PET DRx REPORTS 2008 FIRST QUARTER REVENUE UP 67% TO $17.8 MILLION

Conference Call on May 15^that 10:00 a.m. Eastern Time

NASHVILLE, Tenn. (May 14, 2008) — Pet DRx, Inc. (OTC BB: PDXC),a provider of veterinary primary care and specialized services to companion animals, today announced financial results for the three months ended March 31, 2008.

Revenue in the first quarter of 2008 was $17.8 million, up 67% compared with revenue of $10.7 million in the first quarter of 2007. The increase was primarily attributable to a full quarter contribution in 2008 of six hospitals acquired late in the first quarter of 2007. In addition, same store hospital revenue grew 3.1% compared with the first quarter of 2007. Same store hospitals are those that were owned and operated for all of the first quarter in 2007 and all of the first quarter in 2008, and include 20 facilities.

Hospital contribution margin improved to 9.6% from 3.4% in the prior-year first quarter. The improvement was primarily due to reduced costs of medical products and supplies as the Company began centralizing the purchasing of those products.

SG&A as a percent of revenue declined to 19.6% during the quarter from 24.0% in the same quarter a year ago. These figures exclude stock-based compensation and depreciation and amortization expense. Sequential declines in SG&A as a percent of revenue are expected to continue.

The net loss in the first quarter of 2008 was $3.0 million, or $0.13 per share, compared with a net loss in the first quarter of 2007 of $2.5 million, or $0.68 per share (adjusted for merger share conversion ratio). The net loss in the first quarter of 2008 includes interest expense of $1.2 million compared with $0.3 million in the prior-year quarter. Therefore, the loss from operations in the first quarter of 2008 was $2.1 million, down from $2.2 million in the same quarter a year ago.

As of March 31, 2008, the Company had cash and cash equivalents of $29.5 million, and $24.0 million in working capital.

“As you are aware, we have filed a listing application with NASDAQ and we are optimistic about becoming listed in the near term,” said Robert Wallace, Chief Executive Officer of PetDRx.

President and COO Steve Johnson said, “Our first quarter as a combined public company is also the first time the new management team has had an opportunity to focus on the business without being preoccupied with completing the merger with Echo. During the quarter, we began the implementation of several initiatives which allowed us to dramatically improve our hospital contribution margin.”

“Our initial efforts demonstrate the power of our hub and spoke strategy. The top 50% of our hospitals (ranked by contribution margin) achieved 10.1% year over year revenue growth and a weighted average margin of 19.6%,” said Johnson. “We continue to work on the facilities that have not performed in accord with our acquisition expectations.”

“We are actively engaged in discussions with a number of strategic acquisition candidates and expect to complete these transactions in the short term in our existing markets,” Wallace said. “These acquisitions will help us scale our business and achieve improved operating results.”

2008 Financial Guidance

Revising previously announced full year 2008 guidance, Pet DRx provided the following forecast:

• Same store revenue growth for the year between 5% and 10% for the 26 hospitals currently in its portfolio;

• Aggregate same store hospital operating margins increasing throughout the year, averaging 12% to 15% for the year, compared with 5% in 2007;

• Revenue, before acquisitions, in the range of $73 million to $77 million;

• Additional pro forma revenue in the range of $40 million to $60 million from acquisitions.
