Exhibit 99

Patterson Companies Reports Improved Second Quarter Operating Results

St. Paul, MN—November 21, 2007—Patterson Companies, Inc. (Nasdaq: PDCO) today reported consolidated sales of $741,992,000 for the second quarter of fiscal 2008 ended October 27, an increase of 7% from $694,273,000 in the year-earlier quarter. Net income came to $53,741,000 or $0.39 per diluted share, up 11% from $48,237,000 or $0.35 per diluted share in the second quarter of fiscal 2007.

Second quarter earnings benefited from an increase in the dental gross margin and further strengthening of the consolidated operating expense ratio, reflecting improvements in Patterson’s cost structure that have been achieved by consolidating distribution facilities and other functions at the corporate level. Revenues for this period were adversely affected by below-plan sales of dental equipment and software.

Sales of Patterson Dental, Patterson’s largest business, increased 4% to $534,505,000 in this year’s second quarter.

• Sales of consumable dental supplies and printed office products increased 7%.

• Sales of dental equipment declined 2% in the second quarter. Sales of CEREC 3D^® dental restorative systems, which were only modestly lower year-over-year, benefited from solid demand for the next-generation crown milling chamber that is sold both as an upgrade for existing installations and as an option on new system sales. Sales of basic dental equipment also were down slightly in the second quarter.

• Sales of other services and products, consisting primarily of technical service parts and labor, software support services and artificial teeth increased 13% in the second quarter.

Sales of the Webster Veterinary unit increased 14% in the second quarter of fiscal 2008 to $108,924,000. Sales of Patterson Medical, Patterson’s rehabilitation supply and equipment unit, rose 14% to $98,563,000, which included contributions from the eight branch offices that have been opened during the past year.

James W. Wiltz, president and chief executive officer, commented: “Patterson Dental recorded a mixed performance in this year’s second quarter, but on balance, we are disappointed with the overall results of this unit. Sales of consumable dental supplies were solid during this period, but sales of dental equipment and software fell short of forecasted levels. Sales growth of Patterson’s veterinary business remained strong in the quarter, and the positive outlook for this unit is reinforced by the anticipated impact of two important flea and tick medications that were introduced late in the second quarter. We also are encouraged by the initial results of Patterson Medical’s branch office strategy, which is making a solid contribution to the growth of our rehabilitation business. The recent acquisition of a developer of industry-leading practice management software for physical therapists, while not expected to have an immediate impact on Patterson Medical’s sales growth, should further strengthen the full-service, value-added business platform of our rehabilitation unit.”

Wiltz continued: “We are cautious about the near-term outlook of our equipment business, since it appears that certain economic and industry conditions may be causing some customers to temporarily delay new capital investments in their practices. Given this uncertainty, we are forecasting earnings of $0.44 to $0.46 per diluted share for the third quarter of fiscal 2008 ending January 26, 2008. We also are reducing our full-year fiscal 2008 guidance to $1.68 to $1.72 per diluted share from the previously-issued guidance of $1.73 to $1.77.”
