 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.

We would like to express our thanks to all our friends for their continued support and say a very big thank you to all the judges that have made all this possible.


Welcome to the Optimus Bullmastiffs Website.....

We hope you enjoy our dogs and that you find what you are looking for. If we can be of any help please feel free to contact us.
Our aim at Optimus is to breed quality Bullmastiffs that are both sound in movement and temperament and are a true representative of the breed. We have been involved with Bullmastiffs for over 30 years, and we are very proud to have bred and / or owned the Top Bullmastiff 1999, 2004, 2013, 2014, 2016, 2017 & 2018. Top Bitch 2002, 2003, 2006, 2007, 2013, 2015, 2016 & 2019. Top Puppy 2005, 2012, 2016 & 2019. Top Working Group Puppy 2019: Top Bullmastiff Brood Bitch 2006, 2015 & 2016. Top Breeder 2016, 2018 & 2019.
We are the only UK Kennel to have bred 2 World Champions - Ch Optimus Franklin (WW 2011, Int. Ch. & World Cup Winner 2011) & Ch. Optimus Rhondda JW (WW 2015 & IT Ch.) Ch. Optimus Holly - image copyright Cath Lewis

We are also the only UK kennel to have 2 UK Best in show winners at all breeds Championship shows - Ch. Old Manila`s Whisky Mac For Optimus JW and Ch. Optimus Daffyd JW, another first for our breed.
Ch. Optimus Daffyd JW also became the first Bullmastiff to win the KC Junior Warrant Competition overall, with the final being held at Crufts in 2018.

To top it all, two of our dogs hold the breed's Challenge Certificate record; our 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 who to date holds the record with 38 CCs. 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. Mac currently holds the breed record with 52 CCs.

We have based our 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.

We hope you enjoy looking at our dogs and can appreciate what we are trying to achieve with the breed. We only breed when we are looking for something which we feel will improve the Bullmastiff.


We are both approved Championship judges for the Bullmastiff and have undertaken appointments in the UK and Europe awarding CC’s and CAC’s respectively.

Occasionally we have puppies for sale to both show and pet homes with the importance being on the quality of the home for our puppy. If you are new to the world of show dogs, welcome and enjoy our wonderful hobby, take the highs and lows ...(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!
