What a Leedo reviewer does

The reviewer named on a resource evaluates the portions within that person's professional scope. Depending on the resource, that may include behavior explanations, assessment questions and result logic, training recommendations, safety management, equipment guidance, medical escalation language, or source selection.

Review of a public resource is not an evaluation or diagnosis of an individual reader's dog. Credentials and review scope should be read together; no single expert is presented as covering every discipline.

Additional reviewers

This directory will list each trainer, behavior professional, veterinarian, or other subject-matter expert once that person has accepted a defined public review role. Each profile will include:

  • current role and relevant credentials;
  • areas of expertise;
  • the scope of the person's work with Leedo;
  • links to the resources the person reviewed;
  • relevant professional affiliations; and
  • disclosures that could affect how readers interpret the work.

Veterinary review

Medical-adjacent claims are handled through a documented external veterinary-review process. Leedo does not name an individual veterinary reviewer publicly at launch. Internally, each completed review must record the qualified reviewer's identity and credentials, the material and version reviewed, the scope of the review, the review date, and any required changes.

Leedo does not label a page or claim as veterinary reviewed until that review and sign-off are complete.
