## Criticism and controversy
### FTP server data breach

In 2016, a security researcher named Justin Shafer found 22,000 patients data on an FTP Server owned by Patterson Dental. He was reportedly raided by the FBI.

### Animal welfare issues

In 2017, photographs captured by a former employee of a Texas blood bank that Patterson Veterinary distributed products from showed greyhounds under duress. PETA revealed pictures and video taken at The Pet Blood Bank showing kenneled dogs with open wounds, rotting teeth and severely overgrown toenails. According to The Washington Post, "Pet Blood Bank owner Shane Altizer did not deny that the images were taken there, but said they predated his 2015 purchase of the company or were “moment snapshots” unrepresentative of overall conditions now." A veterinarian who visited the facility earlier in the year said she found the dogs to be in satisfactory condition but after seeing the pictures, believed that “(T)he facility was ‘cleaned up’ before our touring...This certainly suggests that regional, state and/or federal regulation is warranted.”
On its website, Patterson said it had "ceased doing business" with the blood bank, which subsequently closed.

### FTC antitrust

In 2019, the FTC ruled that Patterson Dental, Henry Schein, Inc., and Benco Dental violated antitrust law by refusing to compete for the business of buying groups by colluding with each other.
On November 8, 2019 the FTC's website states: "Judge Chappell held that Benco Dental Supply Company and Patterson Companies, Inc. conspired to refuse to provide discounts to, or otherwise serve, buying groups representing dental practitioners. The judge dismissed the charges against the third respondent, Henry Schein, Inc. "
