Item 4. Purpose of Transaction.

The shares of Series C Preferred Stock, which were converted into shares of Common Stock that are the subject of this Schedule 13D, were acquired by Redwood West Coast, LLC pursuant to a Stock Swap Agreement dated October 31, 2002 between Redwood West Coast, LLC and Synbiotics Corporation. Pursuant to the terms of the Stock Swap Agreement, Redwood West Coast, LLC exchanged its 2,800 shares of Series B Preferred Stock of Synbiotics Corporation for 2,800 shares of Series C Preferred Stock of Synbiotics Corporation. These shares are convertible into 21,796,668 shares of Common Stock at any time. On April 7, 2005, Redwood West Coast, LLC converted 1,569 shares of Series C Preferred Stock into 12,215,907 shares of Common Stock. In addition, under certain circumstances as set forth in the Stock Swap Agreement, Redwood West Coast, LLC may be issued additional shares of Series C Preferred Stock by Synbiotics Corporation.

Each share of Series C Preferred Stock is convertible into such number of shares of Common Stock as is determined by dividing each share of Series C Preferred Stock, valued at $1,000, by the conversion price — initially set at $0.12846. The conversion price is subject to adjustment as set forth in the Certificate of Determination, as amended, establishing the Series C Preferred Stock including, without limitation, adjustments for stock splits, dividends and issuances by Synbiotics Corporation of additional shares of its Common Stock at prices below the applicable conversion price.

Holders of Series C Preferred Stock are entitled to vote with the holders of the Common Stock, as a single class, on each matter submitted to the shareholders of Synbiotics Corporation. Each share of Series C Preferred Stock represents that number of votes that equals the number of shares of Common Stock into which such shares of Series C Preferred Stock may be converted at the applicable conversion price. The voting rights granted to the holders of Series C Preferred Stock apply at all times. In addition, holders of Series C Preferred Stock, voting as a single class, have the ability to amend certain terms of such preferred stock. Accordingly, the Reporting Persons are deemed to have shared voting power over all of the shares reflected in this Schedule 13D related to the Series C Preferred Stock.

Redwood West Coast, LLC acquired the Common Stock and Series C Convertible Preferred Stock reflected in this Schedule 13D for purposes of controlling Synbiotics Corporation. Synbiotics Corporation has restructured its Board of Directors so that Redwood West Coast, LLC designees occupy 2 of the 3 seats on its Board. The Redwood West Coast, LLC Board seats are held by Messrs. Hendy and Donelan.

Redwood West Coast, LLC may purchase additional shares of Common Stock of Synbiotics Corporation, either in open market or privately negotiated transactions, for the purpose of increasing its ownership percentage of Synbiotics Corporation. Redwood West Coast, LLC notes that Synbiotics Corporation’s auditors have given it a “going concern” opinion because its cash position will not be sufficient to fund its operations and service its debt for the next twelve months if it also pays a $1,000,000 contractual obligation when it becomes due in July 2005. Redwood West Coast, LLC is considering the options that may be available to it and to Synbiotics Corporation with respect to such matters and other possible cash needs of Synbiotics Corporation. This involves, in part, consideration of whether Synbiotics Corporation should seek additional capital and whether the best interests of Synbiotics Corporation and its stockholders would be served by Synbiotics Corporation remaining a publicly held company or by becoming privately held.

Except as set forth above, the Reporting Persons do not have any plans or proposals which relate to or would result in:

4.1	The acquisition by any person of additional securities of the issuer, or the disposition of securities of the issuer;

4.2	An extraordinary corporation transaction, such as a merger, reorganization or liquidation, involving the issuer or any of its subsidiaries;

4.3	A sale or transfer of a material amount of assets of the issuer or of any of its subsidiaries;

4.4	Any change in the present board of directors or management of the issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board;

4.5	Any material change in the present capitalization or dividend policy of the issuer;

4.6	Any other material change in the issuer’s business or corporate structure;

4.7	Changes in the issuer’s charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the issuer by any person;

4.8	Causing a class of securities of the issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association;

4.9	Causing a class of equity securities of the issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or

4.10	Any action similar to any of those enumerated above.

Item 5. Interest in Securities of Issuer.

According to its Form 10-K filed with the Securities and Exchange Commission on March 22, 2005, as of March 21, 2005, Synbiotics Corporation had 21,606,126 shares of its Common Stock outstanding.
