An exceptionally proven pedigree for the FEI levels, the talent, and rideability George Clooney offers is easily anticipated. At his Stallion Performance Test, George Clooney earned scores of 8 or higher in all categories. He placed in the Top 10 of the KWPN Stallion Competitions, the PAVO Cup Finals, and has shown through PSG/Intermediate I. A change in ownership has allowed George Clooney to introduce a new rider to the FEI levels, his super rideability made the transition easy.

George Clooney is sired by De Niro who was Reserve Champion of his performance test with a score of 141.93. De Niro had a wonderful sport career with over 24 wins at S-Level and has been consistently ranked at the top of the WBFSH Dressage Sire Rankings. George Clooney’s damsire Wolkentanz was Champion of his Licensing, Reserve Champion of his Stallion Performance Test, and winner of the Bundeschampionat. The combination of George Clooney’s dam bred to DeNiro has been extremely successful and includes full-siblings Despino and Delmar that are successful at Grand Prix. Maternal granddam Fricka is also the granddam of Isabel Werth’s Don Johnson.

George Clooney offspring are well received at both inspections and competitions. George Clooney has three licensed sons to his credit and his oldest offspring are now showing at the FEI levels. In 2022, the George Clooney son Killer the Dutch Young Rider Championship. In North America, his offspring are earning top ribbons in the hunters as well. He’s shown to improve elasticity in movement and we are also seeing a positive influence on rideability and temperament.

Mare Information
Mare Management Reminders

At Hilltop Farm we want to work closely with you and your veterinarian to ensure a successful breeding season and are available for questions at any time. The following information includes some basic suggestions as well as reminders on a few requirements for your breeding contract.

A Breeding Soundness Exam including a uterine culture is recommended, but not required, for all mares prior to breeding. If a mare fails to settle after two breeding cycles, Hilltop Farm will require a culture and cytology to be done at that time prior to any additional shipments of semen. We always recommend your vet checking your mare post-breeding to confirm ovulation. If a mare hangs on to a follicle longer than expected, it can be less expensive to ship additional semen than it would be to breed a second complete cycle. Getting your mare settled in foal is just the beginning. We recommend multiple pregnancy checks to help prevent cases of twins, misdiagnosed pregnancies, or lost time in the breeding season. The following schedule is what we recommend; only the first and fourth checks however are required by your breeding contract.

  • 1st check (Required): 14-16 days post ovulation – optimum time for vet to pinch off a twin if more than a single ovulation is noted.
  • 2nd check (Recommended): 28 days post ovulation – to confirm a viable pregnancy as the heartbeat normally appears by day 25.
  • 3rd check (Recommended): 35-40 days post ovulation – to confirm maintained pregnancy prior to endometrial cup formation. Mares that slip foals early may not come back into heat.
  • 4th check (Required): 55-60 days post ovulation – final confirmation of pregnancy in its critical first trimester.

Following your mare’s 14-16 day pregnancy check, please have your vet complete the Mare Breeding Passport received with your semen shipment and return it to Hilltop Farm. Any changes in pregnancy status after the 14-16 day check must be communicated to Hilltop Farm immediately. This Passport is used in all stallion reports to various breed registries and is used to generate a Breeding Certificate so that you can register your foal.

Registration Information

Your mare’s registration and approval play just as important of a role as the stallion’s approvals when determining registration options for your foal. Please keep in mind that in order to register your foal with a specific association, your mare may first need to be presented to that registry for approval. In addition to the registries a stallion is approved with, there may be additional registration options based on your mare’s eligibility and the stallion’s credentials. If you are confused at all on registration options for a potential foal, please speak with Hilltop Farm and your breed registry PRIOR to booking your breeding.
