Sources before certainty
Dogiie references established veterinary resources, including the Merck Veterinary Manual and university veterinary centers. We explain differences between mating dates, hormone testing and confirmed ovulation, and clearly label estimates.
Authorship and medical review
We do not manufacture veterinary endorsements, credentials or patient testimonials. Unless an individual page names an actual qualified reviewer and date, our content should be regarded as not independently medically reviewed. Content involving medical decisions should be verified with a qualified veterinarian before being relied upon.
How corrections are handled
Visitors can report technical or factual concerns through the contact form. Updates should be evaluated against current clinical sources and dated in the page content where appropriate.
About our calculator
Date estimates are based on reference intervals, not a diagnosis or a guarantee of puppy arrival. See the calculator’s sources and its individual result explanation.
