Leventhal & Sons[1] On 26 April 2021, Patterson Veterinary Supply, Inc., has agreed to a deal to buy Miller Vet Holdings, LLC's assets.

[14] In 2016, a security researcher named Justin Shafer found 22,000 patients data on an FTP Server owned by Patterson Dental.

[15] 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."
