This is a sources-sought synopsis, not a solicitation, intended to identify potential qualified sources and their size classifications relative to NAICS code 112990. The government will use responses to make acquisition decisions, and a separate solicitation will later be published on SAM.gov; interested offerors must respond to that solicitation as well. The requirement is for fully trained Patrol/Explosive and/or Patrol/Drug dogs under a DoD-wide program supporting the 341st Training Squadron (341 TRS). The effort is being sourced by the 772nd Enterprise Sourcing Squadron at Joint Base San Antonio (Lackland).
