Sinister KennelInactive 8+ yrs

Bedford Hills, NY

Sinister Kennel appears in a third-party Boerboel breeder directory as a New York kennel, listed with a phone number and the website sinisterkennels.com; that entry carries a last-updated date of February 16, 2018 and no reviews ^[1]. Two dogs carrying the kennel's SINISTER prefix are recorded with OFA, one with a hip evaluation dated June 2011 and one with hip and elbow evaluations dated January 2016 ^[2]. The kennel's own website presented the operation as a South African Boerboel breeding program and carried a copyright notice running from 2004 ^[3]. That website no longer resolves ^[3]. No activity has been recorded for the kennel since; the most recent verifiable record is the February 2018 update to the directory listing ^[1], and the most recent health-testing result under the kennel's prefix is the January 2016 OFA evaluation ^[2].

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

Every dog screened for hips or elbows has its hip result on the public record. OFA lets owners keep abnormal results private, so a complete set is a deliberate choice to publish.
