Silverthorne Boerboels

Navasota, TX

Silverthorne Boerboels is operated by Morgan Jacoby in Navasota, Texas, and its AKC Marketplace profile lists the kennel as Silverthorne Boerboels & Staffordshire Bull Terriers, indicating Boerboels are bred alongside a second breed ^[1]. Morgan Jacoby of Navasota appears in Boerboel show records dating back to a 2015 IABCA roster ^[2] and a 2016 Brazos Valley Kennel Club event ^[3], and the AKC Marketplace profile displays an AKC Breeder of Merit badge ^[1]. Dogs registered under the Silverthorne prefix, an attribution that reflects a dog's breeder of record rather than its current owner, appear in the OFA database with hip, elbow, cardiac and eye evaluations recorded between 2022 and 2025, including four hip evaluations each graded Good and seven elbow evaluations recorded as normal ^[4] ^[5]. Dogs carrying that prefix also appear on the American Boerboel Club's Top Working Dogs lists for 2020 and 2025, with the 2025 entries recorded under third-party owners ^[6]. Texas Leontix states on its own site that its dog, AKC CH Leontix School of Rock, is co-owned with Morgan Jacoby ^[7]. The most recent verifiable activity is a Boerboel litter listed on that AKC Marketplace profile with a whelping date of April 28, 2026, followed by new photographs added to the profile in May 2026 ^[8] ^[1].

OFA Health Testing

View all records →

Public OFA records for dogs bred by this kennel, identified by the kennel prefix in each dog's registered name. A dog may have been owned by someone else when it was tested, so these records reflect what the kennel produced rather than what it currently owns. Counts include all-time history; scoring uses the past 5 years only.

Hip result disclosure

Hip results are public for 1 of 2 dogs screened for hips or elbows. Across all Boerboels in OFA's database the figure is 78%.

OFA screens hips and elbows on one application, and that form lets the owner keep a result off the public database if it comes back abnormal. One dog has an elbow evaluation on file with no matching hip evaluation. That usually means a hip result exists and was not released, though hips screened through PennHIP also stay off OFA unless the owner files them there as well. Either way the grade is not public, and the choice belonged to whoever owned the dog at the time, who is not always the kennel that bred it.
