In short, the Embark for Breeders kit is intended for breeders, while both the Breed + Health and the Dog DNA Test for Purebred Pet kits are intended for pet owners.
The Embark for Breeders kit includes tests for genetic diversity COI, health conditions, and traits. You can find the conditions we test for here: https://embarkvet.com/breeders/health/ and the traits we test for here: https://embarkvet.com/breeders/traits-list-for-breeders/).
Embark for Breeders offers only breed confirmation, unlike the pet owner-oriented ones that gives detailed breed and ancestry, but Embark for Breeders does include an OFA submission report, access to breeder-specific tools and features, and breeder-focused emails and promotions.
