arrangement, under which the Company bills a customer for product but retains physical possession of the product until some future point in time. For bill-and-hold arrangements, the Company recognizes revenue when control of the product transfers to the customer in accordance with the additional criteria in ASC 606-10-55-83.
Adoption of New Accounting Pronouncements	Adoption of New Accounting Pronouncements Effective January 1, 2022, we adopted ASU 2021-05, Leases (Topic 842), Lessors- Certain Leases with Variable Lease Payments. This guidance amends the lease classification accounting for lessors for certain leases with variable lease payments that do not depend on a reference index or a rate and would have resulted in the recognition of a loss at lease commencement if classified as a sale-type or direct financing lease. Under the new guidance, these leases will be classified as an operating lease. We evaluated the impact of the standard on our consolidated financial statements and the adoption of this ASU did not have a material impact on our consolidated financial statements and disclosures. Effective January 1, 2022, we early adopted ASU 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This guidance requires an acquiring entity to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At the acquisition date, the acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. We evaluated the impact of the standard on our consolidated financial statements and the adoption of this ASU did not have a material impact on our consolidated financial statements and disclosures.
