 Optimus Barrington & Optimus Rhondda

The Record Breakers!

Father & Daughter Creating Breed History.

2016 was a fantastic year for us at Optimus and the fact that we are only a small kennel made it even more remarkable.
Our dogs had done very well in the show ring during the year and we were overjoyed when "Mac" went Best In Show at Border Union - a full group Championship dog show with an entry of 5776 dogs; something a Bullmastiff hadn't done for a very long time. Apart from that, it was towards the end of the year that Mac & his daughter Rhondda made breed history together.
"Mac" - Ch Old Manila’s Whisky Mac For Optimus JW at Midland Counties won his 41st Challenge Certificate with BOB & second place in the working group, breaking the Breed’s CC record of 40 CCs previously held by Ch Jaynos Big Bopper JW.
A month earlier at Belfast Mac's daughter World It Ch Optimus Rhondda JW won her 23rd Challenge Certificate with Best of Breed & 3rd place in the Working Group, making her the Bullmastiff Bitch CC record holder.
The previous record of 22 CCs had remained unbeaten for many years and was held by another home bred Optimus girl, Rhondda's great grandmother Ch Optimus Holly.

Mac & Rhondda had become the UK's 2 top winning Bullmastiffs of all time.

Welcome to the Optimus Bullmastiffs Website.....

I hope you enjoy my dogs and that you find what you are looking for. If I can be of any help please feel free to contact me.
My aim is to breed quality Bullmastiffs that are both sound in movement and temperament and are a true representative of the Bullmastiff breed. I have been involved with Bullmastiffs for over 25 years, and I am very proud to have bred and / or owned the Top Bullmastiff 1999, 2004, 2013, 2014 & 2016. Top Bitch 2002, 2003, 2006, 2007, 2013, 2015 & 2016. Top Puppy 2005, 2012 & 2016. Top Bullmastiff Brood Bitch 2006, 2015 & 2016.
I have also won Best of Breed at Crufts 2006 and Best Bitch at Crufts 2003 and 2009.
UK and Hungarian Champion Optimus Franklin is WW11 after taking Best of Breed at the World Dog Show 2011, he is the first UK bred Bullmastiff to become a World Champion. Franklin's litter sister "Scarlet" - UK Champion Optimus Scarlet is the 3rd generation of bitches to gain her title.

During August 2013 and within a week of each other Scarlet’s daughters; litter sisters - Optimus Labelle and Optimus Alicia JW (who was top Bullmastiff puppy 2012) have followed in their mother's footsteps becoming the 4th generation of Champion bitches here at Optimus.

We had a great start to 2014 with "Mac" - January saw him winning Reserve Best In Show at Boston and on February 1st he was crowned UK Bullmastiff of the year 2014 at the B.O.T.Y. later in the year he won BIS & 2 RBIS at 3 of the Championship dog shows he had attended.
At the end of 2014 Mac's success in the Show Ring put him top of the Working Group and overall #2 Top Dog - All Breeds.

At the World Dog Show 2015, Mac & Scarlet's daughter Ch Optimus Rhondda JW became an Italian Champion and followed in the footsteps of her uncle Franklin to become only the second UK bred Bullmastiff to gain a World Winner title. We are very proud to be the only UK Bullmastiff breeder to have bred 2 World Winners. 2015 & 2016 saw Mac winning Best in Show at a muliti group Championship dog show, something that hadn't been done by a Bullmastiff for over 20 years.

To top it all two of our dogs hold the breed's Challenge Certificate record; my home bred bitch Ch Optimus Holly (pictured) was the Bullmastiff Bitch CC record holder with 22 CC's until her record was beaten in September 2016 by another home bred Optimus Champion - her great granddaughter Rhondda. In October 2016 our Ch Old Manila's Whisky Mac for Optimus JW bred by Hilde Kjeldby & Glenn Hall of the Old Manila kennel in Norway exceeded all our expectations by breaking the Bullmastiff CC record winning his 41st CC at Midland Counties.

I have based my breeding on the famous Oldwell lines and hope to do this historic kennel proud in maintaining the true type of Bullmastiff.

Optimus dogs and their owners have also competed in Obedience and in Agility very rare for a Bullmastiff, but in the correct home it can be achieved.

I hope you enjoy looking at my dogs and can appreciate what I am trying to achieve with the breed. I only breed when I am looking for something which I feel will improve the Bullmastiff.


I'm an approved Championship judge for the Bullmastiff and have undertaken appointments in the UK and Europe awarding CC’s and CAC’s respectively. During 2012 I also had the pleasure of judging in the USA.

Occasionally I have puppies for sale to both show and pet homes with the importance being on the quality of the home for my puppy. If you are new to the world of show dogs, welcome and enjoy our wonderful hobby, take the highs and lo's ...(of which there will be more lows than highs)... with good grace, listen and learn from your elders and you will make many a true friend .... both canine and human.

Never forget your aim...to improve the breed!
