Kilroy Bullmastiffs began in 1990 as a family affair. Our daughter, Terri, and her husband decided that they wanted a Bullmastiff as a family   companion. We ended up getting the littermate to our daughter’s dog. Shortly afterwards, our daughter decided she wanted to show her dog and we followed in her footsteps.

We bred our daughter’s dog, Ch. Praetorian Murphy’s Law, to a dog on the East Coast and that produced the foundation of our Bullmastiffs today. There were only two offspring from this breeding of which Ch. Kilroy’s Postcard From Boston, ROM was Winner’s Dog at our 1994 National Specialty here in California. That was quite an exciting moment for us.

Through the years we have produced 24 American & Canadian Champions including a multi-Best in Show dog.

We OFA hips & elbows, thyroid, and heart. Our goal is to have healthy and sound Bullmastiffs with great temperaments.
