The Bullmastiff was originally bred to aid gamekeepers in protecting the game on large English estates. The dog combines the reliability, intelligence, and willingness to please required in a dependable family companion and protector.
Are you interested in this breed? The OFA, working with the American Bullmastiff Association, recommends the following basic health screening tests for all breeding stock:
- Hip Dysplasia (OFA or PennHip)
- Elbow Dysplasia
- ACVO Eye Exam (Minimum of 12m)
- Cardiac (Including an echo)
- Autoimmune thyroiditis
Optional but recommended:
- Kidney Disease
Dogs meeting these basic health screening requirements are issued Canine Health Information Center (CHIC) numbers. For potential puppy buyers, CHIC certification is a good indicator the breeder responsibly factors good health into their selection criteria.
