MiDOG Expands Whole-Genome Sequencing Service for Faster Veterinary Diagnostics

MiDOG Animal Diagnostics announced an expanded whole-genome sequencing diagnostic service on March 10, 2026, positioning the updated pipeline as an "all-in-one microbial WGS test" for veterinary clinics and labs. The headline on the company's product page put it plainly: "Say Goodbye to PCR Panels. MiDOG Expanded Testing Now Includes Parasites."

The expansion adds parasite detection to a service that already covered bacteria and fungi. Every sample is screened against a database containing 64,800 bacterial species and a separate database of 4,100 fungal species. Parasite screening taps a database of 4,300 organisms, though MiDOG's own materials note that samples "can be screened" against that database, a phrasing distinction that leaves open whether parasite testing is automatic or ordered separately.

Beyond organism identification, the expanded service screens for toxin- and biofilm-related markers that may contribute to chronic or treatment-resistant infections. Resistance screening is included, covering 47 antibacterial and 9 antifungal drug options, with the stated goal of identifying which treatments will work and which won't.

MiDOG positioned the service as particularly useful in cases where conventional diagnostics fall short. The company described the test as "especially valuable in culture-negative, polymicrobial, chronic, recurrent, or treatment-resistant cases where conventional diagnostics may be inconclusive," and noted it can detect fastidious, slow-growing, or difficult-to-culture organisms that traditional panel approaches might miss. The underlying argument against PCR panels is straightforward: targeted assays require knowing what you're looking for, while whole-genome sequencing assesses the full microbial picture in a single pass.

Each test includes a free veterinary consultation, which MiDOG lists as a standard service inclusion.

Several operational details were not included in the March 10 announcement: turnaround time, accepted sample types, pricing, laboratory location, and accreditation status were not disclosed. The workflow and ordering process sections on the company's product page exist but their full content was not available at time of reporting. For dogs dealing with persistent, unresolved infections that have stumped standard culture and sensitivity testing, the expanded MiDOG panel represents a tool worth asking your vet about, though confirmation of those practical logistics will matter before it becomes a routine part of the diagnostic toolkit.
