Going to the vet for a "fit to breed" exam does not exist.

We mean:

Has her dog had its hips AND knees AND elbows x-rayed and sent to a board of specialists? I.E. Orthopedic Foundation for Animals (OFA) and/or the University of Pennsylvania's Hip Improvement Program (PennHIP).

Has her dog had its eyes tested and cleared? I.E. Canine Eye Registration Foundation (CERF) and/or Optigen?

Has her dog had an EKG to see if he has heart problems?

What about thyroid testing?

Breeding is not easy. It is not profitable. Unless, of course, you breed like your cousin intends to. Then, it is profitable. But you're introducing a litter of new, unnecessary lives into a heavily overpopulated world.

Please, for the good of dogs, ask your cousin to SPAY and NEUTER her dogs.
